when shes taken out of stable in the morning she seems slightly lame but after 5 min it disappears and is very stiff in her hindquarters then we put her on the waker and she seems to walk it off, you might get 3or4 days when shes ok and then were back again where we started. Dan
Good Morning Dan and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question. I am so sorry it has taken so long to get back to you....
My fear for your mare is that she is suffering from a Rhabdomyolisis due to increased Lactic Acid in the muscles of the rear legs....Tying UP Syndrome. LINK
This can happen even in fit horses that are not supplemented with electrolytes. The next step is to have blood work done on your mare, Dan, after being exercised to see how much muscle damage is being done. This could be due to a hereditary issue and often electrolyte supplementation will solve this for your mare. There are some that cannot metabolize well enough making them not good for a performance horse. I was involved with long distance endurnace races and saw this often. With our horses, we would give electrolytes every 10-15 miles to prevent this situation...your mare may require this, Dan.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, XXXXX XXXXX
