The blood work indicated the dog was also in renal failure. Some of this could be acute from a possible obstruction, but there could also be a chronic component because she had weight loss and we knew some of these issues had been going on awhile. The owners declined referral to a specialty center so we did what we could.
We performed surgery to remove the stones, started the dog on a high rate of IV fluids and appropriate medications. Now we are just waiting to see what kind of response we get.
Here are the stones post op. FYI this was a small breed dog.
