Dog Behavior, Dog Training & Dog Bite Expert

Jonathan Klein passed away peacefully on December 30, 2016 after battling a recurrence of lung cancer.  He was the founder of “I Said Sit!” School for Dogs and the dog training center in Los Angeles will continue to help people and their dogs. Please visit for more details.

My name is Jonathan Klein, and I have owned and trained dogs for over forty years. Dog training began as a childhood hobby, which evolved into a 25-year career as a professional dog trainer, dog behavior consultant and a dog bite expert witness in Los Angeles, California. My goal has always been to educate the public and promote safe and humane treatment of animals. After years of experience working with thousands of dogs and their owners, I have developed methods that are kind to the dogs, fun, and consistently provide excellent results. I have also had the honor and privilege to be recommended by my peers as a trainer and behaviorist and as a go to resource for information on dog behavior. I am certified as a dog trainer and as a dog behavior consultant.

I have been voted “Best Dog Trainer in Los Angeles” on MYFoxLA and CityVoter consistently since 2009. Many media agencies use me as a dog bite expert and as a source for quotes and content for their articles on various aspects of dog training and behavior. I am called on regularly to do behavior evaluations and provide expert testimony in problem and aggressive dog cases.

This site is filled with information including many of my articles on dog behavior and training including problem prevention and solutions. If you have a need for training or a legal or media request, call me directly. If you would like me to contact you, please click here to email me or fill out this call inquiry form and I will call you promptly. Again, thanks for stopping by – I look forward to helping you.

Jonathan P. Klein, CDBC, CPDT-KA
