Our Approach

Our approach is to teach owners how to teach, guide and navigate their dogs to success. We do this by providing one-on-one lessons that are customized for each dog and owner.

 

Owners will learn how to:

  • Train and work with their dog
  • Change behavior & manage behavior
  • Understand their dog and why their dog does what he/she does
  • Set their dog up for success in & out of the home
  • Create clear and consistent rules & boundaries
  • Develop a lasting and enjoyable relationship

Training is provided using positive reinforcement-based methods and a LIMA approach (Least Intrusive, Minimally Aversive)

Benefits of Positive Reinforcement & LIMA Training

What is Positive Reinforcement?

Positive reinforcement means reinforcing your dog for doing the right behavior. When teaching a dog skills, we want to reinforce their behavior. When a behavior is reinforced, it is likely to be repeated. Reinforcement can be in the form of treats, toys, praise etc. Through clear reinforcement, practice and consistency, the goal is to get your dog to respond to cues with little to no food.

What is LIMA? 

LIMA is an acronym that refers to "Least Intrusive, Minimally Aversive." Trainers and behavior consultants who follow the principles of LIMA, use this framework to decide how and when to use different training & behavior techniques and interventions in order to provide the most success possible. Click here to learn more about LIMA.

Benefits

✓ Proven results for both training & behavior modification for dogs of all ages and breeds
✓ Training becomes enjoyable for your dog as he/she gets rewarded for a job well done
✓ Teaches skills while setting boundaries and rules in a clear and consistent manner
✓ Fosters a powerful relationship between the dog & dog owner using a friendly & humane approach

Professional Testimonials

I have referred countless dog guardians, as well as dog pros to Anthony, as I truly trust his talent and knowledge to work with a wide range of behavior problems, especially in aggression cases. He is professional and compassionate with both the humans and animals that he helps, and is genuinely talented at working with “both ends of the leash.” Whether you just adopted your first puppy, have a behavior issue or you have been training dogs for years, I can highly recommend Anthony as a wonderful resource for all your dog training and behavior consulting needs!

Micheal Shikashio, CDBC
Founder of Aggressivedog.com

Anthony DeMarinis has quickly risen to the top of the dog behavior field, consistently proving himself to be one of the most ambitious, dedicated, passionate, insightful, and competent professionals in the dog training world. It has been a personal honor to mentor him, have him be among the first Licensed Family Dog Mediators in the United States leading a paradigm shift in the profession, and to be able to call him a friend.

Kim Brophey, CDBC, Applied Ethologist
Author of Meet Your Dog
Founder of L.E.G.S. Applied Ethology Family Dog Mediation Course

Anthony De Marinis is a highly educated and skilled behavior professional who I am privileged to call a mentor. No matter how much education one has, making the jump to more complex behavior work can be intimidating without qualified support. Support doesn’t get much more qualified than Anthony with his impeccable credentials, immense education and training, and extensive experience. If all that wasn’t enough, he is kind, open-minded and easy to talk to. I’m grateful technology makes it easy to access long distance support, and if you are looking for an extra set of eyes on a case, a second opinion, or even help creating a plan, I recommend Anthony without hesitation!

Shelly Wood, KPA-CPT

Anthony was instrumental in offering me feedback when I was first getting started with my private dog training business. As aggression is not my area of expertise, Anthony helped me work through two challenging cases. Anthony acknowledged my own experience and included that in his strategy with both cases. It comes across in his communication that Anthony is passionate about his work. His interpersonal and dog training skills are top notch. Anthony is not only a problem solver, he enjoys connecting with other professionals. He is open to listening and sharing ideas and strategies, something we need more of in the dog training world.

Graham Buck
Buck's Best Dog Training

I refer to Anthony regularly and I also regularly consult with him when I need advice, a different point of view or just someone to talk a tough case through with. Anthony is always kind; responsive and most importantly, I walk away with great ideas and options to help my clients. Whether you are looking for basic skills or have a serious behavior issue, I highly recommend Anthony and have the utmost confidence in him.

Linda Keehn CDBC, CPDT-KA, ADT, DN-DBC, CSAT, FDM
Certified Dog Behavior Consultant- IAABC

As his first mentor, I have known Anthony since he started his journey as a dog trainer and behavior consultant. He has quickly become a very accomplished and gifted dog professional. He is an avid questioner and learner who has amassed a deep and wide range of skills. He has demonstrated his ability to teach those skills to his clients, and he brings kindness, a sense of humor and emotional intelligence to everything he does.

Vivian Arzoumanian, CDBC, CPDT, CBATI, PMCT2
Certified Dog Behavior Consultant- IAABC

I connected with Anthony via a dog training group we are in. Over time as I have gotten to know Anthony better, I have sought his help with behavior cases including one of my own dogs and dogs of clients. I am grateful for his expertise and help!

Elizabeth Droke, ADT-IAABC

I worked with Anthony virtually to consult for behavior issues like fence barking and fence reactivity for my senior Golden Labrador, Kai. He was very thorough with my case and took the time to provide effective strategies that were not previously suggested by the other behavior consultants and trainers. As a positive reinforcement based dog training professional myself, I highly recommend Anthony and his team for training and behavior needs.

Shelly Haines

I turned to Anthony for help with a greyhound NJGAP placed. She was exhibiting some fear based behaviors and has anxiety. We had our initial consultation(virtually) which lasted over 90 minutes via Zoom. I highly recommend Anthony to anyone needing help. He was responsive, thorough and caring.

Recent Client Reviews

“Anthony is the best! My 2.5 year-old rescued Pitbull, Ace, was displaying resource guarding and aggression. After working with Anthony for a couple of months both over zoom and in-person, Ace has improved so much.”

Brittany A.

“My husband and I worked with Katie Cameron of De Marinis Dog Training for our puppy and had a wonderful experience. Katie was patient and understanding as this was our first time having a puppy and she really took the time to work with us at our own pace. Katie taught us so many great games and techniques that helped us get our puppy on track to be a great family dog.”

Jyothi T.

“We LOVE Anthony! He helped us so much with our two special needs rescue pups, even coming over to accommodate a crisis late on a Friday night. He’s so passionate, he’s so knowledgable, he genuinely cares about the animals he’s working with.”

Kendall B.

“Katie was INCREDIBLE with our puppy Westie. We would surely have been lost and struggling had we not called De Marinis Dog Training when we did. Katie was thoughtful, caring and customized each lesson to our needs.”
