New puppy, 8 weeks old, was on IAMS at the breeder, and so we've been feeding IMAS since we picked him up. We feel that there are other foods, with better ingredients - Fromm, for example. But his IAMS poops are great - very firm, practically ideal. Which leads me to believe that he digests IAMS very well. On the other hand - he may be digesting not the best ingredients. So, options are to leave things as they are, and stay with IAMS and good quality poops. Or try switching to Fromm, see what happens, and if poop gets worse - switch back to IAMS. Is the difference in ingredients worth switching? Is puppy food something that we can apply trial-and-errror method to, or better to stay with something that seems to work? Maybe better ingidients are more important than soft poops? All thoughts and comments greatly appreciated!
