Hi I have a question-has anyone else experienced soft stools and Or diarrhea frequently with their puppy?? I was told it could be a sign of a growth spurt as our pup is just 5 months old. He's had this off and on again diarrhea for a while now and we've changed his food and even put him on antibiotics which seem to intermittently help. We've even had him tested for parasites and worms with negative findings. Is it possible this is just a puppy thing? He is extremely playful and about 50lbs at 5 months so he is surely growing but I'm worried he isn't getting ample nutrients if he is pooping frequently and it is soft. PLEASE HELP!
