We feed it to 2 of our dogs, and the puppy gets the Purina ONE puppy food. Lately (the past week or so?) our dogs have been vomiting. Last night, my senior dog had explosive diarrhea and vomiting. I thought it was from a Rimadyl I gave him on an empty stomach (I wasn't thinking) but now I'm wondering if it's the food. Both dogs have been vomiting, and the puppy vomited last week when he ate some of the Purina ONE. I am trying to figure out if it's a virus or the food. We've fed this food for several years, and haven't had any issues, so I'm not sure what it is. I didn't see any recalls for the food. We're going to pick up a new bag from the store and see if it stops the vomiting. Is anyone else feeding it? Any issues?
