I don't have a problem with emotional support animals per se.

I do have a problem with the lack of an adequate training system for allowing them where animals usually aren't supposed to go.

It's a non-issue with guide dogs, a guide dog without very rigorous training is worthless anyway. Many other service animals don't need major training to be useful, though, and thus lack the etiquette training the guide dogs get.

I don't care what you need the animal for, I just want it to get etiquette training similar to what the guide dogs get. Some sort of certification of this should exist (demonstration should be enough--in some cases the animals could be trained by their owner. Again, with guide dogs it's not an issue, the main guide dog training can't be done by someone who needs a guide dog so they're always professionally trained.)
