I also don't believe a emotional animal should be able to legally wear a service dog vest.
They can't legally. ESA animals do not have the same rights as service animals and cannot legally wear a "Service Dog" vest.
I love it when I see people with well behaved animals hanging out at restaurants or stores. I take my dogs into Home Depot and Lowes all the time now. I am a service dog trainer, so I regularly take a wide variety of dogs into restaurants and grocery stores. My vests must say "In Training", but no one has ever questioned it or had a problem with it, and I've never caused any problems, other than some people not seeming to like it, like you. We all have to tolerate each others idiosyncrasies. I tolerate smokers and people with horrid flatulence. I have to tolerate people with loud unruly dirty children. I think they can tolerate a quiet dog sitting still at my feet. Walk around Europe a bit and everyone takes their dogs everywhere. There is an etiquette to it, and ill behaved animals are not tolerated, but I like the trend here.The government here in CA won't let me carry a gun, but they don't seem to mind my malinois coming with me everywhere.
