i took my dog to the Vet because she was having a problem with her right leg. They gave me some muscle relaxers for her wich seemed to help alittle. Every time she lays down and goes to get up from sleeping it appears that the problem is back. if you massage her leg and move it and bend it ,it doesn't appear to hurt her yet she still seems to act as though the leg is bothering her.

Please let me know what could possibly be wrong with her leg.
