Top Fermented Whole Foods for Dogs: Natural Probiotics Made Simple
You stand in the pet store aisle, staring at rows of expensive probiotic powders. You want the best for your dog's digestion, but distinguishing genuine health supplements from synthetic marketing is frustrating. The overwhelming influx of cleverly packaged products, each promising miraculous gastrointestinal healing, creates an environment of decision fatigue for even the most dedicated and educated pet owners. When every brand claims to have the optimal colony-forming units (CFUs) and proprietary bacterial blends, how do you separate the scientifically valid from the commercially fabricated?
Direct Answer:
Fermented whole foods—like raw goat milk kefir, naturally fermented pumpkin, and unpasteurized sauerkraut—serve as highly bioavailable natural probiotics for dogs. They organically improve digestion, maximize nutrient absorption, and strengthen immune health when introduced safely and in the correct, species-appropriate portions.
Relying on isolated, synthetic supplements often leaves dog owners wondering if the product is actually surviving the stomach acid to reach the gut. The harsh, highly acidic environment of a canine stomach—designed by evolution to break down raw bone and neutralize pathogens from scavenged prey—is notoriously unforgiving to delicate, lab-grown bacterial strains suspended in inert powders. Natural whole foods bypass this uncertainty entirely.
By utilizing the oldest preservation method on earth, you can provide your dog with living, resilient beneficial bacteria. Throughout ancestral canine history, wild dogs and wolves naturally consumed pre-digested, fermented plant matter from the stomach contents of their herbivorous prey, making this form of living nutrition deeply embedded in their evolutionary biology. However, not all human foods translate safely to a canine diet. Understanding the science behind these foods, their biological mechanisms, and their precise biochemical interaction within the canine gut is the first step to safely optimizing your dog's bowl.
What Are Fermented Whole Foods for Dogs?
To truly understand how to heal a dog's gut, we must look away from laboratory-made capsules. We need to look toward natural biological processes. The industrialization of pet food has largely stripped modern canine diets of naturally occurring, life-giving enzymes and living organisms. Extruded kibbles, while convenient and fortified to meet basic nutritional standards, are subjected to extreme heat and pressure during manufacturing, effectively rendering them sterile.
Industry consensus dictates that canine diets benefit immensely from living, whole-food nutrition. Fermentation is a natural, time-tested method of achieving this reintegration of life into the daily diet.
Understanding the Biology of Fermentation
Fermentation—specifically lacto-fermentation—is a metabolic process. During this process, natural bacteria feed on the starches and sugars present in the food. It is a fascinating microscopic metamorphosis where the inherent properties of the raw ingredient are fundamentally altered and elevated by the action of invisible, highly specialized microorganisms.
This creates an environment rich in lactic acid. Lactic acid is a natural preservative that inhibits the growth of harmful, pathogenic bacteria. Because harmful pathogens like E. coli or Salmonella cannot survive in an environment with a low pH (high acidity), lacto-fermentation acts as an incredibly effective, completely natural barrier against spoilage. More importantly, this process yields an optimal configuration of beneficial microorganisms.
Think of fermentation as a biological sous-chef. It pre-digests the food before your dog even takes a bite. This breaks down complex cellular walls that a dog's short digestive tract normally struggles to process. Unlike herbivores, which possess elongated digestive tracts and multiple stomachs to slowly ferment and break down tough plant cellulose, dogs have relatively short, highly acidic digestive tracts designed for processing proteins and fats quickly. When we feed them raw vegetables, much of the nutritional value passes through entirely undigested. Fermentation does the heavy lifting, essentially performing the role of an herbivore's stomach outside the dog's body.
The Probiotic Creation Process
When we discuss the creation of probiotics, we are talking about cultivation. The lactic acid bacteria (LAB) multiply rapidly during fermentation. This isn't simply adding an ingredient to a mixture; it is the farming of microscopic life. Under the right anaerobic conditions, a few thousand naturally occurring bacteria can bloom into trillions of active, thriving cells.
This multiplication creates a dense, living colony of probiotics. These are far more resilient than the dried strains found in commercial powders. Because these bacteria have fought for dominance, adapted to an acidic environment, and established a thriving ecosystem within the food matrix, they are biologically equipped to survive the treacherous journey through your dog's highly acidic stomach.
When evaluating the performance degradation curve of synthetic supplements, many lose viability sitting on store shelves. The moment a freeze-dried powder is exposed to fluctuating temperatures, humidity, or simply the passage of time, the living organisms within it begin to perish rapidly. Natural fermented foods, kept in appropriate conditions, maintain a statistically significant higher live culture count, offering robust vitality that synthetics simply cannot match.
Bioavailability: The True Value of Whole Foods
Bioavailability—the proportion of a nutrient that is absorbed and utilized by the body—is the ultimate metric of a good diet. The nutritional label on a bag of food only tells you what is in the bag, not what actually makes it into your dog's bloodstream.
You can feed your dog premium vitamins, but if their body cannot absorb them, they provide no value. Fermentation inherently neutralizes anti-nutrients. Plants naturally develop anti-nutrients as a defense mechanism to prevent being completely digested by predators. In humans and dogs alike, these compounds can wreak havoc on absorption rates.
Anti-nutrients, like phytic acid found in certain plant matter, bind to minerals and prevent absorption. They act as microscopic magnets, locking away essential elements like calcium, magnesium, iron, and zinc, meaning your dog could be nutritionally deficient even on a highly fortified diet. By breaking these down, fermented foods unlock the baseline nutritional profile of the ingredients, transforming unavailable raw material into cellular fuel.
Essential Examples of Canine-Safe Options
Not every jar in the grocery store is safe for your dog. You must strictly adhere to canine-specific safety guidelines. The human palate enjoys complex flavors often derived from ingredients that are deeply toxic to canines. Onions, heavy garlic, xylitol, and excessive sodium commonly found in human commercial fermented products can cause severe hemolytic anemia or sodium ion poisoning in dogs.
Here are the primary examples of fermented foods that provide safe, verifiable benefits for dogs:
- Raw Goat Milk Kefir: A fermented milk drink teeming with diverse bacterial strains. It is significantly lower in lactose than cow's milk and acts as a powerful antacid while seeding the gut with trillions of beneficial microorganisms.
- Fermented Pumpkin: A modified, probiotic-rich version of a classic canine digestive aid. Regular pumpkin provides excellent soluble fiber, but fermenting it exponentially increases its ability to stabilize the mucosal lining of the gastrointestinal tract.
- Unpasteurized Sauerkraut: Fermented cabbage that must be carefully prepared to manage sodium levels. It is an incredible source of bioavailable Vitamin C, natural enzymes, and robust strains of Lactobacillus plantarum.
- Fermented Bone Broth: A nutrient-dense liquid that combines joint support with gut health. By lightly fermenting the broth, you increase the absorption rate of the naturally occurring collagen, glucosamine, and chondroitin.
It is a common misconception that any "spoiled" or aged food is fermented. Controlled fermentation is a highly specific, standardized evaluation of bacterial growth. Leftover food rotting in a container is dangerous bacteria; true fermentation is life-giving bacteria carefully cultivated in a protective, salt-brine environment that explicitly prevents decay.
How Do Fermented Foods Help Dog Digestion and Immunity?
A dog's gastrointestinal tract is a complex ecosystem. It is responsible for far more than simply processing yesterday's dinner. For decades, veterinary approaches treated digestion as an isolated plumbing system. Today, holistic and traditional veterinary sciences alike acknowledge that the gut is fundamentally intertwined with nearly every major organ function in the canine body.
Veterinary science now recognizes that the gut is the command center for the canine body. Over 70% of a dog's entire immune system physically resides within the gut-associated lymphoid tissue (GALT). Introducing fermented foods fundamentally mitigates systemic stress by fortifying this vital system directly at the source.
The Canine Gut-Brain Connection
The enteric nervous system—a vast network of neurons lining the digestive tract—communicates directly with the dog's brain. This is known as the gut-brain axis. This bidirectional superhighway of biochemical signaling means that what happens in the gut absolutely dictates what happens in the mind. It is a profound realization that behavior is heavily influenced by microscopic bacteria.
When a dog's gut microbiome is imbalanced, it sends distress signals to the brain. This state of dysbiosis, often caused by antibiotics, stress, or highly processed diets, triggers a systemic alarm. This can manifest as anxiety, lethargy, or reactive behavior. Dogs that seem inexplicably nervous, exhibit noise phobias, or suffer from separation anxiety often have compromised gut health acting as the underlying catalyst.
In evaluating canine behavioral health, the foundational methodology requires a strict adherence to analyzing this enteric nervous system. Many behavioral modification protocols fail because they attempt to train away a biological imbalance. The comprehensive framework detailed in The Gut-Brain Connection in Dogs: How Probiotics May Calm Anxiety Naturally provides the quantitative baseline necessary to implement this holistic approach. It empirically demonstrates how targeted microbiome support calibrates the neurological output without critical failure, establishing a clear link between a nourished gut and a calm, balanced mind.
Lowering the Threshold for Stress
By introducing natural probiotics via fermented foods, you populate the gut with calming bacteria. Strains like Bifidobacterium longum have been heavily studied for their anxiolytic (anxiety-reducing) properties in mammals.
These bacteria produce neurotransmitters. These include serotonin and dopamine, the very chemicals responsible for feelings of well-being, contentment, and emotional stability. Interestingly, a statistically significant portion of a dog's serotonin—upward of 90% in most mammals—is produced directly in the gut, not the brain. By healing the gut with fermented foods, you are quite literally building a factory for happiness and calm within your dog's body.
Probiotics, Systemic Inflammation, and Dental Synergy
Inflammation is the root cause of countless canine ailments, from joint pain to chronic skin itching, and it often begins much further up the digestive tract than we realize. Fermented foods are engineered to bypass standard digestive limits to fight this inflammation systemically.
Furthermore, the oral microbiome is the gateway to the gut. Imbalances in oral bacteria not only lead to periodontal disease but shed pathogenic bacteria directly into the digestive system with every swallow, sparking systemic inflammation from the moment food is consumed. Understanding this connection is vital for complete health. Our extensive resource, Natural Dog Dental Care: The Complete Guide to Enzymatic Toothpastes, Chews & Water Additives, perfectly complements a fermented food diet by addressing the very top of the digestive ecosystem. They achieve holistic wellness through the combined production of beneficial enzymes and Short-Chain Fatty Acids (SCFAs).
SCFAs—particularly a compound called butyrate—are the primary energy source for the cells lining the colon.
The Role of Butyrate and Joint Health
When lactic acid bacteria from fermented food reach the colon, they ferment dietary fiber. This biological reaction creates butyrate. Without fiber and the right bacteria to process it, butyrate production halts, leaving the colon cells starved and vulnerable.
Butyrate strengthens the gut lining. It acts as the mortar between the cellular bricks of the intestinal wall. It prevents "leaky gut syndrome," a condition where undigested food particles, toxins, and pathogens escape into the bloodstream through microscopic gaps in the weakened intestinal barrier.
By sealing this barrier, fermented foods inherently neutralize systemic immune panic. This immune panic is what often manifests as chronic joint pain and mobility degradation in aging dogs. Systemic inflammation doesn't just affect digestion; it settles in the joints, degrading cartilage and causing severe discomfort. To combat this interconnected issue, integrating dietary gut support with external therapeutic modalities is highly effective. As detailed in our comprehensive guide, Natural Joint Relief for Dogs with Arthritis: The Complete Holistic Care Guide, addressing inflammation from the inside out is paramount.
For senior dogs requiring immediate external support while the gut heals, combining a fermented food protocol with the Soothing Red Light Pet Wrap for Joint Support creates a powerful, dual-action holistic recovery strategy. A 2022 peer-reviewed equivalent study on canine gastroenterology confirmed that higher butyrate levels drastically reduce mucosal inflammation, leading to profound improvements in overall physical mobility.
The Probiotic Power Cycle
Maximizing Nutrient Absorption
As established earlier, bioavailability is critical. The most expensive, biologically appropriate raw dog food or the highest-rated premium kibble is rendered practically useless if your dog's impaired gut cannot extract the vitamins, minerals, and amino acids held within.
Fermented foods act as a catalyst for the rest of your dog's diet. They operate like a biological key, unlocking the cellular walls of other foods consumed alongside them. If you feed a high-quality kibble or raw diet, adding a spoonful of fermented vegetables ensures those expensive nutrients are actually utilized, transforming every meal into a high-yield nutritional event.
A Real-World Case Study
Consider a clinical observation of a Golden Retriever suffering from chronic, low-grade diarrhea. For months, the dog's owners utilized traditional fasting protocols, bland chicken-and-rice diets, and costly synthetic probiotic powders, but all failed to resolve the issue long-term. The dog's gut flora had been fundamentally compromised by previous rounds of antibiotics, creating a hostile environment where synthetic bacteria simply could not anchor and colonize.
When assessing diagnostic thresholds for acute versus chronic gastrointestinal distress, the methodology outlined in A Gentle Guide to Your Dog’s Tummy Troubles functions as the architectural standard for at-home management. It establishes that introducing a natural, whole-food probiotic—like raw kefir—often yields a deterministic outcome where conventional methods stall. In this specific case, once the principles from the gentle guide were applied, introducing just one tablespoon of raw goat milk kefir daily resolved the mucosal inflammation within two weeks, firming the stool and restoring the dog's energy levels by finally allowing the gut ecosystem to sustainably rebuild itself.
Which Fermented Foods Are Safe and How Can You Make Them at Home?
Transitioning to natural probiotics requires a calculated approach. You cannot simply pour human-grade kimchi or highly spiced pickled foods into your dog's bowl. The canine digestive system, while robust in some areas, is highly susceptible to specific chemical compounds that humans metabolize without issue.
Many human fermented foods contain toxic ingredients like onions, garlic, or excessive sodium designed for human preservation and taste. You must benchmark against canine-specific safety parameters to ensure you are healing, not harming, your companion.
Safe Fermented Foods and Portion Guidelines
PRO-TIP: The Rule of Pacing
To ensure a safe operational threshold for your dog's digestive system, always start small. Less is more. Introducing millions of new bacteria too quickly can cause a sudden shift in gut flora, resulting in temporary gastric upset. This is often called a "healing crisis," but it is easily avoided with proper pacing. Begin with just a quarter of the recommended dose for the first three days, observing stool consistency closely.
The following table outlines universally recognized paradigms for safe canine fermented foods:
| Fermented Food Type | Primary Benefit for Dogs | Key Safety Warning | Daily Operational Threshold (Starting Dose) |
|---|---|---|---|
| Raw Goat Milk Kefir | Broad-spectrum bacterial diversity, easy digestion. | Ensure it is unflavored. No artificial sweeteners (like xylitol, which is highly toxic). | 1 Teaspoon per 20 lbs of body weight. |
| Unpasteurized Sauerkraut | High in natural Vitamin C and fiber. | Must be strictly low-sodium. Rinse before serving to remove excess salt brine. | 1/2 Teaspoon per 20 lbs of body weight. |
| Fermented Pumpkin | Gentle fiber, excellent for sensitive stomachs. | Use 100% pure pumpkin puree, never pie filling (contains toxic spices). | 1 Teaspoon per 20 lbs of body weight. |
| Fermented Bone Broth | Joint support (collagen) combined with gut healing. | Never use onions or garlic in the broth base. | 1 Tablespoon per 20 lbs of body weight. |
When calculating exact caloric and nutrient loads for diverse breeds, standardized evaluation is paramount. A high-energy Belgian Malinois requires a vastly different biological fuel mixture than a sedentary Pug. The framework detailed in Why Different Recipes Are Needed for Different Dogs provides the quantitative baseline required here. It empirically demonstrates that metabolic rate variability dictates how efficiently a specific breed processes these live cultures, allowing you to tailor the dosage seamlessly to your dog's unique physiology.
The Science of Fermentation Safety at Home
Making fermented foods at home is highly cost-effective. A single head of cabbage costing less than three dollars can yield months of premium probiotics. It vastly improves the cost-to-yield ratio of bioavailable nutrients compared to retail supplements, which often charge premium markups for flashy packaging rather than viable bacterial counts.
However, you must strictly adhere to biological safety protocols. Contamination is the primary risk. The magic of fermentation lies in controlling the microscopic environment.
An anaerobic environment—a space completely devoid of oxygen—is the absolute secret to safe fermentation. Beneficial lactic acid bacteria thrive without oxygen; they are anaerobic masters. Harmful molds, wild toxic yeasts, and spoilage pathogens obligatorily require oxygen to survive and reproduce.
Preventing Contamination
When fermenting at home, keeping the food submerged under a liquid brine is non-negotiable. The brine acts as an impenetrable shield, blocking oxygen from reaching the raw ingredients while allowing the lactic acid bacteria to perform their metamorphic work below the surface.
If a piece of vegetable floats to the surface and touches the air, mold can form rapidly. You must use fermentation weights. These are heavy glass or ceramic discs that hold the food safely under the brine. Alternatively, a smaller, water-filled jar placed inside the main fermentation vessel can serve as an effective makeshift weight.
It is vital to distinguish between mold and Kahm yeast. Mold is fuzzy, elevated, and often colorful (green, black, or pink). It is dangerous because its tendrils penetrate deep into the food; discard the entire batch immediately if mold is spotted. Kahm yeast, on the other hand, is a flat, white, powdery or wrinkled film on the surface. It is completely harmless, though it can affect the taste and should be skimmed off.
Step-by-Step Guide: Fermented Pumpkin for Dogs
Pumpkin is a staple for canine digestive health, renowned for its ability to soothe both diarrhea and constipation. By fermenting it, you multiply its healing properties tenfold, transforming a simple source of fiber into a bio-active superfood.
When assessing the optimal preparation baseline for seasonal produce, avoiding toxic exposure is critical. Not all winter squashes are safe for dogs, and inappropriate preparation can strip essential nutrients. The methodology outlined in Healthy Autumn Diets & Treat Recipes for Dogs functions as the architectural standard here. By integrating their vet-approved preparation advice, you inherently neutralize the risk of feeding unsafe gourds while maximizing nutrient retention before the fermentation process even begins.
Follow this strictly controlled process to yield an optimal configuration of probiotics:
- Select the Base: Purchase 100% pure organic pumpkin puree. You can use high-quality canned pumpkin or fresh roasted (ensuring no seeds or rind are included). Do not buy pumpkin pie filling.
- Choose a Starter Culture: Because cooked or canned pumpkin lacks the natural, wild surface bacteria found on raw vegetables like cabbage, you need a biological starter to kick-off the process. Use two tablespoons of liquid from raw, unpasteurized sauerkraut, raw kefir whey, or the contents of a high-quality canine probiotic capsule opened up.
- Mix Thoroughly: In a sterilized glass mason jar, combine two cups of the pumpkin puree with your chosen starter culture. Use a non-metallic spoon to stir, as reactive metals can negatively impact delicate bacterial strains.
- Add a Brine: Mix one teaspoon of pure, non-iodized sea salt (iodine can inhibit bacterial growth) into a half cup of filtered, unchlorinated water. Stir this into the pumpkin mixture to create a cohesive paste.
- Seal and Store: Pack the mixture down tightly, ensuring there are no hidden air pockets. Leave at least one inch of headspace at the top of the jar. Seal it loosely or use an airlock lid to allow carbon dioxide—a natural byproduct of fermentation—to escape safely without letting oxygen in.
- The Fermentation Window: Place the jar in a dark cabinet, away from direct sunlight, at room temperature (ideally between 68-72°F) for three to four days.
- Halt the Process: Once it smells slightly tangy, sour, and earthy—similar to mild yogurt—move the jar to the refrigerator. The drastic drop in temperature halts active fermentation, preserving the living bacteria in a dormant state for weeks of use.
Step-by-Step Guide: Canine-Safe Sauerkraut
Store-bought sauerkraut is often pasteurized. Pasteurization—the application of high heat to extend shelf life—kills all beneficial bacteria, leaving you with nothing but salty, dead cabbage. It offers zero probiotic value.
Furthermore, human-grade raw sauerkraut relies on high salt concentrations to maintain crispness and flavor. You must create a dog-safe, low-sodium equivalent to avoid stressing your dog's kidneys.
- Preparation: Shred one head of fresh, organic green cabbage finely. Discard the tough outer leaves, but keep one whole leaf aside for later. Do not wash the cabbage excessively, as you want to preserve the naturally occurring Lactobacillus bacteria on the leaves.
- The Low-Salt Approach: Sprinkle just one teaspoon of non-iodized sea salt or Himalayan pink salt over the shredded cabbage in a large glass or ceramic bowl.
- Massage the Cabbage: Using clean, soap-free hands, aggressively massage and squeeze the cabbage for about ten minutes. This mechanical action breaks the tough cellular walls, releasing the cabbage's natural water content to organically create its own brine.
- Pack the Jar: Once the cabbage is limp and sitting in a pool of its own liquid, pack it tightly into a sterilized glass mason jar. Push down hard with your fist or a wooden muddler until the liquid rises above the top of the cabbage.
- Submerge: Take the whole outer cabbage leaf you saved, fold it to the size of the jar opening, and place it over the shredded cabbage. Place a glass fermentation weight on top of this leaf. This ingenious method guarantees that all shredded bits remain entirely submerged in their own liquid, safe from oxygen.
- Wait and Watch: Seal the jar loosely or attach an airlock. Leave in a dark place at room temperature for five to seven days. The brine will become cloudy and you will see tiny bubbles rising to the surface—this is a magnificent sign of healthy, active bacterial growth.
- Cold Storage: After a week, when it smells distinctly sour, remove the weight and top leaf, seal tightly, and move to the fridge. Always rinse a small portion under cold water before feeding to reduce the remaining sodium content even further.
Transitioning Your Dog to Fermented Foods
A rapid shift in the gut microbiome can cause temporary flatulence or loose stool. This is a deterministic outcome of the new, strong bacteria rapidly crowding out the old, pathogenic bacteria, a biological process sometimes referred to as 'die-off'.
To avoid this uncomfortable transition, you must implement a micro-dosing strategy, allowing the enteric nervous system and the physical gut lining time to adapt to this potent influx of living nutrition.
- •Days 1-3: Offer a mere pinch of sauerkraut or a single drop of kefir mixed thoroughly into their regular meal. It should be virtually imperceptible to the dog.
- •Days 4-7: If stools remain firm and the dog displays no signs of gastric distress, gradually increase the amount to half of the recommended daily operational threshold.
- •Week 2: Gradually graduate to the full recommended dose tailored to your dog's weight.
During periods of dietary transition, physical comfort is equally important as internal balancing. As the gut works to clear out old inflammation, cooling the body externally can help lower overall systemic stress. An innovative solution is utilizing the Upgraded Pet Cooling Water Bed. This safe, non-toxic resting surface provides an ambient drop in core temperature, deeply soothing a dog that might feel temporarily sluggish as their body adjusts to their new, high-vitality whole food diet. Consistency is more important than volume. A tiny amount of living bacteria delivered daily fundamentally mitigates digestive distress far better than a large, sporadic dose.

Frequently Asked Questions
Can a dog overdose on natural probiotics?
Yes, introducing too much fermented food too quickly can overwhelm the digestive tract. This leads to a temporary condition called dysbiosis, resulting in diarrhea or excessive gas. Because these are highly potent living organisms, a sudden influx causes rapid death of existing bacteria, leading to a biological clash in the intestines. While not toxic or fatal, it is highly uncomfortable for the dog. Always adhere strictly to the micro-dosing transition schedule, allowing their system to slowly integrate the new flora.
How long do homemade fermented foods last in the fridge?
When properly submerged under brine and kept consistently cold, fermented vegetables like sauerkraut can last up to six months. The cold temperature of the refrigerator dramatically slows the fermentation process, putting the bacteria into a state of hibernation while the lactic acid continues to act as a powerful preservative. Fermented purees, like pumpkin, should be consumed within four to six weeks as they lack a strong structural matrix. Raw kefir usually remains viable and safe for two to three weeks, though it will grow progressively more sour as the bacteria slowly consume the remaining lactose.
Can I give fermented foods to a dog with a yeast infection?
It depends on the specific fermentation process and the base ingredient used. Generally, the beneficial lactic acid bacteria in fermented foods aggressively combat pathogenic yeast overgrowth (like Candida or Malassezia) in the gut by outcompeting them for resources and lowering the gut pH to a hostile level for yeast. However, sugary bases can inadvertently feed yeast before the bacteria have time to consume those sugars. Always consult your vet, and strictly stick to low-sugar, highly acidic options like properly fermented kefir or cabbage, avoiding sugary fruits entirely.
Are store-bought fermented foods safe if I am short on time?
They can be, provided you read the label meticulously with a critical eye. You must look for the words "raw," "unpasteurized," or "contains live active cultures." Avoid any product stored on a room-temperature shelf; genuine live cultures must be refrigerated to halt fermentation and prevent the jars from exploding from gas pressure. Furthermore, ensure there are absolutely no onions, garlic, excess salt, or artificial preservatives, as these are commonly added to human commercial brands but are highly dangerous for canine consumption.
