We couldn’t recommend Whitney at 303K9 enough! In just 5 sessions our corgi has completely transformed into an obedient, well rounded dog. Her personality never changed, she just actually listens now! She has more structure, knows what she needs to do, and meets our expectations immediately. Whitney teaches you how to use certain tools to use even when he’s not around, so the training lasts. We couldn’t be more satisfied with his training.

I cannot recommend Whitney enough for anyone in need of a top-tier dog trainer! When I first reached out to Whitney, I was at my wit's end with Dorito, my 10-year-old street rescue from Ecuador. She had a serious problem with interacting with other dogs and was incredibly stubborn—definitely what I thought to be an impossible case. I was skeptical that anything could help her in just five weeks, but wow, I was wrong. Whitney gave each session 100% attention and put in so much effort to understand Dorito's unique needs. He came prepared, always offering more than I expected and making every single lesson a positive experience for both Dorito and me. I actually looked forward to doing the "homework" because Whitney taught me so much about not just managing Dorito’s behavior, but understanding her on a deeper level. What really stood out, though, was how Whitney was always available to answer any questions or concerns I had between sessions. He was incredibly responsive and never made me feel like I was bothering him, even if I had multiple questions throughout the week. The results? After just five weeks of training, we brought Dorito to the dog park—something I had once thought was impossible—and she did AMAZING. The transformation in her confidence and behavior has been life-changing. Whitney truly is a dog whisperer, and I’m beyond grateful for the care, patience, and expertise he brought to our sessions. If you're looking for a dog trainer who gets results, builds a real connection with your dog, and is always there for support, Whitney is the one!

Before meeting Whitney, we had exhausted all efforts in training our 7 year old golden doodle. Just 5 weeks of training has completely changed our lives for the better. Whitney assisted us on walks and taught us all the techniques necessary for correcting unwanted behavior. We were able to take all of the lessons throughout the sessions and apply them to our other dog as well which also proved success. Our biggest fear with dog training was that we never wanted our dog’s personality to change and have them “broken”. With Whitney, we had the exact opposite experience. We are now able to see our pup’s true personalities while playing with others which in turn has made our lives better. We highly recommend Whitney’s training!

Whitney is an awesome trainer! I noticed a HUGE difference our dog. She was constantly pulling on walks and made me dread going out with her. By the end we confidently walked around Wash Park off leash with no issues! I can’t recommend him enough as a trainer. I tried Pavlov and unfortunately didn’t get much out of it. We will continue to work with Whitney and only Whitney going forward. Well worth the money!

Whitney was nothing short of sensational in his training of our pup Romeo. I met a well trained dog at a park by our house. Was very impressed and got Whitney’s info from the owner. Whitney was punctual, professional and had Romeo dialed into commands on day 1. Romeo is now obedient and follows commands off-leash and has developed our complete trust. It has made camping, hiking and social/dog interactions 100% anxiety free. I absolutely recommend Whitney’s services. You will not be disappointed!!
