A Word from Erica

Why I Love My Job:

My career with dogs has always been exciting, allowing me the opportunity to not only train dogs and their people, but also to help train dog trainers!

On Studying in David’s Training Programs:

David is the kind of person who pushes you to learn more. In passing on his knowledge and skills he encouraged me to try things his way, while keeping my own style. I always enjoy discussing a case with David because he is always asking a question that keeps me thinking and searching for answers. His way of encouraging me has made me a stronger trainer, but also a stronger communicator, and listener. I appreciate all the skills that he taught and brought out in me. To this day when I teach leash walking in classes, I still use an expression and technique that I copied from the very first class I took with David.

A Word from Ferdie

On Running My Own Business:

I work for the City of New York as an ecologist on the Bronx River, but in the evenings and weekends I run my own dog training business. I have private lessons in my clients’ homes or in a nearby park to practice in the real world. I help clients with everything from raising a new puppy to modifying aggressive behaviors. My dog training business is expanding which is very exciting.

On Studying in David’s Training Programs:

My experience with David really helped me become more confident as a professional dog trainer. He taught me how to work with people and listen to their issues. He taught me how to think critically about the way I was coaching my clients and helping them achieve their goals. I learned that it is important to show clients how progress is best accomplished in small steps rather than pushing a dog too hard. In addition, David taught me many great exercises to teach clients that are a foundation of any basic manners/obedience training program.

I think David is a great communicator. His advice was always helpful and he is one of the most positive people I have ever worked with. I have a lot of respect for his professionalism and the passion that he has for his work.

A Word from Sarah

On Running My Own Business:

I started Side by Side Dog Training in 2006. I offer private in-home dog behavior consults to help resolve issues ranging from new puppy problems to fear and reactivity.

On Studying in David’s Training Programs:

David was a wonderful teacher who led by example and gave specific, helpful and challenging feedback. I learned valuable techniques for training a variety of behaviors. I also learned good teaching skills to pass along training techniques to owners. David was always a pleasure to work with: professional and personable at the same time.
