More trust. Start here: mosaick9.com Mosaic K9’s mission is simple: strengthen the bond between dogs and humans, one day at a time, so dogs and owners can live happy, confident, purposeful lives together. Owned and operated by DJ Busch, Mosaic K9 provides in-person training, virtual coaching, and a monthly membership program for dog owners across North Dallas, Texas. Mosaic K9’s philosophy is balanced, relationship-based dog training built on fair expectations, clear communication, and mutual understanding, so you and your dog can build real skills, real trust, and reliable results that carry into everyday life. I specialize in:

-Aggression & Reactivity
-E-Collar Training (done right) and Off-Leash Reliability
-Basic Obedience and Manners
-Puppy Training
-Leash Skills

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.

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.

Welcome to board & train, Indy! Indy is a 7 month old German Shepherd. A very sweet dog who carries the crazy puppy energy to an extreme. While she’s here we’ll be working on a lot of obedience and impulse control, and of course playing a lot of tug with rules.

Got to enjoy some time with my best friend at the beach last week. Grateful for the time to get away!

Just because a dog will listen when you’re standing right in front of them with treats doesn’t mean they’ll listen when the picture changes.

Where you are, what you’re doing, and what’s happening around them all matter.

Practicing things like this is what teaches the dog to listen in different scenarios and builds real reliability.

Sadie wouldn’t even lay down for me a week ago, so I’ll admit even I was a little surprised when she stayed as the leaf blower came out.

The distraction wasn’t planned, but I figured I’d let it ride and see what she did.

She passed with flying colors.

This is exactly why I like teaching behaviors with limited distractions first. Make the expectations clear. Give the dog a chance to actually understand what you want. Then, when distractions show up later, they have something solid to fall back on.

Great job, Sadie!

People are always intrigued because Beau is constantly staring at me.

Engagement at this level is a learned behavior — it’s not natural. Yes, I truly believe Beau loves me a lot, but not so much that he would naturally stare at me all day long.

He does this because he’s working.

He’s an energetic, young dog who is always looking for the next thing to do. Without direction, that energy could easily turn into chewed-up couches, baseboards, kids’ toys, and so much more.

A lot of what people call a behavioral problem isn’t really a behavioral problem at all. It’s a dog that has no idea what it’s supposed to be doing. It doesn’t understand where its purpose lies because nobody has taught it.

That’s not the dog’s fault. That’s the human’s fault.

Yet people are incredibly quick to blame their dogs for problems they helped create by failing to give the dog enough structure, direction, and leadership.

Engagement like this has been built over years. Beau loves to work, and he’s always willing to look to me for the next task, game, or direction.

If your dog is constantly creating chaos in your house, you might need to spend a little less time looking at the dog and a little more time looking at yourself.

Meet Sadie.

Sadie came to Mosaic K9 about a week ago for Board & Train. Overall, she’s a great dog — always happy and ready to do something, especially if it involves being outside.

She has also shown some possessive behavior, especially around the space surrounding her favorite people. That has included barking, lunging, and nipping at guests in the past. The most recent incident involved jumping over her owner on the couch to nip at their girlfriend’s child.

While she’s here, we’ll be building a strong obedience foundation, testing that obedience around distractions, building impulse control, and putting her in situations where she has to learn how to listen even when there’s a lot going on around her.

The goal is pretty simple: send her home safer, more reliable, and better prepared to handle the situations that have caused problems in the past.

She’s already done a tremendous job during her first week. The barking and lunging toward the other dogs in the house and my daughter has already stopped.

Much more to come with Sadie!

Recall is one of the most important things you can teach your dog. Teach it with a leash first, and you’ll dramatically reduce the chances of having to say it more than once.
