Measure around your dog’s neck where their collar naturally sits. Pull the tape until it is snug but not tight. A good rule of thumb is that you should be able to insert 2 fingers between the collar and your pup's neck.
Measure your dog's neck with a sewing tape. Or wrap a string around your dog's neck and mark the string, then measure the length of it with a ruler or tape measure. Or remove your dog's current collar and stretch it out flat. Measure the length the collar is being used.
