I'm getting worried about the little colt that was born here a few weeks ago. He seems to have one knee that is much bigger than the other and it is kind of an odd shape. He has had it since he was born, but I thought it might correct itself. It seems to almost have gotten worse. He can walk and gallop fine but when he stops, he kind of puts uneven pressure on the bigger knee and it wobbles. Here is a picture. What do you think it could be and can it be corrected if it is something bad? Thanks!
