Eric started his career volunteering at a local boarding kennel in St. Louis, Missouri when he was 15 years old. He continued as an apprentice for their training program and instantly fell in love with dog training. Eric went on to study Animal Behavior at Meremec College in St. Louis and shortly after started Happy Puppy Dog Training. In 2008, Eric moved to Los Angeles to further his career with hopes of shedding light on a more positive, humane, and scientific way to train dogs.

In addition to Happy Puppy, Eric also devoted his time to rehabilitate dogs in need, specifically German Shepherds at the Westside German Shepherd Rescue. As a foster parent, he found great joy helping dogs that displayed fearful and/or aggressive behavior pass their temperament tests so they could be placed in a welcoming home.

Along the way, Eric came across an 8 month old German Shepherd who had some behavior issues and unfortunate history. They formed an instant bond and the shepherd was later adopted by Eric. After a rehabilitation period, the lovable shepherd, now named Archy, was playing with other dogs, rolling over for belly rubs and off-leash hiking.

Eric has had the opportunity to see this transformation in many dogs he has worked with throughout his career and has even had the chance to provide his services in the United Kingdom and France. Regardless of culture, dogs learn in the same way all over the world. He continues to learn and his only wish is that we could live more like dogs.

Currently, Eric is an American Kennel Club Canine Good Citizen Evaluator, a member of the Association of Professional Dog Trainers (A.P.D.T.), and the International Association of Animal Behavior Consultants (I.A.A.B.C).

Rashi Khanna Wiese – Operations

Rashi is a social worker with a knack for business and technology. After graduating from Boston University with her Degree in Psychology, Rashi attained her Master’s Degree in Social Work from The University of Southern California. There, she pursued a unique concentration focusing on mental health as well as emotional intelligence and organizational development. This concentration allowed Rashi to utilize her knowledge of behavior and psychology, implementing positive changes in the business world.

After her studies, Rashi worked in the digital and mobile advertising world for over 5 years. In 2014, Rashi met Eric and learned of Happy Puppy and the positive reinforcement training methods utilized. The logic behind these methods were similar to methods she learned throughout her studies.  As she learned more about Happy Puppy, Rashi became fascinated with dog psychology and how it could be applied to human psychology. Combining the passion for behavior and her knowledge of business operations, Rashi soon became the backbone of “Happy Puppy” (and Eric's wife!).

From strategic partnerships and marketing to social media and website design, Rashi is heavily involved in our day-to-day operations, keeping everyone connected. Through her work with Happy Puppy, Rashi hopes to positively impact the lives of animals, just as she hopes to change the lives of others through her social work. Rashi is especially excited to participate in pet therapy and the rehabilitation process.

The Happy Puppy T‍‍‍eam


Born and raised in Tennessee, Mike cannot recall a time in his life that did not involve dogs. It started with Amos- Mike's mother adopted a Dalmatian puppy when Mike was five years old. This was Amos, and it's impossible to explain Mike's connection to dogs without talking about him. Amos was one of the main reasons he and his mother embraced a belief that has been at the core of Mike's life ever since:  that family was not and would never be a species-exclusive word.    He continued to become more involved with dogs- pet sitting around the neighborhood and dog walking. It wasn't until his senior year of high school that he became very interested in dog behavior. A special opportunity in his Ecology class offered the next step in understanding: getting to visit a small wolf pack being fostered in the Tennessee Hills around his home. During the visit, Mike finally recognized movements in the wolves that he'd been seeing in dogs for ages.  

He volunteered with the wolf pack until they were relocated. Mike also continued to study dogs on his own, but it wasn't until LA that he received the chance to really learn from them again. In 2007, he became an employee of a dog care/training facility in East LA. The job started slowly, but soon Mike was tossed into the deep end. Over the next two years, Mike learned more about body language, communication, and problem solving than he had anywhere else. Each dog presented a new lesson- the most important through-line of them all being Patience. He became involved in rescue efforts ranging from: relocation of rescue dogs to community events stressing the importance of spay and neutering  From 2009 to current, Mike applied the lessons he learned at the dog car facility to more pet sitting and walking, as well as assisting volunteers at his local shelter.

In 2012, Mike was finally introduced to Happy Puppy's positive reinforcement training- and there has never been anything else that made so much sense. He had the great fortune of shadowing Eric for a year. It reinforced ideas he already had while showing new pathways to communication. He currently specializes in the Board and Train Program- taking dogs into his home to give a tailored, one-on-one evaluation and training approach. Currently having no dogs of his own, Mike is free to adjust his environment to whatever his clients might need. While continuing to do Board and Train and Private Lessons, Mike also got his AKC Canine Good Citizen Certification.  He is pursing APDT certification as well as assisting with the RESORT.  Mike has met and helped with challenges ranging from Separation Anxiety to Leash Reactivity, Potty Training to Fear Issues. Amos would be proud. ;)

With a Biology Degree from UCLA, Aracely initially wanted to pursue a career in field research. In 2017, she took a life-changing position studying birds in the Dominican Republic. It was there that she realized her true passion lies in animal care. She soon missed volunteering at her local animal rehabilitation centers and sought out to volunteer at the only vet clinic in town to fill that void. Upon her return, she resumed her volunteer work and was convinced to pursue a career in veterinary medicine. She had once again ignited that passion she had as a child to work with animals.

Along ‍‍‍her journey to a career in animal care, she found Happy Puppy L.A. She is eager to learn more about dog behavior from the great mentors she has found at the RESORT and she is confident that her interactions with the Happy Puppy staff and guests will provide a great foundation for her future career with animals.
