This could be from parvovirus or intestinal parasites. Since he’s so small and young I recommend a veterinary exam and treatment. He could get dehydrated quickly and that can become life threatening. They will test him for parvovirus and check for intestinal parasite. They will probably give him fluids to prevent dehydration and medication to control the diarrhea. Usually if treated quickly they will recover. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Charlie.

    Thank you for submitting your question regarding Halpert. He will need to see his veterinarian today. Being such a young puppy, it will be very easy for him to become dehydrated. He is losing fluid in both the vomit and diarrhea. He will likely need fecal testing to ensure he does not have the parvovirus nor other intestinal infections. He will likely need fluids to rehydrate him, medication to control his nausea and vomiting and something to treat any infection that is diagnosed. In the meantime, try to offer small amounts of food and water to see if he will take it. I hope this information helps!
