Oh @Quincy what a fun post!
I think there are perfectly good reasons for not allowing pets in rentals. Logical ones, I can 100% agree with. It's the other reasons that make me cringe. And to be honest anyone who says they just don't "like" animals kinda scares me. That's like saying you don't like Mr. Rogers or Betty White!
I've always allowed dogs and will continue to do so. Yes, there's a risk. But there's a risk with any guest and the guests that have caused me the most headaches and/or damage did not bring pets.
After reading the comments I imagine some in this discussion would be horrified to know I've traveled with all my dogs extensively because dogs LOVE and deserve to sniff the world around them as often as possible. This past October I took a week-long road trip with my current dog from NC to Key West. He had an absolute BLAST! He was oohed and ahhed at over at each hotel. He was a perfect gentleman at each restaurant and enjoyed special treats. (at one restaurant the servers kept requesting bacon from the kitchen to feed him, LOL!) We went kayaking and hiked many miles at some great outdoor spots and he took in all the sights and sounds with me. Leave him at home? He'd be happier? Ummm, no.
I only stayed at one Airbnb during this road trip, but I was appreciative that they allowed pets.
Griffin's world is much better with a variety of experiences. Whether a host wants to allow or not allow dogs in their rental is their call, but anyone who says dogs should stay home or be placed in a kennel because they're happier that way does not have an understanding of dogs' needs.
PS - Y'all do know that people do weird things and have sex (with or without a partner) in rentals, right? I'll take an accidental dog poop on the floor over unknown body fluids in the bedroom ANY day. Same for the aversion to dogs on the bed. Trust me, what my dog will do on your bed pales in comparison to the activities humans will do on your bed!
