How old is the dog and what breed? A puppy can go cow hocked and manage to straighten as they gain muscle, particularly if they have a lot of rear "angle" (turn of the stifle), if that's the case swimming and running the dog on sand will help (don't over work a puppy, but allowing to play and run in sand and swim will help build muscle).
Does the dog move true when watching from behind, or do the hocks reach outside of the front legs? Many dogs will stack hocky and then will move true... if that's the case, she's probably just a bit weak in the rear, again, build muscle.
If the dog is truly hocky, depending on the severity of it, it can be a problem, as MRV has said. However, there are people who believe that a cow hocked dog provides more agility and power in the rear (for take off). I don't know if that's necessarily true, or at what point it goes from power/agility to "too much" and becomes a liability. But, I've seen a huge amount of hocky dogs in agility and in the field and it certainly doesn't appear to slow them down :)
