The only side effects I'm seeing since feeding Stogie Innova EVO for several days now are, he gets very tired soon after eating. Like humans do after eating a big meal? I'm assuming thats his system adjusting to processing the denser protein in the Innova EVO vs the Purina Beneful he was eating before? And he's got gas!!! OMG does he have gas. Hard to believe that much stink can come out of a tiny 8 lbs weenie dog. Are these symptoms normal after abruptly switching his food? (beneful one day, innova evo the next)... or are these signs of something I should be worried about?
