If your dog is still growing or is at the top of a range, sizing up is usually best.How to measure
Two easy ways to check the fit.
Measure your current collar
Lay your dog’s collar flat. Use a ruler or flexible tape to measure from the start of the leather or fabric at the buckle end to the middle of the hole normally used.
Measure your dog’s neck
Wrap flexible tape snugly around the widest part of the neck. If you do not have a tape, use string or ribbon first, then measure it with a ruler.
Still unsure?
Choose the larger size if your dog is between sizes.
The collar should be secure enough that it cannot slip over your dog’s head, without restricting breathing or causing discomfort. You should be able to fit two fingers comfortably between the collar and neck.
