Dog & Cat size guide

For the comfort and safety of your four-legged friend, it’s essential to choose the right size collar and harness. Here’s the size guide for collars and harnesses for MAURICE dogs and cats.

What size collar should I choose for my dog ?

A collar for every dog

Your dog is unique. Even within the same breed, there are different sizes. Females also tend to be slimmer. To find the collar size that’s right for your dog, we suggest you measure his neck with a flexible tape measure and add a good centimeter to prevent it from being too tight.

A collar that allows a finger to pass between the collar and your dog’s neck is a collar that fits properly.

MAURICE offers 7 sizes of dog collar: XXXS, XXS, XS, S, M, L and XL.


For puppies, we recommend that you add 3-5 cm to allow for growth.


Once you have measured your dog’s neck, choose the collar size from the chart below:

SizeNeck circumference (cm)Collar width (cm)
XXXS18 – 231,3
XXS21 – 261,3
XS25 – 332
S31 – 392
M37 – 452,5 – 3,5
L43 – 512,5 – 3,5
XL49 – 572,5 – 3,5

For example, if your dog’s neck circumference is 41 cm, a size M collar with an adjustment range of 37 to 45 cm, will fit your doggy.

If you hesitate between two sizes, select the larger one.

What size harness should I choose for my dog?

The Y-shaped dog harness is a leather harness with an ergonomic design suitable for small and large dogs.

MAURICE has designed and developed 5 sizes of dog harness: XS, S, M, L and XL.

To find out which harness size to choose, we recommend you measure your dog’s chest (A) and belly (B). Here are the measurements for each harness size, along with a few examples of dog breeds, as a guide only. Every dog is unique, and every dog has its own harness! If you have any doubt, please send us a message.

What size collar should I choose for my cat?

A collar for every cat

As with a dog, a collar must be perfectly adapted to your cat’s morphology. It needs to be wide enough to avoid constricting your little feline’s neck, but not too wide either, as this could hinder your cat when out and about.

Measure the circumference of your cat’s neck to confirm that the chosen size is correct. We recommend wrapping a flexible tape measure around your cat’s neck. Then add 2 to 2.5 cm to the measurement to obtain your cat’s neck size.

MAURICE offers three sizes of cat collar: T1, T2 and T3.

SIZE T1 is perfect for kittens and small cats (alley cats, rex, scottish fold, abyssinian, sacred of Burma, siamese, singapura, sphynx) with a neck size of 18 to 23 cm.

SIZE T2, the standard size, is suitable for young cats of large breeds (british shorthair, ragdoll, norvegian and maine coon) and medium-sized adults (alley cat, american shorthair, bombay, sacred of burma, bengal, persian, russian blue, scottish fold, toyger and siberian) with a neck circumference of 21 to 26 cm. If you’re in any doubt about which collar size to choose, please don’t hesitate to contact us.

SIZE T3 is ideal for adult cats of large breeds (british shorthair, ragdoll, norvegian and maine coon) and large adults (alley cat, american shorthair, bombay, sacred of burma, bengal, persian, russian blue, scottish fold, toyger and siberian) with a neck circumference ranging from 26.5 to 31.5 cm. If your T3 cat collar size is too small, please write to us. We manufacture certain models on request.

Once you’ve put the collar around your cat’s neck, make sure it’s not so tight that it hurts, nor so loose that it snags easily. To ensure that your cat collar is correctly adjusted, leave a space equivalent to a finger or even a finger and a half between the collar and your feline’s neck. If your finger slips through easily and the collar stays in place, your collar is properly adjusted.
