Some shots of our adorable clients enjoying Oregon’s seaside!

Posing with pumpkins, practicing their long- range sits, and admiring the coast while practicing “down.”

We LOVE seeing our clients working on their training even on holidays! It’s so good for pups to practice in different contexts, which helps them understand your expectations of them as their environment shifts.

There’s nothing these pups love more than an off-leash hike through the mountains! ⛰️🌲

Reminder that you should only walk your dog off-leash in designated trails and parks, and it’s important to have rock-solid recall before you do for the safety of your dog, other dogs and hikers, and wildlife.

We also always make sure the pups have their hi-vis vests on, so that they’re visible to hunters, other hikers and us!

Have you always dreamed of a dog you can trust off-leash? We can help you get the adventure dog of your dreams! The one that’s invited on every hike and camping trip. Get in touch!
