We've been feeding our pup (15 weeks) Innova (puppy large breed). His coat is beautiful, shiny...his dandruff is almost gone... He loves the food ... I'm wondering for those of you who feed you gsd's Innova - do you notice lethal air biscuits...and soft (not runny) stools? I'm wondering if there is anything that we can do to minimize the gas. There is nothing like waking up in the middle of the night..surrounded by gaseous fumes. We're thinking of changing the food but if this is simply part of puppyhood - we'll deal with it .
