I have a wire, Midwest crate for at home use, and that is a BIG one. (much bigger than necessary, but we've never had a problem with him eliminating in his crate, so I like knowing he has the extra space) His is 30"L x 22"W x 24"H, with the two doors. (which I really like... makes it much more versatile) I really like Carol's idea of one that opens from the top, but I haven't seen one like that. I keep a table cloth draped over it for his privacy, and it is attached to an ex-pen, with a litter box and water bottle so he has lots of room and all the amenities when we are out of the house.
I also have two plastic crates, both from Petco.
I have this one:
though mine tan, not blue, and I thought I would really like it, because of all the ventilation holes. The problem is, with the rounded doorway, the door will not stay open on its own. The other problem is that the latches that keep the top attached to the bottom are not very strong. I would NEVER carry this crate with a dog in it... I'd be afraid it would fall apart. So this one is now his kennel in my office, with the door totally removed.
This is the one I use now for travel:
The door stays open or closed easily, and the screw closures that attach the bottom to the top are very secure.
I find that the plastic and wire crates serve different purposes. I really like the wire crate for his "permanent" bed room set-up. But it is too large for our travel trailer, and to heavy and unwieldy to take to shows. (I don't want to take the time to break down and set up a wire crate every time we go somewhere, even if I'd chosen a smaller one) The plastic one is very light weight, and it fits easily in our bedroom in the travel trailer.
So, if you don't travel much, you might get away just fine with just a wire crate. If you do a lot of travel or want to show your dog, a second, plastic crate might be a welcome investment.
In either case, I actually took Kodi to Petco with me, and let him try the various sizes to see what he was comfortable in, size-wise. With a puppy, of course, you will need to leave some "room to grow". If he is 10 lbs at 5 months, I think he's going to be a larger sized Hav like Kodi!
Timmy weighs about 10 pounds and I have been using one of my cat's crates for him and I'm wondering if it's getting too small (12"Wx20"Dx11"H). He sleeps in it at night and sometimes during the day if I bring it downstairs. I also put him inside when I'm going out, but between the four of us here he's never in it more than an hour or two during the day. It's one of those hard plastic ones, he can turn around and kind of stretch out, but definitely can't stand up in it. He doesn't mind it and does go in himself at night most of the time. Should I wait, or should I get a bigger crate now? I know I'll probably need one eventually since he's only 5 months old and will grow more. I would probably get (24"L X 18"W X 19"H) If I decide to get a bigger crate should I get another plastic one or a wire one? I liked this one and it's on sale http://www.petco.com/product/111704/...atesandkennels
Anyone have this one? If he likes having more privacy I know I can get a cover if I get the wire one, plus this one folds up which would be great for bringing back and forth from the beach.
