I will try the second tactic of closing his snout with my fingers. Thank you! He is 8 months old and I can see he is definitely in some teenage faze. He gets daily exercise along with plenty of toys and play time with me, my Dad or his Daddy. He is stimulated from the moment he wakes up to when we go to bed, aside from when he takes little puppy naps and when he plays with his own toys on his own. He also doesn't handle being kenneled when we leave the house or when he is alone. He howls and cries non stop until we come home. Sometimes being gone for 3 to 4 hours at a time. We are receiving complaints from other neighbors. I am not sure what to do about this problem. It's been here since we brought him home. I am thinking a muzzle, but need to do research on that.

If the crate is inside trying turning the lights off or if they are off turn them on. Sounds silly but that's what it took to get Bella to accept crating if I was home and needed her in there for some reason.

Usually a muzzle won't keep a dog from making noise, and if you left it on him for very long he'd probably figure out how to rip it off. (Mine did, and that was with supervision.)

Try feeding him his meals in the crate, and if he has chew toys save them and only give them to him when you leave so that he has something to do.
