What we are

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. I am a results oriented dog trainer and work any tools and techniques that get those results. So many families have gone to 6-12 even 18 weeks of dog training and still not even gotten the basics down. It is not supposed to be like that and I offer folks an alternative. For more of an insight of who are and to get a better feel for how we run things please visit our facebook page.

My name is Nelson Mendoza and I am a Dog Obedience and Behavior Modification dog trainer and dog behavioralist. Here at The Happy K-9, we train dog owners and rehabilitate/educate dogs. We have trained hand in hand with the two top dog trainer in the east and west coast, with Sean O’ Shea, owner of The Good Dog in California and who is also one of Cesar Millan’s personal hired trainers in Cesar’s “highly-acclaimed seminar ‘Training Cesars Way’”. On the East Coast we have trained with Jeff Gellman, owner of ‘Solid K-9 Training’ who has many awards for the best board and train facility and is very well known for rehabilitating dogs that are marked ‘red zone’, overall a fantastic man and dog trainer/behavioralist. I made my way up to Nova Scotia, Canada for a shadow program with Ted Efthdyimiadis from Mango Dogs one of the best trainers in the industry dealing with rehabilitating dogs with real genetic aggression, dog aggression, human aggression, resource guarding, etc.

We have trained with the best which is why is we give people the best results.

Nelson and the Happy K-9 were a godsend for us. They changed our super leash and dog reactive pit-lab mix into a calmer, more relaxed, fun loving pup.’ So much of the training was not just for our dog, but also for us, to be able to handle her correctly. Setting boundaries, leadership and goal directed training from THK-9 have changed how we interact with our dog now. We never realized what a good doggie we had till Nelson introduced us to Maggie 2.0. THK-9 board and train facility have made us able to keep our super high energy pitty in an engaged environment as we work super long hours. Having a trust worthy dependable team that pick up and drop off our pup and are super accommodating to our crazy schedules, is an amazing blessing ! The best part is despite knowing he’s busy will his BIG pack of dogs, somehow it always feels like Nelson treats our pup special (I’m sure all his clients feel the same way). Can’t say enough good things about Nelson and his team! ”
