ADVICE

My 6 month old puppy keeps going through moments where his poop will be normal and then around bed time he will have diarrhea and start throwing up? I don’t know what to do. I have him tums he seems okay for now. Also!!!!! When I’m gone I put up gates and he knocked a gate over and pooped all over my carpet, I used Lysol in a carpet shampooer and puppy spray (get rid of odor) and I still smell it. I’m not sure if it’s him or my wet carpet smell. What do you do to get rid of odor?
