A note about play in dog training:

Play, when it’s done correctly, is one of the most powerful tools we have. It helps us build a clear communication system, teach impulse control, and create engagement, trust, and reliability that holds up outside of training sessions. The best part is how dogs learn through it. We can train in a dog’s highest state of arousal, when self-control is hardest, so we are pressure-testing obedience while the dog is having the time of their life. That’s why structured play isn’t just fun. It’s a premium training tool that strengthens the relationship and makes skills stick in the real world.

The leash is one of the best communication tools you have. It speaks a language dogs understand.

Thresholds are powerful, and they keep your dog safe. Practicing things like this would dramatically change how many dogs get loose out here in Texas.

Obedience isn’t about obedience. It’s about the communication and relationship you build with your dog. It’s what affords them to live a fantastic life.

Basic obedience matters. Not for the sake of obedience, but for the relationship you have with your dog and the life it allows them to live. And it’s not that hard, assuming you know how to communicate with your dog in a way they understand.

Most dogs can do this, many never will. And it’s not their fault.

Indy is officially addicted to the game of tug. Pay attention to how quickly she turns around when I say "you ready?"

She's beginning to pull harder and is truly interested in beating me. There is still a ways to go, but I figured it was time to start adding some rules to the game a couple nights ago. Things like not biting the toy before I say "yes" and outing the it when asked. She's only going to start working harder to win the toy now. And I can continue building communication, impulse control, and rules into the game.

Great job, Indy!

Getting dogs to chase food in your hand is a great way to make training fun for them. By the time Indy is finished with training, she’ll love this game. Things like this also become invaluable when taking dogs into new and distracting environments. Just a little bit of chasing can change the entire outing.

This was the first time Indy and I played together, and it’s arguably the most important thing we’ll do together while she’s here. We’ll build all of our communication through the game. Once she’s addicted to playing, we’ll add rules that I’ll enforce. Communication, impulse control, and learning to think when highly aroused are just some of the benefits you get from playing tug. Not to mention the relationship it builds between you and the dog. She’s already gotten so much better at the game, and I’ll share that soon.

Letting your dog rush out of the crate is a big mistake. Especially when it’s the first choice they make in the morning. Things like this set the tone for the relationship you and your dog will have.

Enjoyed some time with Beau in Flagstaff on the way home from California. Training isn’t about obedience for me, it’s about the life my dog and I get to live together because of it. Love this dog and all we get to experience together!

Doing some basic recall practice with Indy while out on our walk.

I love Flexi leashes for this kind of work. They give the dog some freedom to explore, sniff around, and enjoy the walk while still allowing us to mix in a little obedience here and there. Once we start focusing on leash skills, we’ll ditch the Flexi. But by that point, she won’t be getting too far ahead of me anyways.

One thing I always do when teaching recall is back up quickly the moment the dog commits to coming toward me. Dogs naturally love to chase, so why not use that to our advantage? It helps build speed and enthusiasm into the recall.

And if there’s one behavior you want your dog to perform quickly, it’s recall.

A dog that casually makes its way back to you might be doing just fine in a quiet environment. But throw a squirrel, bunny, or something else exciting into the picture, and suddenly you might have some competition.

I want my dogs to come running when I call them, not just eventually make their way back.
