When Coco was 10 weeks old, I sat in disbelief as I watched her jiggle the handle on her teeny little crate and let herself right out. We had a bungie chord around the crate for months. When she grew a bit bigger, we moved her to a medium size crate that my mother let us borrow. It was far more secure, so we didn't have any problems.
Recently, we bought her a SUPER SIZE crate. One like this:

And now I am wishing that I had splurged on something more secure like this one:

The wire crate seems a bit flimsy, but we bought it 50% off. So I thought we'd be able to use it for the rest of Coco's life. It's totally huge! But Coco is a smart cookie and has already managed to get out of it. Chris (my hubby) secured it with a bungie chord this morning, so we'll see what happens.
Honestly, we were expecting a "Keith Moon" type reception when we got home. Thankfully, she was sound asleep by the door - which shocks me. Coco has been on house arrest for one week due to her spay and she has been a BAD BAD little girl. Exercise is the key to obedience, and she's not getting any of that! I can't blame her. But the house was oddly in order. I thought at the very least there would be broken pens and ink all over the furniture, but she didn't do a single thing. Altho - I bet her puppy tummy is FULL of kitty poo, via the litter box. *barf*
Anyhoo...we'll see how this goes. If you have a smart German Shepherd or any large breed, I don't recommend these wire crates. Splurge for the more secure ones, as these crates are going to last the dogs entire life.
