I just started switching Lola to Blue Buffalo puppy from eukanuba. The vet said to do about 25% new food. I think I did about 20% the first day. She ate all of the new food instead of the old as well. Then that evening she threw up and two days later had diarrhea even though I reduced it to just a few pieces. She has been fine ever since. I am going to keep slowly introducing it over the next month I think. |
