We cannot sing Happy K-9/Nelson Mendoza’s praises loud enough. This is THE premier dog training experience. Our family was so excited to rescue adorable Dudley Doodle from a fate of certain death in Alabama. Soon after greeting his transport van, though, we knew we were in deep trouble. Dudley turned out to be a COMPLETE menace, wreaking extreme havoc and destruction in our lives. He was very hyper, chewed imaginable and unimaginable things, and we were spending a small FORTUNE replacing the things he was destroying. None of us enjoyed walking him because he was constantly pulling and straining on the leash, barking at cars, trucks, buses, dogs, and everyone we met. Our dream doodle was turning our family life upside down. Enter Nelson and The Happy K-9 Training to the rescue! Nelson quickly taught us how to control Dudley rather than permitting Dudley to control us. Walking Dudley became a pleasure rather than an onerous chore. He is no longer a destructon, demolishing everything in sight. He knows his lace in the family scheme. Our home is no longer bedlam. We are a happy functional family thanks to Nelson’s training program. Cannot thank Nelson enough; he has our highest and most heartfelt recommendation.

Jackie and Family

We got Niño at 10 weeks and didn’t know he had parvovirus. He was dying, we took him to vets and there was no telling if he would make it and when he did, he got much more love than discipline, other than that he’s a great gentle loving dog. Taking him in the car is just crazy, he jumps everywhere and walking him was a nightmare. He walks you.. But after his first session with Nelson at The Happy k-9 training there was an amazing difference. Niño needs lots more time being trained but it was worth it, his walks are a lot easier, i have full control of him now and he enjoys his training. The old saying “you can’t teach an old dog a new trick” is not true! Anyone looking for a trainer that knows whats he’s doing, and wants to see real results, contact Nelson! Can’t thank you enough Nelson from The Happy k-9. Thank you, thank you, thank you!!

Karlee and My Family

My dog Sasha was crazy and didn’t listen at all! We couldn’t have people over or take her for a walk because she would freak out on everyone and any dog that would be passing by. When we got Sasha back from the Happy K-9 she was a happier, obedient and much more calmer. She listens to us now. We also are able to take her for a walk with no problem. With the training she got from the Happy K-9 she is a great obedient dog now. We are beyond happy with the results with our dog. This helped my family so much! We are so thankful for what Nelson from the Happy K-9 has done! THANK YOU!

Louise, Boo & Family

Nelson from the Happy K-9 worked with our 7 month old puppy Boo who had anxiety and was very energetic. Boo was not good on leash or good with commands. On Nelson’s first visit he had Boo walking nicely on the leash and was able to have him calm at home by using commands sit/stay.Nelson introduced us to the prong collar which I WAS nervous about using but it has worked WONDERS on Boo.He now is so much calmer at home and outside.The tools the Happy K-9 gave us to work with Boo have been wonderful and we continue to use them everyday. I highly recommend the Happy K-9 and would not hesitate in calling him again if I needed to.Thank you the Happy K-9 for all your help-:)

Jamie and Jim

Everything about the experience was worth it! Sophie has more freedom and play time than ever before, due to the training she now has. We had issues walking her before sending her to Nelson, but since being back, we’re able to exercise her off leash, and walking her is a stress free time for us too! Being away from her for some time was a small sacrifice to make for the benefits that we got from it! Absolutely recommend and trust Nelson and his team implicitly, fantastic experience throughout!

Julie and Louie

We got Louie as a 5 month old rescue pup.  He was a sweet dog but wouldn’t listen, was very high energy and hard to manage and integrate into our family with two young children.  After a few weeks of training with Nelson, Louie was a new dog!  He has the same energy and love but he’s dramatically more obedient, calm and a wonderful family dog.  Louie also goes to playgroup with the Happy K-9 five days a week and loves it, he runs to the door tail wagging every time the bell rings in hope that its time to go.  We are thrilled with Nelson and his team.  We couldn’t have asked for better training for Louie and for us and are grateful for the day to day care that he receives.
