Extra small for our little friends, like Piper, who is a mini dachshund. She weighs 8lbs.
Our small size fits most small breeds, like Goose, who weighs 15lbs.
Our Medium size fits Dingo, who weighs 40lbs.
This is our most popular size! Our large fits Sulley, who 55lbs with a lot of fur. It also fit our Doberman, 98lbs but sleek. When in doubt, I would order a large.
Extra Large works best for our bigger breeds who have a lot of fur, like Mac, a german shepherd. This is also the size for most golden retrievers.
