Thank you for submitting your question regarding Choco. There are a variety of different parasites that can affect young puppies. One deworming medication does not typically kill all possible parasites. It is worth having his veterinarian perform fecal testing to ensure parasites are not contributing to his diarrhea. If this does not help, then diet may be the cause. You can consider a different puppy formula. I hope this information helps!
