[QUOTE]if there is a common practice we ought to do when bringing a new pup home/[QUOTE]
Of course, there is. As older your dog - that harder the issue falls on him. It s known, that some untrained dogs had stopped eating and died because their owners couldn't return from holidays quickly.
But, there are well known practices for all puppies of any breed. Normally people take holidays from work to spend the first month together with their new puppy. You should replace his mother, prove to him that you are a good foster parent and train him certain behaviour inside his new home. It should start early as crating your little one. The she-wolf leaves her cubs alone in the den for many hours, when she goes hunting, where they sit absolutely quietly. Train your puppy to stay in a crate when you go shopping, and to spend the night there for the start. When he's three months old leave him in a Daycare Centre For Puppies during the day, he wouldn't miss company of his brothers and sisters so much, and it is also good for early socialization. Leave him in kennels for a week when he's 10 months, leave him in kennels for two weeks when he's one year old - and so in progression, slowly. Carers, kennels' assistants, all these people will play a positive role in your puppy's upbringing. But, never ever entrust your dog to any trainers, nobody should train him, but you.
