Really?! Since when have our society become so “weak” that they rely on animals to provide emotional support outside their homes? When did this become a ‘thing’? Stop this nonsense altogether. If you have anxieties, stay home, seek mental help and move on. We’ve stop smoking on planes because of second hand smoke and now we’ve allowed animals to travel next to passengers who may be allergic or have animal phobias, and don’t get me started on sanitation and/or behavioral issues. Just stop this nonsense, please. Short answer; don’t allow them, period!
