tehe, someone got info from my post! I feel special
Anyway, A lot of those foods are meant for adult dogs, you dont want a puppy to eat to much protien(no one is sure or not if it is even good for adult dogs!) because of their develpoing, and in turn sensative digestive systems. As far as foods go, I would also reccomend Wellness puppy. Its what we will send all of our puppys home with! Personally, I would try to stay away from pro-plan, the second ingrediant is corn-glueten meal. While it wont necisarally hurt your puppy, all it is is a filler, and dosnt offer nutriotial value......they dont digest it, and what goes in comes right back out, which wont necisarally help your problem
I would try to stay away from any foods with corn or wheat(rice is fine, but actual wheat, especually wheat gluten you want to stay away from) Like I said, I would reccomend Wellnes for Puppies, and if not wellness Inovva puppy.
I hope that helps!
Oh, and if you have more than just the puppy, and the wellness/innova seems a little pricy, there is also Canadae. Its not quite the quality, but it is still a good food, and puppies, adults, and senoirs can all eat the same food, making your job a little easier
