I crate Karma, mainly because she likes to toss the house around when she is free.. I didnt when she was younger so she can play and use the doggie door... but after sacrificing a few throw rugs and a wicker toy basket that was the last straw!!
Karma has been crated since she was young too, I would go home at lunch to let her out and play with her, try to tire her out, throwing the ball the length of the yard with three rows of jumps she would have to go over.
Now even though I hate to leave her so long, work requires me to be there for 10 hours!

But she does great, When I come home she will still run to me to greet me then run out to go potty.
I leave her with two of her favorite toys. I also leave her one cup of food and water. I got flat sided metal buckets. They hang on the side of the crate, and for the water one I use a clip (like whats on the end of a leash) to clip the handle to the crate. I just got the buckets and they working out great, she cant spill the water while its clipped.
I had a plastic cup that squeezed onto the crate before, but no matter what she would knock it down. And if I screwed the bolt to tight it would bend and break the plastic.
Also, maybe use a pillow or blanket that is easy to wash just in case there is an accident. But that is the wonderful world of girl dogs. They can HOLD IT forever
