It depends on the dog. We've used both the plastic kind and the metal kind. We had one dog literally chew through the plastic crate in a matter of hours on day while we were gone. So, we replaced it. This time, it took much longer, but he still got out. This time he left the plastic alone, but destroyed the metal door.

I kid you not! (Didn't do much for his teeth, I might add

). He literally ripped the metal frame door apart. I was so shocked I took the door to my vet and showed it to him. His response upon seeing the door was: "

Good Lord, Deb! Was somebody in the house?" (meaning a burglar) Then he went on to tell me of another one of his clients who owned a large breed dog who did the same thing to its crate and there WAS a burglar still in the house (hiding in a closet apparently - minus a few fingers and blood).
So, we figured next move would be to get a very sturdy metal crate. A big one, with thick metal bars. We ended up getting a very large one, to give him plenty of room (thought perhaps he was claustrophobic) and so he could see out. He got out of that one too,
by bending the bars of the door and then forcing his head out, which, in turn, allowed the rest of him out.

So, it depends on the dog in the end.
I would advise against wicker or fabric. WAY to easy to destroy. Plus, with the wicker, you can't clean it.
Right now we have a very large Deluxe Edition Petmate wire kennel/crate. The old fella who broke out of so many kennels so long ago has since gone to the Bridge, but we still have dogs (some of his children, grandchildren, and great-grandchildren). Still have dogs in the house (wouldn't have it any other way), and still need a crate. No one seems to be quite as claustrophobic as Old Man Brutt was, so the kennel is holding up great. It's quite study. It has a slide out solid floor, two doors (one on top, and one on the end), a mini-door for putting in food/water without having to open the big main door, and a dual locking door. Plus, because it was the "deluxe" edition, it came with a cover complete with "window covers" and "door covers" so that if need be, we can keep distractions to a minimum for whichever dog is in the crate by lowering the fabric coverings (two on each side, running along the top of the sides, one along the top of the back end, and one over the door). All of them can be secured either in the "up" or "down" position with Velcro. Very good crate/kennel.
