NeoAlly’s Rear Leg Metal Spring Support Dog Braces are designed to provide your canine companion with rear support. They are designed with metal springs for extra powerful support that can also be easily removed depending on the condition of your canine companion. Even if your dog only has an issue with one leg, often the other leg could be at risk for getting hurt due to the imbalance caused by the injured leg—that’s why every purchase comes with two braces! Plus, they are made from a breathable, flexible and supportive neoprene material, so your pup doesn’t have to suffer from rubbing or pinching.
