Easy Sizing: Measure your dog s paw width for the best fit weight is only a secondary guide. Size 6 fits paws 2.55 inches wide and dogs 52–68 lb. Durable rubber soles give dependable traction and shield paws from rough, hot, cold or salty surfaces. Double hook-and-loop straps lock each boot in place yet peel off quickly when the walk is done. Tough water-resistant fabrics stand up to snow, rain, sand and summer pavement, wash after wash. Pick from bright, solid colors to give your dog protection with personality.
