Sometimes it's our own faults that our companions are lame. While usually avoidable, hip dysplasia puts an end to many dogs' careers at too young an age. Inattentive breeding practices and injuries/accidents can cause the hip issue, and often we, as owners, don't realize something is wrong until we see our pooch limping. But just as often we don't know what we're looking at either. Is Fido just sore from a workout? Getting old? Or is it hip dysplasia or did he blow a ligament? It's sometimes tough to tell. But here's a little tool that might help you diagnose whether or not you need to get to the vet ASAP or not.
