So last week my dog started limping, It was pretty bad when she first woke up in the morning but seemed to be not quite as bad once she was up and walking for a while, but she still had a limp. I thought she might have something stuck in her foot but couldn't feel anything and it didn't seem to be getting any better for a few days so I took her to the vet today. He told me it looks like arthritis, I didn't feel like he was 100% sure. I asked about x-rays and he said normally it won't show anything up. He recommended doing 4 pentosan polysulphate injections over the next 4 weeks and trying some different medications. My dog doesn't really go well with vets and was pretty nervous/freaked out so I said I try the medication first and if there's no change I'll come back for an injection. The 2 I bought were powders, joint guard and 4Cyte Canine and he said I should also give her fish oil. I feed her what is probably fairly low quality wet food which I plan to change but I do feed her decent dry food. Uup until the limp I walked her daily. He checked her overall, teeth, gums, temperature etc and all was fine. I'm just not sure what to do from here, she's 9 years old and I've never had any problems with her except for the odd ear infection which I'm told is because she has very narrow ear canals. I asked whether I should still walk her and he told me short walks are fine. Anyone who has had any experience with this do you recommend anything different? Should I go to another vet for a 2nd opinion, should I have gotten those injections? She's a 9 year old malamute x shar pei and I've had her since a pup, it just kills me thinking she is in pain when she walks and want to try whatever I can to help her. I'm doing as much research as I can but thought I'd ask here for any feedback I can take on, thanks.
