Me and my gf own a redfoot tortoise we have had him now for about 2 years. Each year we take him to the vet for a checkup. We noticed that since we had him he kinda walks on the side of his right rear leg as opposed to the bottom of his foot. He seems to get around just fine and it does not seem to bother him from what I can tell. Unfortunately I can't ask him. The vet never said anything because for some reason I never asked about it. My concern is do you think that this is something that could cause harm later down the road in his life? is there a surgery? I am wondering if it is just a birth defect? He is able to pull his leg inside all the way. It seems like he cant bend it at the knee like his other leg. I can take a picture it you need one?
