Food & NutritionWhat's the best puppy food for a sensitive stomach: Science Diet or Honest Kitchen?
As you've experienced, diet changes can certainly cause some changes in stool volume, and for some dogs, can cause a bit of vomiting and diarrhea. When it comes to the countless brands of dog food on the market today, it's overwhelming to pick one for your pup. I recommend brands that have been formulated by a board-certified veterinary nutritionist, are manufactured in their own facility (less cross-contamination that facilities that manufacture numerous formulations), conduct AAFCO feeding trials, and meet WSAVA guidelines. When it comes down to it, the brands that meet those criteria include Hill's Science Diet, Purina, Royal Canin, Eukanuba, and Iams. As a result, I would recommend switching Lilly over to the Science Diet puppy food. Just remember that anytime you switch foods, be sure to do so by gradually mixing the old and new foods together over a 5-7 day period. I hope that everything goes well!
