Use a soft tape measure to measure your dog.
Since the Martingale must fit over your dog`s head, you must measure the largest part of your pooche`s head; from under the jaw around to the top of his head.
Next, measure the narrowest point of your dog`s neck, making sure that any extra hair is not adding inches!
Then, measure the midpoint of your dog`s next.
Choose the smallest size that will fit your dog comfortably.
