Charlie bought this for walking his Shetland Sheepdog, but he bought it twice and never used it. Suitable for: Miniature Schnauzer, Cavalier King Charles Spaniel, Shiba Inu, Beagle, French Bulldog, Bulldog, Corgi, Border Collie, Golden Retriever, Labrador Retriever, Bernese Mountain Dog, and other dogs. Total length: 66 cm (max) to 50 cm (min) Leg circumference: 64 cm (max) to 44 cm (min) Allows dogs with difficulty walking in their hind legs to walk easily. My dog has already had surgery, so I won't be using it. I'm offering it at a low price. Please give it a try!
