What People Are Saying

See why people have fallen in love with Marlon and K9 University


I sent my 8 month old puppy to Marlon and she came back a different dog, in the best way possible. Marlon and I were in constant communication about my priorities for the training and he continuously sent me videos and updates while she was away. Upon her return, he spent a few hours reviewing everything with me and making sure I felt comfortable going forward. Ruby is now able to walk by my side without ever pulling, and she responds immediately to other commands such as off, sit and stay. I am so glad I sent her and look forward to using Marlon’s other services in the future!

Meet Marlon Leon:Dog Obedience Trainer,Penn Foster Career School
Hi, my name is Marlon Leon. And I've been around and working with dogs my whole life.Since the age of 18, I have been working in animal shelters and veterinary offices learning how to handle all types of dogs, even ones with aggressive and seemingly untrainable behavior.These are the dogs that made my heart sink. They made me realize who I was, and provided me with my lifelong purpose of helping them and their owners live happier, better lives.Loving dogs is easy, but communicating with them can be challenging, especially because they can't let you know if something hurts them or if they don't feel well.Understanding both aspects of a dog's behavior and a dog's health is truly the first step to my training process. Dogs want love and want to be loved. They form bonds with people based on their trust of people. The way that I train begins with me creating a bond, and letting the dog know - that I am NOT the enemy. Once you have formed this kind of bond with a dog, it creates a positive learning environment that will end in success.
