About Me

Meet Preston

I believe every dog and owner deserves a relationship built on trust, communication, and confidence. My goal is to make training clear, practical, and enjoyable for both ends of the leash.

LEASH TRAINING

Walking an obedient dog is a truly rewarding experience. The connection you share with your furry friend becomes evident as they walk calmly by your side, responding to your cues with ease. The joy of seeing them happily explore their surroundings, while maintaining focus and discipline, brings a sense of pride and satisfaction. It’s a delightful reminder of the bond you’ve built through training and trust.

HOME TRAINING

If you've hired dog trainers, watched online videos or read dog training books but your dog is still misbehaving, you need a more personalized approach. Your results should be immediate and your progress should be endless. Once I train you to be in control of your dog's improvements, you will see more of the behaviors you love and none of the ones you don't. This will ensure a happy, stress-free dog for life.

AGGRESSION TRAINING

When your dog sees others as threats or competition, they may react. I specialize in teaching dog owners to maintain stress-free dogs in order to ensure safety while still having fun. It's no fun when there's danger whether perceived or real. Once you understand your dog's unique personality and sensitivities, you will be able to avoid the stress that causes reactivity & aggression.  

FAST. EFFECTIVE. RESULTS.
