Hey Mac
Interesting site
The issue is that a dog must be trained to help you in some way and you must have a disability. There does not seem to be any real certification so it is wide open to abuse. You can register your dog with one of these private firms, you can get id cards, but there is no goverment entity to my knowledge performing any sort of certification.
This can result in legitimate service dogs not being allowed into places since it is open to abuse.
To give you an example, the above place would sell you the kit, will let you register a moral support dog, but ..... as of my last reading, moral support dogs are not covered under the ADA.
Lack of clear goverment standards create opportunities for abuse and restaurant owners, hotels and others may not allow the dog because they can not tell the difference.
I am not saying service dogs are bogus, but some are. Not everyone follows the few rules that do exist.
Other than payment, I went thru the entire registration process and forms, it never asked me for anything related to disability or training of the dog. Had I payed, my 5 pound Toy Yorkshire would have been registered as a service dog with picture ID card, certificate of registration, working coat, etc. letter for housing and airlines from a doctor would simply be a few hundred dollars to get anything I wanted in there. Only needed for housing and airlines, other places not required.
