Annie: I know EXACTLY what your going threw, i'm having something similar with my dog Rufus. He is about 16ish now, and there is many signs of ageing. I took him to the vet like 2 days ago for his shots, and asked advice about whats better from him, and if hes in pain. If it helps heres what she said "If he's eatting regularly and having regular bowel movements, and not having strange behavior it should be fine." Does it seem like your dog can't get comfortable? Or maybe its painful to laydown?? I kinda thought that with my dog too, she sugested I give him 1/2 a bufferin asperin (has to be bufferin) a day, and to go to 1 full one if necessary, and that its probably arthritis, and he might be in a a little pain..so the buffrin should cope with that. I hope this helped a little
