What is behavior modification?

Behavior modification is a treatment approach for changing the undesirable behaviors that your dog exhibits. Behavior modification uses counter conditioning and desensitization approaches, a variety of training skills as well as implementing management and safety protocols. Behavior modification can address a broad range of issues. After discussing your dog’s issues and learning why they might do the things that they do, plans and protocols are created to help manage and modify the behavior(s) of concern. Behavior Modification programs are designed to meet the specific needs of each dog and household. Services typically take place in your home, however services can also be provided at other locations of your choice. (Online Virtual Behavior Sessions are also available).

Behavior Modification addresses issues such as:

  • Aggression to people, dogs and other animals
  • Reactive behaviors on walks, such as barking and lunging
  • Generalized Anxiety and/or Fear
  • Resource Guarding and Territorial Issues
  • Fear of noises, people, other animals, and storms
  • Aggressive, reactive and fearful behavior towards children
  • Difficult Decisions: Consulting on difficult situations and potential outcomes
  • Separation Anxiety and other issues when home alone
  • Destruction
  • Excessive attention-seeking
  • And Much More!

During the Comprehensive Behavior Consultation, we will:

  • Get to know you and your dog with an in-depth & thorough behavior history form
  • Discuss your goals and concerns to develop a plan
  • Introduce training concepts
  • Provide helpful suggestions and information
  • Observe and evaluate your dog
  • Discuss options for behavior modification and how we can help

Helpful tips for behavior change

Upload Video Footage

If you have any videos of the problem behaviors, it is helpful to upload them to your computer. You can also upload a couple of videos where your dog is just being him/her self, regardless if it shows any of the behavior issues. If possible, please upload videos on Youtube and make sure to select it as “Unlisted” so that it is not public. Once your appointment is scheduled, you can send Anthony an email with the links to each video. You can also upload video to Google Drive if you prefer. If none of these options work for you, just save them to your computer and Anthony can share the screen view option together during the consult. All videos will be reviewed together during the consult. If you do not have video footage of the issues, do not worry. It is NOT worth trying to provoke your dogs behavior or put yourself or your dog in harms way for video footage.

Keep a Behavior History Journal

In a notebook, you should be writing down specific incidents when the problem behavior(s) happens is key! You should also include what happens before and after the behavior(s) as this provides valuable information. Include as much detail as you can.

Understand What Your Dog Is Saying

Our dogs are constantly communicating through their body language and behavior. Understanding canine body language and communication signals is important because it can help us learn about how our dogs are feeling and why they are doing the behaviors they choose to display. Taking the time to learn about canine body language and communication signals is the first step in treating any behavior issue. Here are some credible sources of information to learn about canine body language and communication:

Client Testimonials

“I can’t say enough good things about how Anthony has helped our very fearful and neurologically compromised foster dog, and us. Her behavioral issues are complex and Anthony has addressed each and every one of them in a knowledgeable, patient, thoughtful and methodical manner. I have learned so much from him.”
Dana S.

“Anthony came highly recommended from a veterinary behaviorist in New York City. I have a young, out of control labradoodle with debilitating separation anxiety. When I got her, I was no longer able to go out for errands, dinner, or even go to work because she would bark constantly for 12 hours straight if I let her. Anthony gave us our lives back!”
Katie A.

“Force free behavior modification was the only method recommended to us by our Vet as well as the rescue organization that we got Luna from. Anthony is exceptional! He is very professional, compassionate, patient and a wonderful teacher. Needless to say, we highly recommend him!”
