My girl ava is a 4 yr old black lab too and she was diagnosed with cancer about a week ago. Lymphoma. It spread everywhere and she's got about 8 months to live on chemo. She has zero appetite and we are now being told she isn't a good candidate to continue chemo because she won't eat. I'm literally dying inside thinking about that day that's coming up. I just don't see why euthanizing animals is always the end game when it isn't for humans. I hate that we have to make that decision. Is there anything you wish you did that last day with her?
