Whitney - you are amazing! I have watched what you did with a puppy who was so energetic that he did not know what to do with himself! You have converted him to be a happy contented dog who how has direction and happily listens to his dog mom. He is a pleasure to be around due to his good behavior. You were attentive during his training and listened to his mom's requests for specific guidance. You are a wizard! To anyone trying to find a trainer who is efficient, reasonably priced, and knows his field, Whitney is your guy!!

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!

Whitney was amazing! We were always told that our stubborn pup could never be trained or trusted off-leash, but in just 5 weeks, we’ve gone from struggling to get her to listen when it was time to come inside to trusting her to stay by our side and not run off on walks—even when completely off-leash! We couldn’t recommend Whitney enough!

Whitney was the best trainer ever!! He was beyond attentive, caring, and has all the information you’ll need! Colby Jack is a very energetic dog (Weimaraner and Cattle Dog mix) and with Whitney’s help he is now the best boy ever. CJ used to lunge at other dogs, wanted to play w everyone but now I can walk him around downtown off leash. We get compliments all the time about how well behaved he is!
Whitney will listen to your needs and provide exactly what you want in just 5 weeks.
Thank you, Whitney!

K9303 was the perfect fit for us! Whitney is attentive and extremely knowledgable in his field. He took the time to understand my dog's needs and quirks. Mabel is a changed dog. We are much more at ease and comfortable on walks as well as interacting with other dogs/people. Our bond and trust in one another has been strengthen because of Whitney's exceptional training program. Thank you!

I reached out to Whitney because my 2 year old german shepherd rescue Luna was very reactive with other dogs. I could barely take her outside without her jumping on, growling, barking and getting excited around any other dog she saw. It was hard because she loves being outside and loves going to the park so i knew i had to change that behavior so she could enjoy things that every other dog gets to enjoy.
Boarding and training programs that cost thousands of dollars were not in my budget, and i also wanted to find a trainer that would help to teach me how to train her and continue correcting negative behaviors that come up.
Whitney was amazing! We started with a prong collar and eventually advanced to an e-collar. I was unsure about these tools, but when you have a reactive dog, sometimes these are the only things they will respond to. The biggest thing for me was to be able to control luna when she sees another dog, squirrel or birds and of course to get her to walk without pulling. i really did not think it was possible and felt anxiety about how this would impact Luna in the long run. Whitney’s 5 week program was affordable and he has given me the tools needed to help train luna as she grows. He taught me about the relationship i should have with my dog: dogs aim to please you and once they respect you and know you are the one in charge, there is a mutual trust that keeps both parties safe, even in busy cities and stressful situations.

With practice every day, Luna now knows how to walk off leash (even though i’m still nervous about that part), she responds to my commands when she is reactive, and he temperament overall has improved. I cannot recommend Whitney enough!

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 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!!
