Sounds to me like you are doing a fab job!! It's usually extreamly hard to adapt an orphened puppy to a home life and if he's only whining for 20 mins you've done great!!! Puppy's who've not had the benefit of a mothers teaching are usually extreamly hard to train and badly socialised in manners but with the care and attention you are giving it sounds to me like you're going to have a calm settled dog very soon. Lovely to read such a positive and caring post. For such a horrific start to life this little one has been extreamly lucky.
