Choosing the right size dog boots for your puppy is simple: measure the widest part of the paw while your dog is standing. Size 1 fits paws 1.10 inches across and dogs 2.2–6.6 lb Size 2 fits 1.29 inches and 6.6–11.0 lb Size 3 fits 1.49 inches and 11.0–16.5 lb. The boots are made from soft, breathable fabric that keeps paws cool in summer and warm in winter. A textured rubber sole gives anti-slip grip on hot pavement, icy sidewalks, sharp stones, broken glass, snow, rain or slippery floors. Reflective touch-fasten straps adjust in seconds, stay secure on walks or hikes and shine under headlights for safer night outings. The boots shield hardwood, car seats and visitors from nail scratches, reduce licking and chewing on wounds, and keep injuries clean during play or rest. Lightweight and flexible, they let dogs move naturally while turning every outing into a pain-free adventure.
