This product has been a lifesaver. My senior dog (yes dog!) had a failed Achilles’ tendon repair surgery and she is permanently disabled with a “floppy” flat-footed stance. No product exists in the canine market shaped to fit her leg in the L-shape we needed. All the splints for dogs are to straighten their legs - which I learned the hard way, causes complications and pressure sores. This bootie gave her her life back, literally! She doesn’t have to hobble around and we were able to go on (short) walks again. We got the smallest size and it fits her perfectly and doesn’t cause any sores or pressure wounds. (55lb German Shepherd/chow/mutt) We never take it off, except to change the dressing for an open wound she has on the joint of her heel (from the dog splint we first used…ugh). I have bought two of these this year so far and will continue to purchase more as needed. We use the older one for yucky weather and backup when this one needs washing. My only complaint is that the Velcro straps on the interior loose stickiness to the bootie fairly quickly (after less than two months), and we aren’t taking it on and off a lot, but that’s an easy fix with some tape. The traction wears off the bottom too, but that’s not really important. This isn’t meant to be a forever bootie for kids, so of course things will wear over time. Side bar: You all should consider getting into the market for dog splints because it is seriously lacking and so many people and veterinarians have been impressed with my creativity around this! Haha. Thanks again, MiniTrax walker is truly the best!
