Elliot GRFX

Elliot Rosenberg

Owner/ Head Dog Trainer/ Dog Behaviorist

Born in Long Island, Elliot Rosenberg is a Certified Master Trainer and Behaviorist who joins positive reinforcement with balanced training methods to instill trust and respect in the dogs he trains.

For over 10 years he has rehabilitated and trained hundreds of happy dogs to compete professionally in obedience, tracking, herding, agility, and protection sport. Fostering a lifelong love for learning how dogs communicate, he coaches dog trainers and pet parents on basic and advanced obedience, search and rescue, and behavior modification.

Previously Elliot spent 7 years in Costa Rica training high-drive (working) dogs in a variety of dog sports. But his passion remains with owners who are desperate for help. Highly skilled in the diagnosis of behavior issues in dogs with aggression, fear, and separation anxiety, Elliot puts together specialized individual programs to tackle each problem.

Elliot holds a B.A. degree in Psychology from Queens College. His best pet memories are of his Dutch Shepherds, Momba and Sergeant, whom he trained in elite search and rescue, and his German Shepherd, Troy Hartis, who he competed with internationally in Schutzhund and IPO/IGP dog sport.

Jake GRFX 1

Jake Muller

Head Dog Trainer/ Dog Behaviorist

Jake Muller is a Certified Dog Trainer from Oceanside, whose family has been raising award-winning show dogs all his life. Surrounded by these skilled trainers, understanding dogs became second nature, which is why he has spent the last 5 years working with dogs to help improve their behavior and help them live happier lives.

Working at K9 Mania Dog Training, Jake has touched the lives of so many fur parents by helping them with their dog’s behavioral issues. Thanks to his presence at our dog training facility in Deer Park, Long Island, he helps transform even more lives along with everyone else on the staff.

One of the recent families he’s helped is a German Sheperd Collie mix named Solo that struggled with crippling anxiety. Before meeting him, Solo used to refuse to leave the house and would bite his owners without warning. His owners were struggling to administer medication to calm him down and were even considering putting him to sleep. But after 3 weeks of training with Jake and the K9 Mania Dog Training family, Solo is now almost completely off his medication and is even willing to go on adventures with his family.

“I believe the most difficult behavior I’ve helped work with are fear and anxiety. There are dogs whose fears are so crippling that anything out of their comfort zone completely shuts them down. For some dogs, moving away from that kind of fear can be a very long process, while other dogs can overcome fear more quickly with the right support. You can never know how long this process can take. My advice to everyone dealing with that kind of crippling fear is just to be patient.” — Jake’s advice for working with fearful and anxious dogs.

To Jake, the most rewarding part of being a dog trainer is changing the lives of dogs AND their owners. Seeing the owners go from miserable to living the happiest life possible with their dog makes all the work absolutely worth it.

His approach to teaching is supportive, practical, and friendly and has earned the trust of many fur parents. Jake is a balanced dog trainer and uses all training methods at his disposal to achieve the best result. He believes that every dog is different and that every training style is unique to every dog.

Training is a complicated process, and it can be frustrating for dog owners when the usual methods don’t work. Jake’s advice for dog owners is to simply ask for help, get educated, and exercise patience. By seeing and learning other training methods, dog owners can find out what training style suits their dog the most.

Jake loves boxers, partly due to his admiration and respect for his grandmother’s work with them in dog shows. He considers them an extremely intelligent and fiercely loyal breed.

“I love all the different personalities dogs have and the bond you can create with them. They have so much love they can express for everyone.” —- Jayden, on what he loves about working with dogs

One of the things that Jayden likes to do when handling dogs is to stay calm and composed. This, combined with a slow and steady approach, helps put dogs at ease and gives them a chance to get used to his presence at their own pace. Once he builds that initial level of trust, he then uses treats and pets to help make them feel loved.

He’s absolutely smitten by the charm and personality of pitbulls. He finds their big personalities and funny energy endearing.
