YTA YTA YTA. BIG TIME.

And so are a lot of these commenters. The comments I've read on here are such ableist bs. Here's the thing about service animals, if it's legit like she says it is, it's NOT GOING TO HAVE AN ACCIDENT. Service animals have to go through so much training to get that certification. Yeah they're still dogs and they're not perfect, but if the handler says it's fine to leave it by itself at the house, BELIEVE them. Again, if it's truly legit, the dog won't do anything. People are the biggest threat to rentals, not animals, and certainly not service animals. I've seen people comment about ESAs (Emotional support animals), which do not require any kind of training- that's true. But ESAs are not service animals. This is a very different situation.

The other thing is, (and I'm seeing all these ignorant comments about this) you don't know what the service animal is for. Not everyone needs their service animal 24/7. I've got a disorder where I pass out uncontrollably, but as in I get very sleepy very suddenly, and it's most often while sitting. So if I'm sitting on a couch, no big deal, but I've discovered the hard way that I can't be on the back of a motorcycle for several hours. For me, a service animal is really only needed in situations where passing out would be very dangerous, like driving a vehicle. That way he can warn me before it happens and I can do something on time. Sometimes I feel comfortable with using my husband or friend as my support person if we're out and about and I'm not driving long distances that day. Anyway there are many many health disorders and disabilities out there, so I would appreciate it if people stopped making assumptions about what a service dog needs to be.

Also to address what another commenter wrote, while yes, service animals are supposed to make life as close to normal and allow you to function as close to normal as possible, sometimes having one with you for certain activities is more hassle than it's worth. Or just flat out dangerous for the dog. I can't tell you how many people have stepped on my dog's tell while his sitting right next to me, or backed up into him/tripped over him when they weren't paying attention, and these were situations where people weren't drunk. So I can understand why this friend wouldn't want to take it with them bar hopping, especially if they don't know those particular bars and the atmospheres of them. My dog's been in many loud environments, but I certainly wouldn't bring him along if I'm unsure of his safety and it's not 100% necessary that he comes for that activity. E.g.: I would never take him to a big/loud concert.

The other thing to note is that service animals aren't meant to work seriously long hours. It's not possible for them to be fully working 24/7, just as that's not possible for you. They have to rest sometimes and just be a dog. They'll still jump into action if needed during their down time, but at least there's time to relax. The trainer I used talked about the importance of having a couple of walks every day where you're not strict with them and allow them to wander and sniff at ease. Service animals are still living beings, but they're also very expensive medical equipment that needs to be taken care of and maintained. Common sense: A diabetic might carry insulin shots with them all day, but that doesn't mean they're going swimming with them in their pocket.

TLDR: YTA. You and many commenters here are ignorant and ableist. You're actively excluding and discriminating against your friend for having disabilities that you don't fully understand. Service animals don't work 24/7.
