My boyfriend's parents have a 1 month old Miniature poodle named Kenji, today he started vomiting for the past two hours, a light brown, watery substance with remnant of his food. At the moment they are feeding him pedigree from the can and they dillute it with water (which I beleive Kenji is way too young be eating this). Besides calling a vet is there anything else that can be done, to help Kenji or even suggestions as to what to feed a 1 month old pup?
