Dogs just aren't meant to wear shoes. This was my last ditch effort of finding a shoe to ease my dog's 8-10 chronic paw condition. I have wasted what some would say is too much expense at trying to find comfortable shoes. Once I did ok, but the manufacturer changed design. These thera paw boots look good on paper but he cannot walk in them, except clumsily and tightening every ten steps. I had high hopes, but these are advertised to be worn 24 hrs with a strap and velcro flaps that add pressure to his already injured paw.
