My older girl Hope has always been the skinniest when comparing her to her companion Casiss. But now that she is older she looks a lot worse. It's not bad enough that you can see ribs but you can definitely see she is not in healthy shape. I posted pics of her on a different thread to get her coloring so if you can find that maybe you can see how skinny she is. I'm not sure if you can though.I just worry about her and wonder what it might be. I'd go to a vet if I knew it was something more than just elderly weight loss. Any help and advice is appreciated.
