-
Neck
Measure around the base of your dog's neck where the collar normally sits. Keep the tape snug but comfortable, allowing room for two fingers between the tape and neck.
-
Chest
Measure around the widest part of your dog's chest, usually just behind the front legs. Keep the tape level and snug but not tight.
-
Spine Length
Measure from the base of your dog's neck (where the collar sits) to the base of the tail. Keep your dog standing in a natural position.
-
Stomach
Measure around the smallest part of your dog's stomach, usually just in front of the hind legs. Keep the tape level and snug but not tight.
