We just got a new boxer puppy named Briggs. He's 8 weeks old, and we are trying to crate train. He crys and barks uncontrolably. We are not sure how long to just let him "cry it out". I don't want to harm him, but I know he needs to learn its ok to be in the crate. We both work, but I do come home during lunch everyday. Today he's in the kitchen with a baby gate blocking the door. The neighbor girl went over to check on him for me and said he was still barking and crying loudly. What can we do. We did not have any trouble with our last boxer, but Briggs is turning out to be quite differant.
