I'm so sorry to hear he is having this problem. First off take him off of all food and let him just have water for a day to see how he does. Did you also know that even if you buy the same brand dog food all the time it doesn't mean it's exactly the same. Fact is, there is no way that dog food can be made exactly the same each and every time. Could be something different was added. Anyway, if he does ok for a day on water, then try him on some white rice and ground beef. Maybe you could switch him over to real food and avoid these types of problems. |
