David Discusses His Background

He graduated from the very prestigious San Francisco SPCA Academy for Dog Trainers. This academy provides comprehensive and leading edge education to dog trainers, behavior counselors and other companion dog professionals. It is considered by many to be the "Harvard for dog trainers." The academy is run by Jean Donaldson, one of the foremost trainers in the industry and the author of many leading books, including "The Culture Clash", "Dogs are from Neptune", "Fight", "Mine", "Oh Behave! Dogs From Pavlov to Premack to Pinker", and "Train Like a Pro". "The Culture Clash" was named the number one training and behavior book by The Association of Pet Dog Trainers.

He is a strong believer in positive reinforcement methods.

He has trained various dogs of all breeds, size, ages, and issues ranging from extremely shy to highly aggressive. He uses a balanced approach that has proven very successful with dogs of all sizes and drives.

He loves helping people succeed and achieve all of their goals they have set for themselves and their dogs.

We had a great experience in David's Leash Reactivity class! I learned so many helpful skills, tips, and tricks to help me manage my dog's reactive behavior when she's outside on a leash. Her behavior has improved tremendously and walks have become so much easier! I can't recommend this class enough.

David was incredibly helpful! We learned so much and have seen dramatic changes in our pup’s behavior.

Thank you!

The staff at Tucker Pup's was very helpful with registering. David was very accommodating when we had to miss a class. He really watches how we are training, our motions, our speed, and gives very good feedback on how to improve. He makes the class very enjoyable and gives very easy step-by-step instructions.
