HDM-
For some reason, the “theory’ is out there that two litter mates will bond and be dependent on one another- more so than with the owner. I am not really sure what the “whole” thought process is behind this belief, as quite frankly, I have never seen it be an issue. If an owner is spending time with the pups, teaching them, playing with them, there is no reason for that to occur. I have had no more issues with actual litter mates, than with two the same age raised together who think they are litter mates, lol.
