Pro Dog Trainer

I’m AndrewPena owner/trainer I’ve been training dogs full-time since 2018 but it has been a hobby since 2010. I grew up loving dogs, everytime I would go hang out at my friends houses I would love to play with their dogs. Unfortunately I was never able to have my own because my mom was allergic to cats and dogs.

When I turned 21 and moved out on my own, the first thing I did was get a German Shepherd off of craigslist. Not the smartest thing to do but I didn’t really know much about good breedings etc. I quickly learned that he needed some sort of training so I found a trainer and started Henriks training journey! little did I know I was also starting a journey of my own.

Later down the line, my trainer saw my passion and offered me a job, so I took it and knew this is what I wanted to do for a living, the rest is history!


We focus on owner training as much as dog training!

At High Caliber Working Dog Training, we understand that living with an aggressive dog can be stressful and overwhelming. That's why we offer ongoing support and guidance throughout the training process, so you never feel alone or unsure of what to do.
