Any thoughts on this: pups bonding with other dogs instead of owner, potential effects?

In the canine sports world we call it second dog syndrome. Where the puppy attaches to the dogs more than the handlers. It can happen alot more frequently if you dont work with your puppy everyday and spend alone time with it. Second dog syndrome is not fun. Alot of times they are very detached from their owners and dont even respond when called. Im not sure if it blocks their senses on being able to pick up on our body language because once again. It depends on how much time they've spent with humans to know how we work. I think if you were to seperate 2 dogs then the one dog with the second dog syndrome would be lonely and not adjust as well as a dog without it.
