OK...this is the ***** that when she was a puppy went lame all of a sudden and after a couple days of not improving- took to vet. Found a swollen tick in her ear at the vets. Started on antibiotics, cleared up lameness. Last winter, she went off her feet badly and again put her on antibiotics, she recovered for the most part, but she also had gotten into a fight with her kennel mate and I think she has permanent damage in her back from that. She still had a bit of stiffness in movement and this ***** was one of my best movers and had healthy hips on xray at 3 yrs old. Now, I noticed she was going lame again day before yesterday. Thought the cold may be bothering her. The day warmed up yesterday and she was not moving much better and she was tending to spread her rear legs out when moving, so brought her back up for house time and examined her closely. No signs of squabbles but her hind legs are definately swollen from the hock down. She does not have a fever. This ***** is also coming into season and I was planning on breeding her for her second and final litter. Ideas? Suggestions? My vet is still out from his back surgery.
