Here's my 2 cents which I figure will prob not be popular. If I want to pay to take my 8 lb dog on a flight, pay the extra and stay in a pet friendly hotel and my dog is well behaved (doesn't bark and disturb others, house broke etc) and I clean up after it, then as long as it's legal and those places allow it, then why not? I def do NOT agree with ppl who fake service/emotional support animals. They ruin it for the ppl who legit need them. I get that dogs might make some people uncomfortable, but if my dog is curled up on my lap, in a carrier or whatever, if you are that uncomfortable around a dog that you would freak out about that, you probably need some counseling. As long as what I am doing is not offensive (racist, cussing etc) then it's not my job to make everyone comfortable. And again, I know that won't be popular either. I'm not saying that it's ok to be rude or be a jerk, please don't think that. But it's also not ok for your sensibilities to infringe upon everyone else.
For what it's worth, I've never traveled with any of my dogs bc they are a pain in my butt lol. My small one would bark at everything and my pit bull, while she's the goodest girl in the whole wide world, I don't want to deal with peoples dirty looks bc "OMG its a Pitbull!!"
