There are LOTS of Certified Service Animals. The certificates are, literally, worth the paper they’re printed on. Anyone can print a Certificate and the animal is then a Certified Service Animal.
We run into the same issue with “Certified” Herbalists and “Certified” Massage Therapists and “Certified” Auto Mechanics. Certified just means someone gave you a piece of paper that says you took their training. It gives you exactly zero information about whether that “training” was a weekend workshop, a 3 year course of study or clicking on a web link.
Some schools/teachers in some areas of academics or trade will deal with this by having their course of study approved by the State Board of Education, or by being Accredited by a regional accreditation organization, or both. Being approved and accredited is an indication that at least an outside body has looked over your curriculum and said, “yeah, this is about the same as the other curricula we’ve seen and approved/accredited that bear the same name.” Being accredited means that your class/es are substantially similar to other classes Accredited by the same organization, and that your Credits for those classes should transfer to another school also accredited by that same agency. This is why if you’re looking at colleges or trade schools, you should look for an accredited program.
LICENSED is another matter, and really what people are talking about when they talk about “Certifying” “real” “legitimate” Service Animals. Licenses are issued by the State, and indicate that you (or the dog, in this case) have met minimum educational requirements, have certain duties the State believes you trained and therefore allowed to perform, and certain responsibilities you need to fulfill to keep your license current and in good standing.
Human example: I am a Certified Massage Therapist. I completed 1000 hours (18 months) of training at a State approved school. I got a Certificate from my school when I finished. My training is sufficient to allow me to apply for a License and get it. But because I have not applied, I am not and may not call myself or work as a *Licensed *Massage Therapist. I’ve spoken with others who have taken a weekend workshop in Massage and gotten a Certificate. They’re Certified Massage Therapists, too. They don’t have enough education to get a License, but they’re Certified.
So…yes. There are tons of Certified Service Animals. Some have been Certified by reputable, widely respected training agencies who know what they’re doing, weed out unsuitable dogs (and patients) and produce well-behaved therapeutic animals. Others are Certified by fly-by nights who don’t do a thing to ensure the well-being of the animals they certify, much less provide them with good training.
No State is currently Licensing service animals that I can find. I’ve found a couple of municipalities that are Registering service dogs, like San Francisco. They are not verifying the dog’s training or requiring continuing education, just reviewing the doctor’s letter of medical need and the patient’s affidavit that the dog is trained to assist. It’s about half a step up from what any shop owner can do - they do demand to see the actual paper from the doctor, but they cannot ask what the disability is or demand that you demonstrate the dog’s training.
