Puccini fractured his elbow and the vet put a very tight splint on it. They told us to come back in two weeks, but after 10 days, we smelled a horrible odor coming from his leg. He had three infected sores from the tight splint, so we did some research and found this custom brace. He is able to walk with it while his leg heals, and we can take it off when he's in his bed. I am so thankful for this brace. I truly believe it saved Puccini's leg.
