Finding the right fit for your cocker
Working cockers, show cockers, wriggly puppies and well-fed seniors come in all sorts of shapes. Two minutes with a tape measure saves a lot of returns — here's how.
How to measure your cocker
Use a soft fabric tape measure (a piece of string and a ruler works too). Measure with your dog standing, ideally after a walk when they're a bit calmer — and keep a treat in your other hand. Feathering adds bulk, so keep the tape snug against the body rather than on top of the fluff.
- 1
Neck
Wrap the tape around the middle of the neck, where a collar naturally sits. Add two fingers' width for comfort.
- 2
Chest (girth)
Measure around the widest part of the ribcage, just behind the front legs. Cockers are deep-chested, so this is often bigger than you'd expect.
- 3
Back length
With your dog standing square, measure from the base of the neck (where the collar sits) to the base of the tail.
- 4
Head
For snoods, measure around the head just behind the ears and under the chin.
- 5
Sleeping length
Measure from nose to base of tail while your dog is lying stretched out, then add 15–20cm.
Between sizes? Choose the larger size and adjust it down.
Growing puppy? Re-measure every couple of weeks — cockers grow fast until around 9–12 months.
Show vs working: show-type cockers are usually heavier-boned and broader in the chest.
