It is very important to measure your dog correctly for a dog harness or dog collar. For best results we suggest using a cloth measuring tape or piece of string. When using string, mark the measurement on the string and then measure with a ruler for accuracy. Make sure the dog is standing on all fours and take the measurement at least three times for accuracy. The fitting should be snug and not tight, and also allow room for some movement.
Our collars are will have a sizing range eg Large Fits Neck 48cm-55cm. These readings are the inner circumference of the closed collar as it would be worn on your dog. This range is the range of the dog's neck circumference from the first hole to the last hole. If the dog is very young age and still growing we suggest purchasing a collar that is on the smallest setting ( FIRST HOLE) to allow for growth.
If the dog is an adult and fully grown we suggest purchasing a collar that fits the neck size in the middle range to allow for weight gains or expansion in the heat. For example if your dogs neck is 51cm in circumference - best to get the collar range of 48cm -55 cm which means the collar will fit on one of the middle holes with room for adjustment either way.
Here are some other "rules of thumb" when sizing a collar for your dog.
Please don't use other dog collar sizings to compare with our collars as our collars are padded and when closed the circumference is smaller.
