Work Hard, Play Hard

James Aguero


My name is James, but I also go by Fuzzles! I've worked with dogs and their humans full time in downtown Denver and the surrounding areas since 2017, first by dog walking and boarding, then beginning to train formally in 2020.  


I grew up with dogs in the suburbs of Houston and understand that living with a dog downtown is very different by comparison, whether that's the size of available indoor space, amount of activity as soon as you're outside, or frequency of loud noises at all hours.


My goal is to help dogs and humans thrive in their shared space and lifestyle, ensuring everybody get what they need from the relationship. I know a lot of us are busy and active, so I work with clients to make realistic and progressive steps to success!
