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 wide and dogs 2.2–6.6 lb. Size 2 fits paws 1.29 inches wide and dogs 6.6–11.0 lb. Size 3 fits paws 1.49 inches wide and dogs 11.0–16.5 lb. These soft, breathable booties keep paws safe from hot pavement, sharp stones, broken glass, ice, snow and rain. The skid-proof sole gives older dogs, puppies and adventurous hikers steady traction on hardwood, tile, sand or trail. Reflective straps tighten in seconds, stay secure all day and shine at night for safer walks. The boots also stop claws from scratching floors, car seats or guests, and they cover wounds so dogs cannot lick or chew. Lightweight fabric keeps paws cool in summer and cozy in winter, letting every pup run, jump and explore in comfort. We designed these shoes to help dogs live pain-free, happy lives because joyful pets make joyful homes.
