My dog, Ace, has been whining and crying for the past two days. Today, he refuses to lay down and mostly stands. Occasionally he sits. He also stopped eating, and has a poor appetite preventing us from giving him an aspirin. I'm not with him but my mom said she was able to feel his back okay but he won't lay down. He won't allow us to put on the body collar that wraps around his chest and bit my dad. My mom says a similar incident happened three months ago and he stopped after a few days. She thinks he will bite her if she touches the stomach. She says a vet will only give him stereoids and keep him in a cage for a few days. What should we do?
