Cesar Millan found himself in the doghouse for having his pooches on a beach pier ... and now cops are using the celeb animal trainer as an example of what NOT to do when visiting the area.
The Redondo Beach PD took to Instagram to let followers know Cesar was recently given a warning for having his dogs on the pier. Lucky for all involved, cops say Cesar was quick to comply ... even snapping a smiley pic with officers, which they included in the post.
The caption continues with a warning for anyone else who might wanna take their pets for a stroll in the area, "We would like to take this opportunity to remind you that dogs are not allowed on the Redondo Beach Pier! Not even the dog whisperer."
Redondo Beach PD thanked Cesar for his understanding, and you gotta imagine, the post will likely lead to fewer people bringing their animals on the pier.
So the lesson ... no dogs on the pier, celeb animal trainer or not!!!
