<human>: Long story short, I know Littermate Syndrome exists and as such, it prevented my sister and I from adopting 2 puppies out of an Alaskan Malamute/Australian Shepherd litter. We initially had our eyes on a multicolored female, and a mostly tan male. However, we settled on the female and left. Two weeks later, my boss went and picked out that same male I had my eyes on. He told me that while he really would like to have faith in his kids' promises to do well by the dog and fulfill their responsibilities that come with it, he was wondering if I might consider taking the male if, after 1 year, his kids failed their responsibilities. My question is, since the male and female (from the same litter) were raised separately and in different homes/with different people, will Littermate Syndrome still be something we have to worry about? Or could we rehome the male in with our female (they will BOTH be neutered and spayed at the appropriate age)?

Can you condense the text into a few key points?
<bot>: In 1 year, if my boss decides to give his male puppy to me (who owns the male's litter mate), do we still have to worry about Littermate Syndrome wreaking havoc in our household?
