Well, Britt. Here's the deal, crating (or kennelling) is MUCH kinder for Zeus than tying him up.
A crate is like a den. Once a dog gets accustomed to it, it becomes HIS cozy little home. His toys are in there, his blankie, and he's safe and hidden. Tying, however, can drive a dog bonkers. Plus, he's at the mercy of whatever happens by. Kids throwing rocks, other dogs, coyotes, etc.
Don't tie Zeus up. Get him a sturdy, solid crate ands start putting him in it for a few minutes at a time while you are there. DO NOT TAKE HIM OUT IF HE IS CRYING. That will just teach him that crying gets what he wants. You can take him out the MOMENT he stops, but NEVER while he's actually crying.
Start by leaving it open with some yummy treats and toys in there. Let him explore at his own liesure. Once he's routinely going in for a minute or so on his own, then close the door. Just for a second. Then let him out. You see where this is going. Once you're up to being able to keep him in there, always stash a few yummy treats under his blankie where he'll be surprised to find them later. Also, put in a Kong filled with peanut butter. That will keep him occupied.
He may have never chewed or destroyed anything before, but he's getting into his teenager stage where he is going to be a snot. Its an EXCELLENT time to get him used to the crate. It will keep him safe, keep your stuff safe, and ensure that he's a good boy and doesn't ever have to find a new home.
I can't remember, is he neutered? If not, this might be a good time to do that, too!
I hope this helps!
