I have never used a puppy formula before, but I have to supplement my puppies for the mama runs out of milk and doesn't replace it fast enough so I started to use Esbalac. Since then puppies seem to have VERY hard stools, and sometimes can't go. I know I can add Corn syrup to formula, but how much?? I don't want them to go the other direction, where they can't stop going. :lol: Does anyone know how much to use to a 12 1/2 oz can?
