"Free My Paws" is selling a service pet ID kit for $149 on SkyMall. The company also has a Facebook page.
One service dog owner in Colorado says it's becoming a rampant problem -- people trying to pass off their pets as service dogs.
"It makes it very difficult for those of us who use service animals and have a legitimate disability to have access to public places," said service dog handler Kyle Walpole.
The president of "Free My Paws" says he's providing a needed product for qualified animal handlers.
Right now, the law does not require registration or certification of animals to wear a service vest.
