The measurements are the dimensions of the actual product, not of the pet they fit. After measuring your pet, make sure all measurements fit within the following dimensions (with a little room to spare in the chest and neck).

Measuring Guide:

Back: Measure length of pet's back from the base of the neck to the base of the tail.
Neck: Measure the circumference of the pet's neck for a snug, not tight fit.
Chest Girth: Measure the broadest part of the chest and add 2" for ideal fit.

Note: If the dog has a stout build, select one size larger.

Clothing Disclaimer: Some clothing sizes may not be available at the time of purchase. We will contact you about a possible size replacement. We can also email you when the product is available again.
