My handmade vest/harness are light weight and very comfortable for your dog. Fully lined and each one is a little different from the rest. They fit the smaller breed of dog from puppies to Yorkie to Chihuahua and Shih-Tzu’s. Check out the ones I made with Pink Ribbon fabric for Breast Cancer awareness. Sizes: Extra Small (3-5 lbs.), Small (5-8 lbs.), Medium ( 8-11 lbs.) and Large (11-14 lbs.)
