Cant really be much help on health issues between foods, but cainan seems like his favorite thing IS to poop! almost everytime i let him out he poops. Yes he eats eukanuba but he seems healthy. doesnt get sick, really happy go lucky puppy, fecal sample is A-OK, everything seems perfect...just poops alot!
I look at it as it's better to have him going too much than not at all!
