Why my 5 month old black lab always gets diarrhea, especially in the evening? Thanks

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Causes of diarrhea are: intestinal parasites, viral or bacterial infections, dietary discretion, food allergies or food sensitivities. If Fred is up to date on vaccines and has had a fecal sample run recently then I would suggest a probiotic and consider changing his puppy food to a novel protein diet. The most common allergic protein in dog food is chicken. I would suggest changing him to duck, venison or a fish based diet. Eliminate all human table food and all treats that are not made up of the new protein. Diet trials can take 2-3 months to see if they work. I like Purina Fortiflora for a probiotic. If a fecal has not been run by your Vet, drop one off to have it checked. I hope this helps and good luck!
