I would not recommend Pepto bishop for diarrhea, as the ingredients are often not well tolerated in dogs. You can feed some canned pumpkin or boiled chicken and rice to see if that helps but if it's not improving she may need to see your vet for treatment.

    It sounds like your dog has a case of colitis, or an inflammation of the colon, resulting in an increase in the volume and frequency of stools. 

 Colitis can be caused by many different things. Some of the more common causes include intestinal parasites, dietary indiscretion, food intolerance, irritable bowel disease, pancreatitis, a foreign body/blockage and viruses. 

 Because Max is so young I would recommend taking him in to your vet to be examined. They will likely want to check a stool sample and may recommend some lab work, a dietary change, and/or antibiotics. 

Until then, continue feeding a bland diet like you are. As far as giving Pepto, I usually do not recommend it. It can mask the problem causing the diarrhea which could make it take longer to get Max well. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

    Unfortunately it is illegal for us to advise doing this without seeing Raider in person. In addition, this may be the wrong treatment for the cause of his diarrhea. It could be caused by intestinal worms, GI illness, a sudden change in diet, eating something rotten, or a foreign body. I'd take him into a vet in the morning to have this treated.

    Unfortunately it's illegal from us to recommend using an OTC medication such as pepto bismol without seeing Penelope in person. I strongly recommend having her seen by a vet today if possible. It's never a good idea to use an OTC human medication on a puppy unless specifically prescribed by a vet. Her vet can let you know if this is safe or not, and can treat her diarrhea. Best of luck.
