WDWNT in typical fashion declares the dog policy is over just a few days ago, then flip flopped to say it's staying. Their mole needs to get it straight. Unless I missed it Disney has said nothing and the website still says it is a test until October.

I have no "dog" in the fight because I would never bring my dog and leave them locked up all day ........... but until Disney actually states their policy I'll wait.
I think bringing a dog to Disney World is a whole different story than taking your dog on vacation. I think the problem for many of us is that Disney has not stayed with industry policy and thrown all rules out the window. No breed or size restrictions and the dogs may be left 7 hours in the room alone. Given it's Disney World .......... and many folks stay gone that long and longer .......... I do think it would be selfish to leave a dog in the room that long. Disney doesn't require crates, that means these dogs are all over those rooms. Disney does say the dogs can't be on the furniture, well that is laughable. Disney says no dogs in public areas or restaurants, and it is being reported and recorded that dogs are in food courts, pool decks ... so no enforcement of the few rules they have.
I have two dogs, they are my family, I would never take them to Disney and leave them locked in a room for hours on end. Yes there are a few folks who say they will leave someone in the room with them during the day. And folks who do as you did. But I imagine both those cases are rare. I have a dog that had some awful experiences kenneling, so for a few years someone always stayed home with her and missed vacation unless it was to the beach and we all go, fur and all. She eventually came to love the doggie resort but I have a second dog now that likely would die of stress (he's on high stress if I leave even if he's with rest of family) ... so once again someone has to stay home with them.
I was at Disney last week, I stayed offsite, in a hotel built specifically for dogs.* It has rules. I wish Disney did but since it doesn't I won't go to those hotels.
*Home2Suites, built for dogs. Even the carpet was in squares so they could switch out one if needed. Well planned and set up for the furbabies.
I haven't seen anyone state that Disney ended it due to legal reasons. If they end it at this point it's likely due more to either too much work for the money coming in or guest complaints/cancelled reservations. But I firmly believe their lack of rules has set them up perfectly to be sued. They didn't follow industry standards so they have lined themselves in the cross hairs if something happens.
