About Denver Dog Guru


Denver Dog Guru's mission is simple: to help your dog live its happiest life while helping you bond in a way that is structured, loving, and balanced.


I consider myself a balanced dog trainer and human educator. My passion is teaching my clients dog psychology/behavior first, so you can understand the why behind your dog's behavior. Then I will show you how to rebuild your human-dog relationship.

Your dog is craving a calm, confident and consistent leader with clear communication and daily fulfillment. This is the recipe for realistic expectations and a loving, respectful relationship. Once your dog knows what to consistently expect from you, then you can have consistent expectations of your dog. 


Every day you are teaching your dog how to behave (good or bad), whether you know it or not. The question is, what are you teaching? Dogs are constantly talking to us in their own way; mostly through non-verbal cues and body language. I can help you identify these subtle energies so that you can better understand your dog.

Denver Dog Guru specializes in puppy training, behavior modification, on & off leash training and rehabbing aggressive, reactive and anxiety ridden dogs.


I will address your concerns with care and develop a training strategy that is digestible and structured for your family's needs.  


I am here to support you on this important journey. Every step of the way.


Meet the Trainer

Alex Nieto - Founder and Trainer


Growing up, I was passionate about two things: basketball and animals. I played college basketball and had no idea what I wanted to be when “I grew up.” Through the years, I realized that I connect to dogs in a way that not many people can. So, I decided to start Denver Dog Guru out of pure love for animals. I want to see dogs live happy and healthy lives while helping dog owners clearly communicate to build a fulfilling relationship with their canine companion. 

I live in Centennial, CO with my wife and we are expecting our first child this summer! In my spare time I enjoy playing basketball, eating tacos, hiking and spending time with friends and family.
