Looking for advice on how to help puppy become comfortable being left on his own. He is still only 10 weeks and we have no plans of leaving him alone yet, but figured we should start the training. At the moment he spends most of his time with us in the living room free under close supervision or in his puppy pen. If we leave him in the pen even just to go make dinner, he whines and cries. Usually he will eventually settle, but clearly he wants to be where the action is. I was hoping staying in the house but nonchalantly moving between rooms would be a good way to gradually get him used to us coming and going, but maybe I'm asking too much too soon? How have you all taught your dogs to be happy left alone? We are hoping to build up to being able to leave him for 8 hours in an indoor / outdoor dog run once he is older although most days he will be with either me or my husband all day. Advice much appreciated!
