Dog Whisperer Cesar Millan Cleared in Animal Cruelty Investigation

Dog Whisperer star Cesar Millan has been cleared in an animal cruelty investigation, his attorney and the Los Angeles County District Attorney’s office said Monday.

The celebrity dog trainer had been under investigation after a February episode on his show, Cesar 911, showed a dog attacking a pig during a training session. The clip had angered animal rights activists and sparked an online petition calling for the show to be canceled.

Millan’s attorney, Brian Klein, said no charges will be filed after an investigation by Los Angeles County Animal Control found Millan and his team did nothing wrong, CBS News reports. Los Angeles County District Attorney’s Office spokeswoman Jane Robinson confirmed to TIME on Monday that the investigation was over.

Millan announced the results of the probe on Twitter and on his blog, saying he was “pleased but not surprised by this news.” “My team and I are 100% dedicated to the proper care of all animals and our animal handling procedures are safe and humane,” he wrote. “We will continue to rescue and rehabilitate even the most difficult problem dogs. Our work has saved the lives of thousands of animals that otherwise would have been euthanized.”
