My mate has a nice little free certificate for her dogs to be designated as emotional support dogs. She printed it off some website.
She sincerely needs help with her PTSD, but these two are nervous wrecks themselves - one in particular attacks men (including biting my brother) if they walk past, both jump all over her and other humans all the time and she thinks it's cute. They are not emotional support animals, in fact I'd argue they make her more unwell with the stress they put on her all the time.
This is exactly the kind of dog that is not suitable to be described as a support animal or a disability aid. They are not trained to do anything, not even behave themselves.
