Just got back from taking my 15 year old dog, Buster, for a final vet visit, he didn't come home. It is hard. I probably waited too long, but he seemed to be enjoying himself to the end. It became obvious that he had cancer, bad, as in stage 4. The doc gave him some prednisone in hopes it would help, but it didn't. Still had an appetite right to the last, but was loosing weight and when I got home from work today he was too weak to get up. Me and my boy put him on a sheet, gave him a drink of water, and carried him out, petting him and talking to him the entire way. It was obvious he was eating the attention up. We kept this up even after he got the injection. He dropped like he had been clubbed, I suspect he was barely hanging on. There is no doubt I did the right thing, but it is hard. He's going to be one of the people I want to meet when my time comes.
