How to Measure Your Pet’s Collar Size

The first thing you will need is a measuring tape. If you do not have a measuring tape, you can also use a string or a long piece of paper, which you can then measure with a ruler. Then, follow our two-step guide.

Step 1 Measure around your pet’s neck, making sure it is neither too tight nor too loose. We recommend leaving enough space for two fingers to fit comfortably between the collar and your pet’s neck.

Step 2 Once you have the measurement, check our size chart for your pet’s collar size. If your measurement falls between two sizes, pick the larger size.

If a collar is too tight, it can cause skin irritation and hair loss. It is important to ensure that the collar fits your pet comfortably. We recommend avoiding prolonged use of collars. This applies to all collars, regardless of the material.

If you crate your pet, we recommend removing their collar before doing so. This prevents the hardware of the collar from getting stuck on any metal part of the crate. If your pet is prone to pulling on the leash and collar with extreme force, there is a possibility that some parts of the leash and collar equipment might break.

If your dog loves snow, water, or spends a lot of time at the beach—or outdoors in cold weather—we recommend customizing a collar. We offer a black plastic buckle with a secure lock. It’s super strong, more flexible and handles harsh environments way better than a steel buckle.
