Nope. I don't believe in them unless it is somehow for the dog's protection.
The group I adopted Treasure from suggested I crate her for her own safety. I did it once and never again. She was never fostered. She was a brood mama for several years and then went to the adoption group. I'm assuming she wasn't crated at the farm but was crated at the adoption group.
Phoenix was never crated. He was fostered and didn't have any behavioural issues at all.
Loca was a wild women. She was also a brood mama before I adopted her, so I assume she wasn't crated at the farm. She wasn't fostered. I tried crating her a few times because she was very unpredictable, but she chewed on the crate. I stopped crating her after a couple of times.
I would never crate Iker the Galgo. I think it would be disastrous.
I once fostered a greyhound for a local adoption group. They paid me an unscheduled visit and the dog wasn't crated because I was home. Apparently I was breaking the rules, and because of that they wouldn't let me adopt him when he was bounced. I never understood their reasoning for crating when I was home, and never forgave the group or anybody associated with it for not letting me adopt him.
