Ermm...am I missing something? My healthy 12yr old dog has been fed Iams since he could eat dry food, per vet recomendation. He has always had a sensitive stomach and anything else will upset it.
IAMs is one of the lower quality dog food brands. It has more plant protein than it should have animal protein. 1st ingredient is down right a no-no, Chicken By-Product Meal. YUCK! Who wants to eat a mush that consents of chicken feet, feathers, beaks, and the like? Further down the list(not very far from the 1st ingredient) corn, wheat, barely, dried beet pulp, dried egg, yeast, salt, sodium hexametaphosphate, fructooligosaccharides(da heck is that?!), choline chloride(that sounds like something that should be in your pool O.O).
Take a look at the ingredient list of kibbles. In the whole ingredient list of IAMs, there was only 3 proteins listed. 1 of which is oils, which states has tocopherols(soy) in it.
PetsMart's Simply Nourish is a great mid-high quality affordable food. Lamb and Oatmeal formula would be great for the sensitives.
If you wish to learn more you can PM me and I can help you find an affordable higher quality kibble.....so as to not derail the thread entirely, ya know?
