Why do some dog trainers say that you should encourage your dog to make direct eye contact with you?

I remember in obedience training with my dogs, we did a watch command where we held a treat in front of our noses, and used the command watch. The dog became totally focused on the treat and had eye contact with us. There is a fantastic hub about this by Julie-Ann Amos.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
