Actually, some states do have regulations regarding service animals. Mine does. I was quite surprised to learn that small horses can qualify as a service animal.
What I did have problems with however, was in learning how and where a person can train his/her animal for service, and what the qualifications are. I’d like to train my pup for low blood sugar detection, especially through the night when I’m asleep.
Prior to this, I had a dog who detected infections in other people, and who would posture to prevent me from contact with sick people. He did it on his own. My new pup goes nuts over my socks and I’m told that there is a certain scent given off by the feet when a person has a dangerous sugar drop, so she’s exhibiting signs of detection on her own.
I think there needs to be some sort of numbered registry system for service animals with the number and state seal clearly displayed on the animal’s jacket, along with a phone number an inquiring person could call to verify the validity of said service animal, or something along that line.
Also in my state, an animal is not considered a service animal if it’s need is for emotional calming. Federal laws may differ, and my state’s laws may be invalid since states aren’t supposed to over trump federal laws, but those laws do exist and can be researched on line.
I had a dog that could detect food on your plate.
