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!
