I am not sure about Nutro (I have heard Nutro Ultra is good though) because I personally have only bought the Innova Puppy Dry and have changed to Canidae because my puppy didn't like Innova after 2 bags and Canidae is much cheaper than Innova with the same quality but what I know is, sometimes when you change food, it does take time for their tummy to get used to the new food. Give your puppy 2 weeks and if the situation still persist, maybe the food doesn't agree with his tummy. Sometimes it is not so much of the quality of the food. Like human, it really depend on the individual dog and what their tummy is okay and not okay with. |
