Size and fit guide
Measure Nose Distance and Chest Girth
Choose a size that matches both measurements. The halo should sit ahead of the face while the harness stays secure without rubbing the neck, chest, or shoulders.
How to measure
- Measure from the chest area to just beyond the nose for the nose-distance limit.
- Measure around the widest part of the chest.
- Match both numbers to one row before ordering.
| Size | Nose distance | Chest girth |
|---|---|---|
| XXS | Up to 9.8 in / 25 cm | 11.8-21.6 in / 30-55 cm |
| XS | Up to 13.8 in / 35 cm | 14.9-24.4 in / 38-62 cm |
| S | Up to 15.7 in / 40 cm | 16.5-31.5 in / 42-80 cm |
| M | Up to 19.7 in / 50 cm | 16.5-31.5 in / 42-80 cm |
| L | Up to 21.7 in / 55 cm | 19.7-37.4 in / 50-95 cm |
Fit note: If one measurement falls outside a row, do not choose by the other measurement alone. Recheck the fit or ask for help before use.
