Behavior Modification (BM)

Behavior modification consultations are no longer being offered


Unwanted Behaviors

I will partner with you and your family to develop a highly customized and practical training plan, that utilizes current canine behavioral science, to successfully modify your dog’s unwanted behavior(s).  These include, but are not limited to:

  • Fear and anxiety issues
  • Barking, digging, destructive behavior, inappropriate eliminating
  • Difficulty with handling or restraint for nail trims, grooming, etc
  • Aggression:  towards dogs or unfamiliar people, aggressive displays during walks (leash reactivity), aggression in the home, nipping and biting, moderate resource guarding
  • Fear, anxiety and/or aggression at the vet office
  • I work with dogs of all ages and histories, from puppies to rescued seniors

    What's Involved In Modifying Unwanted Behaviors?

    Canine behavior is highly complex and every dog is an individual.  A behavior modification strategy that works well for one dog may not work for another; that is why it’s best to develop a customized approach for modifying your dog’s unwanted behaviors. 

    The best way to develop a customized approach is to schedule a behavior modification (BM) consultation.  During this BM consult, we will review the detailed history of your pet's behavior including all circumstances and events that could be triggering the unwanted behavior(s).  We will then discuss different behavior modification strategies and work together to develop a customized approach and training plan all members of your family feel they can commit to executing.  We will wrap up the session with any pertinent training demonstrations and discuss any remaining questions. You will also be given detailed written instructions outlining the plan we discussed, typically within 48 to 72 hours after the consultation appointment.

    If you'd like to learn more about the role of a Behavioral Consultant, click here to read a nicely articulated blog on the AVSAB (American Veterinary Society of Animal Behavior) website.  The blog provides a much more in-depth description of the process required to develop and implement a successful intervention. 



    The BM (behavior modification) consultation typically requires 1.5 to 2 hours to complete and they can be held in the client’s home or in Phoenix MD at the trainers facility.  Because of the amount of time involved in preparing for the consultation, time spent with the client, and time required to write the customized and detailed instructions for the training plan, the cost of the behavior consultation is as follows:

    • $195 for the initial 1.5  to 2 hour BM consultation appointment
    • $95/hour, pro-rated, for any individual follow-up private training sessions 
    • Packages of follow-up private training sessions are available for a discount:  3 x 1.0 hour sessions for $255  or  5 x 1.0 hour for $399.


    HTDT LLC consultation fees are based on our expertise, individualized treatment plans, length of appointment, and follow-up support.  They are comparable to those of other behavior consultants with a similar educational background and experience in behavior modification.
