"Dog Whisperer" Cesar Millan won’t face animal cruelty charges, following an investigation by the Los Angeles County Animal Control.

A lawyer for Millan told FOX411 on Monday the investigation had concluded and no charges will be brought.

“We appreciate Animal Control’s comprehensive, independent, and fair investigation, which Cesar Millan actively cooperated with throughout. We were always confident that Animal Control would conclude that Cesar and his team did nothing wrong and that there would be no charges. We are very glad to learn that is the case,” attorney Brian Klein told us via email.

The animal cruelty investigation took place last month following on online complaint over footage from Millan's television show "Cesar 911," in which a French bulldog-terrier mix named Simon chases a farm pig and nips its ear, making it bleed.

Animal control officers and sheriff's deputies visited the TV star's ranch following the complaint.

Millan told FOX411 in a statement that he is happy to put the investigation behind him.

“I am pleased but not surprised by this news – our animal handling procedures are safe and humane,” he said. “Just like LA County Animal Control, my team and I are 100 percent dedicated to the proper care of all animals, including the farm pig in this case. I am continuing my work rescuing and rehabilitating even the most difficult problem dogs, which has saved the lives of thousands of animals that otherwise would have been euthanized.”

Millan, 46, is a self-taught dog trainer who became internationally known for his work on a previous show, the "Dog Whisperer," which won him an Emmy nomination.

“Cesar 911” airs on Nat Geo WILD.
