Training is tailored to each dog’s age, breed, and behavioral needs, with ongoing support provided between sessions. Puppy training emphasizes early socialization and good habits, while adult and senior dogs receive behavior-specific interventions.

Testimonials
So, so grateful for what Whitney has done for our family! We had a very leash reactive, anxious ‘Covid puppy’ that made daily walks and anything further quite difficult. Since working with Whitney, Ace has transformed into a whole new dog. We are now able to take him hiking, camping, climbing with us and are able to have complete trust in him off leash. Throughout our sessions we noticed Ace becoming more confident in general, and it has been so fun to watch Ace grow into his full potential. Now we are beginning to do the same training for our 9 year old dog. Very grateful for 303k9!

Whitney was amazing! We started working with him when Porter was 6 months old and within 5 weeks, he was walking around the park without a leash and his recall was perfect. Thank you so much for helping train Porter! Money very well sent. I highly recommend using Whitney to train your dog!
– Rileigh Ladyga
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.

About the Trainer
303K9 is a Denver-based dog training business led by Whitney Zink, offering personalized, hands-on obedience and behavior modification training for dogs of all ages. Whitney specializes in custom training programs tailored to each dog’s personality and the owner’s goals, with a focus on building trust, confidence, and reliable off-leash control. Clients report dramatic improvements in leash reactivity, recall, and overall behavior, with many able to hike, camp, and visit dog parks safely. Training methods include positive reinforcement, prong collars, and remote (e-)collars used as communication tools—not punishment. Whitney also provides puppy foundation training, behavior modification for stubborn or anxious dogs, and teaches owners how to maintain progress after sessions end. The business serves dog owners throughout the Denver, Littleton, and Parker metro areas.
In addition to private training, 303K9 offers structured 5-session packages designed to deliver measurable results, with a minimum commitment required for off-leash training. Whitney’s personal experience with a formerly aggressive dog inspired him to create a more effective, compassionate training approach. He is an AKC Canine Good Citizen evaluator and has trained therapy dogs for hospitals and Denver International Airport’s Canine Airport Therapy Squad (C.A.T.S.), demonstrating real-world success with trained dogs in high-distraction environments.
Accomplishments
