Lawmakers are calling for changes to regulations of dog trainers after a video showed disturbing treatment of a dog by a trainer in Oceanside.

A bill being proposed by state lawmakers would require state licensing for all dog trainers and the completion of a training course. It would also allow the SPCA to enforce the regulations and ban convicted animal abusers from being licensed.

"I was shocked to find that we are totally in an unregulated field where there is no licensing for dog obedience trainers. There's no one checking the qualifications of such individuals," says state Sen. Todd Kaminsky (D-Rockville Centre).

As News 12 has reported, the video appeared to show Brian DiMartino, of NYDogWorks, repeatedly jabbing a caged pit bull with a large stick.

Oceanside resident Tommy Marrone says his dog suffered the same treatment.

"I brought my dog to this animal trainer and he turned out to be a monster and I regret it every day," he says. His German shepherd, Zeus, was 5 months old when he took him to NYDogWorks. When he got his pup back, Marrone says some of Zeus' teeth were missing.

"It wasn't later until I found that when Brian went to poke him with a pole, my dog opened his mouth and the pole went down my dog's throat," Marrone says. "That's what knocked his teeth out."

Marrone says a witness also told him that Zeus was punched, kicked and choked while in DiMartino's care. He says that witness sent him the video of DiMartino jabbing another dog.

That video led to an investigation by the SPCA, which says there were 13 dogs in DiMartino's care when the investigation was opened. DiMartino has not been charged at this time and has denied allegations of abuse.

The SPCA says it is still investigating NYDogWorks. The other dogs found there were returned to their owners and checked by veterinarians.

The proposed animal training law will be introduced during the next state legislative session in January.
