What Size Collar & Harness for a Saint Bernard?
For an adult Saint Bernard, a XL collar and XL harness are the usual starting point, based on a typical neck of 56–71 cm and chest of 81–102 cm. But every dog is different — measure yours and use the two-finger rule before buying.
Collar: XL · Harness: XL
Typical neck 56–71 cm · chest 81–102 cm · weight 54–82 kg
⚠️ Measure your dog — breed is only a starting point. A Saint Bernard'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: Measure with the fur pressed flat, then consider sizing up — a thick coat needs extra room and can hide the true neck size.
Typical measurements for an adult Saint Bernard:
| Typical range | Recommended size | |

| Chest (harness) | 81–102 cm (32–40 in) | XL |
