Corgi has started showing signs of what I think is early hip dysplasia. He is two and a half years old.
He's never been a very athletic dog and he has always been very stiff, but I never thought much of it. He has also always had a habit of dragging his back legs around when he's moving short distances, something I have heard other Corgis do as well.
When he wakes up from sleep, Corgi is very lazy and appears to be very stiff. When he runs, he looks hilarious like he is hopping around and almost looks like he is wobbling. He can not jump at all and never has been able to jump high. Also, after a long walk he will act like he's very sore and doesn't move well when we are done. He may walk a few steps and then sit right back down. Sometimes when he is playing with Buster, Buster will hit him too hard and I'll hear a whimper, and then Corgi will just sit down and not want to move around for a few minutes. In addition, Corgi can not sit normally (I don't know if this is due to the hip). When he sits, he always has to have his legs out to one side and can not tuck them like a normal dog. It almost looks like his spine is too long for his short body or something...
Corgi is relatively small and weighs around 25 pounds. He is definitely not overweight and he gets good exercise (2-3 short walks per day.)
Anyone have any input or suggestions on whether it is Hip Dysplasia and what to do about it?
