(FOX NEWS) - Cesar Millan, the self-taught dog behaviorist known to millions as the "Dog Whisperer," is under investigation for alleged animal cruelty, multiple media outlets reported late Thursday.
A spokesman for the Los Angeles County of Animal Care and Control told The Wrap that officers had visited Millan's training facility in Santa Clarita, Calif., Thursday. It was not clear whether Millan had been interviewed about the allegation, but KNBC reported that Millan was out of town on a business trip.
The station also reported that officials issued a 24-hour notice, requiring Millan to make contact with investigators.
The investigation reportedly stems from a recent episode of Millan's show "Cesar 911," in which a live pig was used in a behavioral training session with a dog who had recently attacked two other pet pigs. The dog bit the pig's ear, drawing blood, before it could be subdued.
Los Angeles County Animal Control Deputy Director Danny Unbario told The Wrap that it had received a single complaint about the incident and described the case as "active."
