Hi,my 5 months puppy has diarrhea in the morning, then regular stool in the afternoon. He also has loud noises in his stomach and a lot of stinky flatulence. His appetite is normal but he sometimes is whining between meals just before he farts,like it hurts. Thank you for your help

Hi and thank you for using Petco Pet Education Center, formerly Petcoach. I am so sorry to hear that Toby has intermittent diarrhea and foul smelling flatulence. I would actually recommend taking Toby to see a veterinarian to determine he does not have intestinal parasites. This is incredibly common in puppies and could be a reason as to why this is happening. If he is negative for parasites, I would evaluate what food you are feeding him and how much/how often you are feeding him. I would recommend any puppy food from Hills, Purina or Royal Canin and feed according to the back of the bag. Good luck!
