The Happy K-9 Training and Rehabilitation/Nelson Mendoza I am a results oriented dog trainer and work any tools and techniques that get those results. About me:

Hello everyone!

This is the official fan page of The Happy k-9 Training & Rehabilitation.I have daily updates, photos and videos of my board and train and my 1 on 1 in home sessions. With so many families struggling with even the basics of dog obedience, this page is a breath of fresh air that shows the results and the training of real world dog training. So many families have gone to 6-12 even 18 weeks of dog tr

aining and still not even gotten the basics down. It is not supposed to be like that and I offer folks an alternative. My name is Nelson Mendoza and I am Obedience dog trainer, i train dog owners and rehabilitate/ educate dogs. I also deal with owners that struggle with dog and or human aggressive dogs. I would like to welcome anyone and everyone to my page. We will update pictures and videos weekly when dealing with clients and will update daily with FREE training tips and advice. Feel free to ask any questions you have on training, exercises, tools, bonding tips, anything that comes to mind. Welcome and looking forward to change owners and dogs lives! The way your dog is today does not have to be the way it is tomorrow.

The answer usually isn’t more training… it’s better habits 🐾✨

Every transformation starts with the small things most people overlook.

Dog can’t settle in public? Start at home.
Dog pulls on walks? Build engagement first.
Dog ignores commands? Make expectations clear.
Dog struggles around distractions? Don’t skip the foundation.

Stop looking for shortcuts and start focusing on what you can improve today.

The results you’re looking for are built one rep at a time.

A little recap of what we’ve been building lately 🐾

From training sessions to go-homes, every dog shown here represents progress, structure, and a stronger relationship between dog and owner.

Real dogs. Real training. Real results.

We’re officially booking for June/July and spots are starting to fill up fast. If you’ve been thinking about getting your dog trained, now’s the time to lock in your spot.

Different ages, same goal 🐾🖤

Gunna at 7 years old and Violet at just 5 months showed that no matter where a dog is in life, there’s always room to build better communication, confidence, and structure.

Watching these two learn side by side was the perfect reminder that training isn’t about perfection — it’s about creating clarity, building trust, and helping each dog become the best version of themselves.

The before and after speaks for itself 👏
More focus, better obedience, and a stronger connection all around.

So proud of the progress these two made together.

Drive without direction turns into chaos… but Cali found both 🐕💥

High-drive dogs don’t need to be “calmed down” — they need clarity, structure, and an outlet that makes sense to them.

Cali came in with intensity and left with focus, control, and purpose.
Now that drive works for her, not against her.

That’s the difference when training is done right.

Boston, this is the standard.

Introducing- 1-year-old Hades, newley adopted came out the shelter with a lot of frustration and unfamiliar to the real world. Being returned 3 times before the age of 1 made it clear he needed a full reset due to never being taught how to deal with the real world and all the stress it brings. He had to be just as involved in his own success to be able to come out truly feeling different when encountering stress in the real world. I.e dogs, people, kids, bikes, traffic, etc. We appreciate for making the trip all the way from Colorado and trusting us with this love bug for 6 weeks! Full transformation video coming!
