I am not a Beagle owner yet but it bothers me to see no one answer your questions so I'll have a go. I raised Alaskan Husky's for years (26 dogs). All of my dogs were raised in litters and some litters I kept all of the dogs for their whole life. I never ran into any problems related to them being from the same litter, in fact the dogs who were closely related were better together. Huskies are pack animals. I Googled the syndrome and I can see were the dogs might be less social with a human if they are left alone together a lot. It is always important to remember My #2 of the top ten dog facts "Dogs do not think they are human!!! They think you are a dog". That means you have to assume your rightful role in the pack. That brings me to #1 dog fact "There is only one pack leader and it D*** well better be me". That is not an endorsement of abuse or cruelty. There is no excuse for that but it means you have to be the boss and you will gently but firmly demand the dogs attention and obedience. If you are the leader the dogs will naturally attend you and not withdraw from their human.
Incidentally most dog behavior problems stem from misunderstandings of these two rules.
For all of you true Beagle experts I apologize for butting in on your forum but since no one answered this question I thought I would chime in.
