How do I find the correct size for my dog?
How to Measure Your Dog:
What you’ll need: a soft tape measure (or string + ruler), a pen, and your dog standing naturally.
-
Neck circumference (for collars & harnesses)
-
Wrap the tape around the base of the neck where the collar sits.
-
Keep it snug but not tight and use the two-finger rule (you should fit two fingers comfortably under the tape).
-
Note the measurement. If between sizes, choose the size where your dog sits near the middle of the collar’s adjustment range.
-
Chest girth (for harness fit)
-
Measure the deepest part of the chest, just behind the front legs.
-
Keep the tape level all the way around. Record the number
-
Between sizes? Go up one size for growing pups or very fluffy coats; otherwise choose the option where your dog sits in the middle of the adjustment.
Pro Tips
-
Measure twice to be sure.
-
For long-haired or double-coated breeds, add 0.5–1.5 cm if you like a looser fit.
-
Weight is a helpful guide, but measurements are most accurate.
-
Replace any collar that fits on the very last hole—your dog has outgrown it.
Safety Check
-
After fitting, ensure you can slide two fingers under the collar.
-
Check weekly for puppies (they grow fast!) and after grooming.
