Dysplasia, one of the biggest reasons the USAF prefers Belgium Malinois o Shepards. I'd love to adopt that fella, but the dysplasia is only going to get worse and there isn't much you can you for it. Surgery is a short term fix. Usually, Sheppards have serious hip dysplasia issues. First time I've heard of one getting elbow dysplasia.

I used to work with the K9's @ Peterson AFB a bit... I was "wrap certified" to be the bad guy the dogs would attack. Those dogs certainly earned my respect.
