Oh man, that's really too bad to hear, Carl. About the euthanasia, I would really say just use your own judgement for something like that.

I had a cocker spaniel from the moment I was born until I was 15. He grew up with me and all that. Well, for a couple weeks straight he completely ignored his food bowl. He would go over there for water, and that's it. The weird thing was, he would still ALWAYS get so excited when we would go outside to put more food in his bowl, almost like it was just a routine for him, but he didn't really know why he was getting excited over it. Sure enough, we took him to the vet and he had progressed stomach or colon cancer. I knew what had to be done, and my dad gave the vet the okay, because he knew he would just end up dying in our backyard from the cancer; and I didn't want him to suffer.

So, like I said, just use your judgement. To be perfectly honest, I see it all to often a dog that looks half dead (I'm not saying that's what your's looks like, I haven't even seen it), but the family is keeping it just because it's their "family dog". That's when it's sad to me.

Good luck on your decision, Carl.
