These boot fit well and have stayed on fairly well. My older large dog had foot surgery so these worked well to cover his dressing and added padding and protection. Gave him better traction on the hardwood floors since this has been a problem for him with his weakening back legs. He did pull one off and start to chew it so took them off the front feet and use mainly on the injured foot. Occasionally he gets one turned around but they still stayed on. Pleased with this product.
