Don Lorino
Find the right size
Measure your dog or cat at home and use the tables as a quick guide. Always check the measurements on the relevant product page before ordering.
How to measureStep 1
How to measure
Use a soft measuring tape and let your dog or cat stand naturally. Keep the tape close to the body without pulling it tight.

Neck circumference
Measure where the collar normally sits. Use the actual measurement and compare it with the range in the table.
Tip: Measure twice and position the tape in the same place each time.

Head circumference
Measure around the widest part of the head, in front of the ears and beneath the jaw. This measurement is important for products that slip over the head.
Check: The product must pass over the head without being able to slip off.

Chest circumference
Measure around the widest part of the chest, usually a short distance behind the front legs. Keep the tape flat around the body.
Avoid: Measuring directly in the armpit or too far back across the abdomen.
Step 2
Three things to remember
Measure close to the body
The measuring tape should sit against the coat without feeling tight or leaving a large gap.
Compare with the range
Your dog’s or cat’s measurement should fall within the stated size range.
Check the product
The tables provide an overview. The measurements on the relevant product page always apply when ordering.
