Finding the perfect fit
There are 2 ways in which you can determine the right size collar for your dog.
Measure you dogs old collar (if it’s the right size). To do this, lay the collar out and use a tape measure from the outer edge of the buckle to the hole used. This will give you the correct size.
Measure your dogs neck. To do this, use a tape to measure how you want thecollar to fit around your dogs neck. It should have enough room so it’s not tight but not too loose that the head slips through. A rough gauge is to allow two fingers to fit easily under the tape whilst measuring.
