Thanks Stacy, she drinks no more than normal, her appetite is still normal although she is always begging. So probably always hungry but I have another dog so try not to overfeed + she always eats her share + not that of the other dog. No tests have been done so far as I'm reluctant due to her age as will commence the slippery slope to doom. She's happy + see no signs other than weight loss + change of fur colour. I suppose I'm looking for some insight before I consult our vet! She seems cachexic if she were human! Also I'm a people nurse!
