What Size Collar & Harness for a Bulldog?
For an adult Bulldog, a L collar and M harness are the usual starting point, based on a typical neck of 40–51 cm and chest of 51–66 cm. But every dog is different — measure yours and use the two-finger rule before buying.
Collar: L · Harness: M
Typical neck 40–51 cm · chest 51–66 cm · weight 18–25 kg
⚠️ Measure your dog — breed is only a starting point. A Bulldog's build varies a lot between individuals, and a collar is a safety item. Measure the neck snug, add about 2-3 cm (the two-finger rule), and confirm against the specific collar's size guide before buying.
🐕 Breed note: Flat-faced breeds are prone to breathing strain; many vets recommend a well-fitted harness instead of a collar to keep pressure off the throat.
Typical measurements for an adult Bulldog:
| Typical range | Recommended size | |

| Neck (collar) | 40–51 cm (16–20 in) | L |
| Chest (harness) | 51–66 cm (20–26 in) | M |
| Weight | 18–25 kg | — |
