>>I've got her in the crate inside. She can see most of the living room, and the crate is next to where our other dog usually sleeps while we're gone (he's a 14 y/o purebreed Siberian Husky, and not prone to mischief, as he's... well... OLD.)
>>
>>She -- the probelm dog, "Casey" -- was digging outdoors when we were gone. There's a doggie door from the kitchen to the backyard, so they can go outside to do their business. When my wife and I would leave, we'd leave the dogs free in the house, and she'd head to the backyard and dig up the plants, flowers, etc. I should mention that I live in Phoenix, and we've a "desertscape" yard (no grass, just sand, gravel, and cacti, among a few flowering plants.)
>>
>>When we put her in the crate, she tries to force the door open (or tries to spread the wires apart) by pushing her snout and nose through them. This results in cuts, scrapes, and swelling to her nose and snout. Part of me wants to say "Don't give in: she'll stop if it hurts too much, and she has to learn..." but part of me doesn't want to see my dog injured. Maybe I'm being a wimpy, soft-hearted weenie?
>>
>>My only other thought is to lock her up in the kitchen while we're gone and block the doggie door (lineolum floors.)

Some of this is her age and some probably breed genetics along with perhaps past experiences. For example, separation anxiety it made worse (even sometimes caused in the first place) by punishing a dog when you come home and find damage. I have an article about separation anxiety at the link below my signature. You'll find one on digging there, too, and one on destructive chewing.
I would suggest you look into a day care program--day boarding with your vet can work fine--for awhile. Possibly she could be stabilized on medication and accept the crate better. It takes several weeks. She should have her hips x-rayed in case pain there is a factor, and be spayed if that hasn't been done, since female dogs will often dig dens and nests for pups.
I think if you confine this dog to a room with the door closed, you'll get a few hundred--or more--dollars worth of further damage. If you can help her through this, probably by the age of two she will be okay loose in the house. I dunno about loose in the yard with expensive landscaping, though. A lot of instinctive behavior comes into play in the outdoors. I always supervise my dogs when they are outside. See my article on backyard hazards, too.
