What Size Collar & Harness for a Irish Wolfhound?
For an adult Irish Wolfhound, a XL collar and XL harness are the usual starting point, based on a typical neck of 51–66 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 51–66 cm · chest 81–102 cm · weight 48–70 kg
⚠️ Measure your dog — breed is only a starting point. A Irish Wolfhound'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: Sighthounds have necks as wide as or wider than their heads, so a standard buckle collar can slip off. A martingale or wide sighthound collar is safer.
Typical measurements for an adult Irish Wolfhound:
| Typical range | Recommended size | |
|---|---|---|
| Neck (collar) | 51–66 cm (20–26 in) | XL |
| Chest (harness) | 81–102 cm (32–40 in) | XL |
| Weight | 48–70 kg | — |
