These decisions are so hard to make. When my Sherry had back/leg problems at 10 years old, I was told she had spondylosis. That's where there is a (sort of) bone spur or extra piece of bone that grows into a claw-like shape off of one of the vertebrae and eventually, it pinches the nerve. It doesn't always get to that point, but it can. It wasn't that bad yet and they told me not to do anything at this point. At 12, it started to get worse. They wanted to operate. I was not going to let them operate on a 12 year old. The recovery time would be terrible for her and there's no telling if she would make it. I didn't want to put her through it. They said if I did operate, I would need an MRI. THE $$$ were going up, up, up. I would spend anything on my pets, and believe me, I have, but I could not put her through the pain. So, I opted for holistic methods. I got her supplements like Cosequin and at 13, started bringing her to acupuncture every week. I drove over an hour every week and had to take off work one day a week to do it, but I did it. My baby was worth it. She was like a puppy when we first started going. You wouldn't believe the energy and she would run through the rooms. I was so happy, I cried. After a while, it wasn't working as well, but it was stable. At 14 1/2, she died of liver cancer. I believe the reason it appeared not to be working so well after awhile was b/c she had cancer, but I didn't know that yet. Whatever you choose to do, see what you can do naturally. See if there is an acupuncturist in your area that specializes in animals - don't go to one that just does humans. My Sherry was a different girl - just like a puppy. I didn't use any prescription arthritic meds b/c most either destroy the liver or make the stomach bleed. Try to stay away from meds like that and do research on the meds before you give them. In the meantime, I will keep you both in my prayers. I feel for everyone that has to go through decision-making times like these. It brings back sad memories. Good luck and look into that.
