Good fit is key for optimal wearing comfort. If you already have a good fitting collar, measure it from the buckle to the adjustment hole, and refer to the flat collar size chart for the size.

If you measure the neck size of your dog, always make sure that you fit about two fingers underneath the collar for comfort.

In between sizes? We suggest you take the bigger size!

The higher number should be big enough so that it fits over your dog's head. The lower number should be tight enough so that it does not slip over your dog's head.
