Well, to cut a long story short, Odi had Onion Toxicity. I had no idea that onions can kill dogs. His daddy cooked up a heap on the new BBQ then put them in his food all week. The onions made him anemic (dropped his red blood count). Getting to the bottom of what was making him anemic was the problem. If it had of been his heart medication we would have had issues. Anyway, Odi may forgive his dad for trying to kill him, but he is definetely on the mend!
