Hello and thank you for reaching out to Pet Coach. It is good that your puppy is still playful and drinking. Diarrhea in a puppy this age is very common as a direct cause of: parasites (even though a dewormer was given), abrupt change in diet, or viral infections of the intestinal tract. It is important that his feces are tested for parasites and possible viral infections (depending on his vaccination status) by your veterinarian as soon as he can be seen. Your veterinarian will also be able to provide medications for the diarrhea as well. Make sure you keep him eating and drinking, and continue to monitor carefully.
