Certainly a variety of methods and probably one may work.
Since you say that the hips are going, have you tried other things for relief, such as Dasuquin supplement, Rimadyl for short term with concurrent liver monitoring, or even acupuncture?
She's been on the Cosequine for a couple of years now, and that made a BIG difference. At the time, I actually thought I might have to put her down, but after a couple of months of the Cosequine, there was a big improvement. The vet actually told me to up her dosage now. She's had Rimadyl for short durations when she's forgotten how old she is and over-exerted. I always have a supply on hand. He's still pretty adamant about not going to fulltime Rimadyl or other anti-inflamatory until there is no other choice.
The visit (annual) yesterday was actually kind of a wakeup call for me. He took about three times longer than he usually does talking to me about quality of life decisions and options. My big concern was that she's getting a bit of old dog bronchitis (as I learned from him, since I didn't know what it was), but he wasn't concerned about that at all unless it increases (he did x-rays).
His big concern was the way she walked, which I guess I don't pay as much attention to since I see it everyday. He said there's definitely a little pain there, even if I can't see it. I would have expected pain to be her really struggling to get up, or not wanting to at all, which was supposed to be my cue to myself on the quality of life decision. She only sorta struggles to get up on her hind legs, but she always wants to, and still likes to putter around the yard and stuff. Nothing at all that would cue me into any pain. But the vet said from the way she walks that she has at least slight pain while doing so.
Hence we're trying the Tramadol now. I still have no idea why she hates it so much. The freakin' Trifexis even my human nose can smell from 20', and it smells like pesticide (which of course it partially is). The Tramadol must have a really bitter taste to a dog's mouth. Her expression after I give her Trifexis is, "Gee, thanks pal!" Her expression when I gave her the first Tramadol was, "What the hell is wrong with you?!? Are you trying to poison me or something?"
I've never thought about accupuncture. I've seen a poster at the vet's for some kind of laser therapy, but know nothing about it.
Anyway, the visit yesterday made me a lot more cognizant about monitoring her condition to make sure I'm not overlooking anything, or worse, subconsciously overlooking her condition because I want to keep her around longer.
