HOUSTON -

A Houston man is accused of tricking a good number of unsuspecting pet owners and performed an array of bogus treatments.

Authorities say there are 50 known victims and believe there are additional victims out there who don't know they were duped.

Twenty-six-year-old Wilfredo Gutierrez has already pleaded guilty to practicing medicine without a license. Police think he spayed at least one cat, gave bogus vaccines to dozens of animals and incorrectly treated a dog's broken leg.

Houston police say an animal cruelty investigation discovered Gutierrez was possibly practicing veterinary medicine without a license. Investigators say Gutierrez was using business names such as DogSmart Veterinary Services, Wilfredo Gutierrez Pet Services and Mobile Vet Vaccinations. He advertised using the phone number 832-748-2437 and provided veterinary services in pet owners' homes.

Gutierrez, who police say does not have a license to practice veterinary medicine, was arrested July 16 without incident. According to investigators, patient treatment cards were found in his possession and they believe he provided services for pets of unsuspecting citizens.  

Police say they are looking for potential victims whose pets were treated by Gutierrez. Victims are urged to call the HPD Major Offenders Division Animal Cruelty Unit at 713-308-3100.
