My dog hasn’t eaten anything for days and I’ve tried everything. He stopped eating his chicken and soft food, he won’t eat any vegetables that I try to give him, he’ll barely lick peanut butter, and refuses to have treats. I’m literally trying to feed him bacon at this point, but I don’t think it’s gonna do anything. He’s 15 and my dad is saying he’s probably dying. This has all progress over a week.
Then you need to talk to a second vet. They’re right, he’s an old dog and probably toast, but at the very least you should help him be comfortable, whether that’s putting him down or just painkillers.
