I love dogs, I've always had them. For me, it's not a vacation if I have to worry about my dog. He goes to 'puppy camp', I go to WDW. It's cheaper for him to go to puppy camp than to WDW!!!
BUT....there could be legitimate reasons that someone would want to have their dog with them. No, I don't think the 'I'm going to WDW for a week and I'm too sad to leave my furbaby at home,, so he's going with me' argument is a good one! Does anyone think that dogs are happy in a strange room, alone all day? Mine wouldn't be. But, there could be those that are traveling to another place, with a short stop at WDW, and they have their dog with them. Fine, I get that.
There have always been dogs at WDW. And now, with every Tom, Dick and Harry able to bring their dog with them, dogs will be in specific areas. If I am impacted by someone's dog (barking, pooping, snarling..whatever), yes, I will be speaking to a manager.
Now, a bigger issue for me??? Dogs in the parks. Yeah, I realize there are 'emotional support' animals. But in all reality, there aren't that many! People are getting away with saying 'Oh, I need my dog with me. She's my emotional support animal'. And that dog is about as much support as my kids are!!! These people have made it very difficult for those who truly need support animals!
