Help! Does anyone know what this might be? Hes never been able to walk the best even when I first got him from the store... he is a crested cayuga so I figured that was one of the reasons his walk was off... but he is a great swimmer, he absolutely loves the water. Well just this week his leg got swollen and he can not put no weight on it.. and he also got sore like things on his foot. He still eats and drinks like a champ. Any idea what this could be?
