My dog is a 12 YO Golden and he is not doing too well. He's never been over 5 lbs overweight, lean and wiry and light footed has been his usual look. He weighed 75 last Nov, and a month ago he was down to 65. I asked the Vet, 'so what may be causing it?' as thinking maybe something we should check for. She goes "don't know". I think he is getting near that tipping point where it can all go down hill health wise very quickly, as is I'm not sure if he'll make to spring. So this is a hail Mary as perhaps others have encountered this too and could give me some insight if anything can be done to stop the atrophy process. Maybe do a liver function (or similar) test and more importantly if anything drug/nutrition wise which can stop/reverse the muscle atrophy process. The last time I had a dog loosing this kind of muscle mass was it had cancer and had lost 10 lbs in 2 months time. 3 months later he was dead from that damned cancer. The vet didn't think it was cancer being the process was so slow. So looking for a potential what is causing it, and much more importantly - a remedy. So what is the Refuge brain trust's insight on this?
