Ruffwear XL Polar Trex Dog Snow Boots and drawstring carrying bag Excellent traction with rubber soles on the part of the boot that the dog actually walks on. My dog Winston is 90lbs, really big feet and these fit perfectly. Keeps their feet protected from the ice, snow, rocks, the chemicals put on roads to melt ice(which can be toxic to your dog) like magnesium chloride. Also protects from hot pavement in the summer, stickers and burrs, and repetitive running on rough surfaces. Winston wore them hiking in Colorado and has worn them in old age to help him stand up on slick surfaces with arthritic joints. Sanitized, great pre-owned condition, no tears, no stains, no signs of wear. One set of 4 boots and bag. I'd like your pup to enjoy these as much as Winston. I'll consider any reasonable offer.
