I am so impressed with the quality, fit, and ease of use of these boots. My 140#, senior malamute mix has begun to shuffle his back legs thus injuring his paws on our walks. We’ve tried a number of things and this is the clear winner. He slides right into them and is excited to do so as it means walk-time. They fit great and don’t slip off or twist. Great boots and tons of compliments as they are so dang cute on him. Thank you!
