Yes, I am glad I got those photos.
A couple of the crated dogs were barking, so they didn't seem perfectly happy. Yes, you're right that many dogs do like their crates.
You're misunderstanding our dogsitting gig (as we did too, prior to enlisting). We sat with CRATED/penned dogs. We didn't really get to interact with any of them! Very few people even used our services.
In the future, I'd much rather go to the show with people I know and hang out with their dogs in their rooms while they go to the special dinners ...
How odd! What was the point of that, do you know? What were you supposed to be doing for them? I can safely leave my dogs crated in my hotel room when I travel, for long enough to go to dinner or whatever. At the specialty, other than meals, the rest of tge time you can usually have you dog with you if you want.
And yes, we spent a fair amout of time in informal groups of friends and their dogs who got along well having “dog parties” in various rooms. One year we had a great time doing group recalls with trustworthy dogs on a big lawn behind the hotel. The next year, unfortunately coyotes had been seen near the hotel, so we didn’t dare do that. So instead, we found a floor where ALL the rooms were Havanese people. We had about 20 Havanese loose in the hall, calling the whole herd back and forth about a doven times. Their tongues were hanging out of their mouths by the time they got done, and more dogs got added as we went on, but BOY did they have fun!!! (As did all the humans! LOL!)
And yes, of course you are right, there will always be people who crate their dogs inappropriately, just as there will be those who don’t pick up their poop, etc. But you would HOPE that people would teach their dogs to enjoy their crates before leaving them in them!
