I'm sorry Milo isn't feeling well. In puppies that are vomiting, we need to rule out things like intestinal parasites, foreign bodies, infectious causes like parvo, or genetic conditions. I recommend you make an appointment with a vet to start with a stool sample check for parasites. After that they can come up with a plan to help your puppy feel better. Kisses to Milo!
