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 bala

nced, 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.

An engaged dog is the foundation all training is built on. If you don’t have a dog that’s checked in to you, you don’t have a chance. Peaches and her owners have done a tremendous job! Pretty solid work for a 6-month-old puppy!

Pepsi’s board & train is finished. Now the handoff work begins. All of my board & train clients get unlimited access to me for the lifetime of their dog. Just because Pepsi did great at my house doesn’t mean she will at home. Our success now depends on my ability to teach her owners how to reinforce what I taught her, and their ability to implement it.

Pepsi has come so far in a little over a month. From jumping on my table the first day to staying down off-leash. Great job, Pepsi!

Before anyone says it… she’s never had an e-collar on.

E-collars are awesome, but they don’t replace teaching the basics.

That’s where a lot of people make a big mistake, including trainers.

Good job, Lady!

People often see the accomplishment, but not the behind the scenes work. Beau knows “place” well, but as you can see here, he struggled once the ball came out. This is the level of impulse control I strive for with all my dogs, and it takes practice. There are no shortcuts.

The amount of loose dogs I see in Texas is stunning. If people would practice simple things like this, Nextdoor would be much quieter.

Five dogs out together doesn’t have to mean chaos.

They can play, be excited, and still listen when asked.

That’s the whole point.

Control doesn’t ruin the fun. It makes the fun better.

It’s easy to stay when I’m standing right there.

Walking around the corner in Home Depot is a different story.

This is the kind of work that makes a stay actually mean something.

Pepsi spent most of her first week at the very end of a 26-foot leash.

We’ve done almost no actual leash training, but we’ve done a ton of recall work and focused heavily on building engagement.

Now when I stop, she immediately notices and comes right back to me.

It’s crazy how much the leash stuff improves when the dog is actually tuned in to you.
