What Size Collar & Harness for a Cockapoo?

For an adult Cockapoo, a S collar and S harness are the usual starting point, based on a typical neck of 28–38 cm and chest of 43–56 cm. But every dog is different — measure yours and use the two-finger rule before buying.

Typical neck 28–38 cm · chest 43–56 cm · weight 6–11 kg
⚠️ Measure your dog — breed is only a starting point. A Cockapoo'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.
