Evaluation & Treatment Program Session

I believe it is imperative to provide the best possible quality care of your dog and most effective, permanent treatment as quickly as possible including the most severe, complex cases and those failed at previously - all dogs welcome!

For 20 years I have specialized and become a recognized expert in preventing dogs from being given up due to behavior problems that CAN be effectively treated, keeping countless dogs and owners happy and harmonious together for life - my life mission.  Together using my created, proven, trademarked Total Harmony Dog Transformation® System we can release you and your dog from the prison of a behavior problem(s) no matter how severe, complex, if multiple problems and regardless of how many methods you have tried previously, while attaining the ultimate level of communication, love and harmony between you and your dog!

Every Dog Behavior Problem Effectively Treated including multiple simultaneously:

  • Aggression. All forms of aggression resolved including leash aggression, resource guarding, inter-dog aggression, touch aggression, territorial aggression, stranger aggression, possessive aggression and more.

  • Fear/Anxiety. All forms, reach out to me if your dog is exhibiting any signs of fear or anxiety including separation anxiety, fear of people, fear on walks, fear of noises or sights, touch anxiety, fear of car rides, vet, or anxiety caused by changes such as moving, new baby to home, divorces, or similar transitions. 

  • Fear Aggression. This focuses on effective treatment of all behavior problems that result in the combination of both fearful and aggressive dog behavior. 

  • Rehabilitation. As a Shelter Dog Expert I rehabilitate all dogs with histories of abuse, neglect, and severely impoverished backgrounds such as puppy mill dogs. 


I understand you and your dog are suffering as well as potentially being faced with serious real life consequences that can be desperate. But there is hope regardless of prior failures. From 20 years experience, I can help with real life repercussions that are further pressuring you and understanding the urgency of resolving behavior problems, I treat every case as quickly as possible. Contact me today about your dog to get the real help you and your dog truly deserve.

In person, In and Out Home Real Life Behavior Treatment Program 

Tailored to your Dog, Your Environment where Problems are actually Created and Occurring 

  • I believe it is essential to provide the best possible quality care of your dog and most effective, permanent treatment as quickly as possible.

  • All behavior problems are evaluated and treated in your dog’s real life environment in your home and on your walks from your own home/apt. building and neighborhood (which varies widely between clients), where they are actually created and happening, and not within an artificial re-creation in a facility which can dramatically alter a dog’s natural, occurring behavior and never virtually, cannot train or treat a dog with behavior problems by describing to you. We thoroughly agree with the American Kennel Club that behavior problems cannot be treated virtually.

  • To do so, I travel to your particular location and take on the travel time, cost and effort - at no additional charge to you.

  • Due to its crucial nature, all behavior problem treatment is done with Christina Shusterich, not a lesser accomplished employee!


Completely Comprehensive Behavioral Evaluation &
Treatment Program Session:  2 hours $399. 
Contact me with a detailed description of the problems you are experiencing.


What is it? What does it include?

I Evaluate your dog where the problems are actually occurring to clearly determine all behavior issues, causes, intensity level of your dog’s reactions, triggers and trigger distances of the problem behavior and to specifically tailor my Treatment Program to your dog, yourself and your real environment, dogs acting radically different in different environments.  Additionally, prior to meeting as part of my evaluation I have you complete my extensive detailed questionnaire regarding your dog’s behavior, as well as ask you to provide a history of your dog, both of which I analyze prior to our in person meeting.  

With this extensive diagnostic assessment Evaluation, my Treatment Program is tailored to your dog’s specific problem or multiple problems, to work effectively in your specific living environment and taking into account your lifestyle. Additionally, it includes immediate ways to continuously reduce and treat your dog’s reactivity level calming your dog on a daily basis, begin your Treatment Program, you are taught “Dog Speak” - how to effectively read, understand and predict your dog’s behavior (especially aggression) to change it, and are provided with very extensive handouts to refer to, including my behavior modification handbook.

My acclaimed Total Harmony Dog Transformation® System is designed to treat behavior problems successfully and as rapidly as possible. I work with your dog directly but you participate in order to ensure your successfully handling of your dog when we are finished, as well as to speed the treatment process by providing you with specific homework to work on in between sessions. It is critical to provide you and your dog with relief as quickly as possible from the behavior problem(s), which tend to completely overwhelm your relationship, your life and also often have very serious real life consequences such as eviction threats, dangerous situations and the potential for giving up your dog. The number of sessions depends upon the behavior problem, whether single or multiple problems, intensity level, trigger number and frequency, beginning existing relationship between dog and client and especially client complying with every aspect of the program and practicing between sessions and is discussed after your dog has been Evaluated. 
The fee per session is $235, 1 hour 10 min
