What Is Reactive Behavior?

Reactive behavior represents an emotional response to a stimulus (i.e., the sight, sound and/or smell of something) that triggers an abnormal level of intensity (i.e., an over reaction). A common example would be a dog who barks excessively when seeing someone (the “trigger”) walking across the street. Reactive behaviors vary from dog to dog and often include barking, lunging, snarling, snapping, stiffening, hyper-vigilance, alertness, fearfulness and/or avoidance. When dogs become reactive, the overstimulation may cause loss of their conscious control. When this happens, overreactive, frustrated and/or aroused dogs can exhibit aggressive behaviors.

Our Process and How It Works

Initial Consultation (1.5 - 2 Hours): Everyone starts here. During the consultation we will:

  • Learn about your dog’s behavior(s)

  • Discuss your goals

  • Discuss your behavior and training options

  • Create a plan and come up with strategies

  • Implementation of strategies and training skills generally starts during the initial consultation.

Follow-up Sessions (45 min - 1 hour): During the follow-up sessions we will generally start where we left off from our prior session by continuing to build on any skills or strategies that were covered and/or we will introduce additional skills and strategies to continue moving forward with your goals.

*Rates are listed on the rates page.

Our Approach & Philosophy

Laurie, Olaf and Anthony in a reactivity lesson

Laurie, Olaf and Anthony In A Reactivity Lesson

We approach each dog as an individual, helping them to be the best version of themselves while teaching you how to be the best owner for your dog.

As individuals, each dog learns, works and is motivated in different ways, which is why we do not believe in one training method or approach.

Our training techniques and behavior modification strategies incorporate a variety of methods and styles, with a focus on reward-based techniques and play, as we believe training and learning should be enjoyable, motivating, and cultivate a relationship. This is done by using food, toys and play, praise and attention, and/or exploration as rewards.

Lessons are customized based on your goals and who your individual dog is. Our goal is to help you and your dog succeed. Together, we will determine what the best training methods, strategies and tools for your dog and you will be so that you can achieve your goals and live your best lives together.

Frequently Asked Questions

Client Testimonials

“Cannot recommend highly enough. One of our dogs struggles with reactivity, particularly on leash. Working with Anthony has helped us gain a better understanding of our boy’s triggers, how to manage them, and dig deeper into possible causes. Anthony’s expertise and professional training are what attracted us to him. When you work with him, you’re getting much more than a dog trainer. 12/10 recommend!”

.-Amy M.

“I was referred to Anthony by another trainer for aggression and reactivity in my rescue puppy. Since working with him my dog has made tremendous progress. I highly recommend him to anyone with a dog with behavior problems!”

“Without a doubt I would recommend Anthony and De Marinis Dog Training and & Behavior. I have worked with Anthony for our reactive dog (towards other dogs). Anthony has a very calming demeanor that makes an anxious dog owner feel at ease. And he is very easy to talk with and would allow me to video him so that I could go back and review everything we covered in our lesson. I highly recommend Anthony!”
