Dog Collar Sizing

Step 01

Measure your dog’s neck

Wrap a soft measuring tape around the place your dog’s collar naturally sits. If you do not have one, use a piece of string, then lay it flat next to a ruler.

Keep the tape comfortably snug—not tight. You should be able to slide two fingers underneath.

Step 02

Match the measurement

Wrap a soft measuring tape around the place your dog’s collar naturally sits. If you do not have one, use a piece of string, then lay it flat next to a ruler.
