my gf's parents recieved a Norfolk Terrier, and only he is like 2 or 3wks old, and their to subborn to take him back to his mother. Well I want to know what should they be doing for him(no name yet)? and he seems a little constipated, I mean he pees, and poops very little. They are giving him Esbilac puppy formula(powder), and massaging his tummy. I did notice that when he was pooping that he was whinny a bit, is that normal? What else should they be doing for him.
