I have a 4 year old Pom/mix. two years ago she had patellar lextion surgery on her left knee. Then 12 weeks ago she had her right leg done. She was healing good, up til a week ago. Now she will be laying down and jump up in pain, she don't want to walk at all, when she does walk she will hurry up and sit down. When she does walk her tail goes in a circular motion. But my vet has taken x-ray, ran her urine twice, blood work, squeezed her anal glands, and has went over her with a fine tooth comb. Every test has come back great. So he tired and anxiety med that didn't do anything. So he was clueless, so I took her to another vet to see what they thought, they ran test and also can't find anything wrong. But I can't handle watching her in pain like this, I'm almost to the point of having her put down. I already have $7,000 dollars into her, and my love for her is priceless. I just don't know what to do.
