You would hope, but that is not always the case. Conrad can not, will not, ever be able to be home alone uncrated. It's not for my convenience, because it would in fact be much more convenient for me to not have to crate him. Crates are expensive and when people come to house-sit there are all these complicated instructions. I'd love to just be able to leave him and not have him have a panic attack. That would be great. That would mean I have a mentally sound dog, and nothing would make me happier than having a dog without a mental illness.
Believe me when I say that we tried everything before we tried crate-training with him, and nothing worked. Medication did not work (two different kinds tried), keeping him outside in a kennel run did not work (he injured himself repeatedly on the fence in his escape attempts), exercising him tremendous amounts did not work (at the time we lived on several beach-front acres--lack of exercise was never this dog's issue), extreme dog-proofing of the house only went so far because his main goal was to get out of the house and no floor, window or door was safe from his attempts.
For people who've never had to deal with a dog with such extreme issues that crating is necessary into adulthood, congratulations. We can't all be so lucky.
I know the haters will never believe me, but Conrad's crate is his touchstone. It's his security blanket. He needs it. When I come home after work and let him out, he's calm, relaxed, well rested, happy to see me, ready for our evening together. Before we crate-trained him, when I'd come home he would be in a panic, whining, crying, peeing on himself, exhausted (and I know it's taboo to mention issues of personal preference, but my house would also be a pile of rubble). I have to go to work and so does my husband, not doing so is not an option. The options for Conrad are live with us and be crated during the days, or rehome him with a shut-in who never ever ever leaves home.
