​​I started By Your Side Pet Behavior Consulting to offer compassionate, specialized support to pet guardians struggling with complex behavioral challenges. I want to help you and your pet find joy in companionship.
​
My practice specializes in these key areas:
-
Feline Behavior Consulting: For all aspects of cat behavior - from setting up the environment to support natural cat behavior to litterbox issues to aggression between cats.
-
Canine Fear & Anxiety: Dedicated support for dogs dealing with fear, anxiety, and trauma-related behaviors.
-
Setting Your Pet Up for Success: Proactive guidance and early intervention plans to build a strong behavioral foundation from day one.
The Kitten Rescue that Launched a Profession
​​My lifelong love of animals changed dramatically in 2007 when I rescued and hand-raised a neonatal orphaned kitten. This experience shifted my perspective and sparked a curiosity to learn about feline behavior. I began a dedicated study, learning to appreciate cats not just as pets, but as complex individuals with unique emotional and behavioral needs.
​
I have worked with cats professionally since 2013 and am proud to be one of just a handful of IAABC Certified Cat Behavior Consultants in New England.
From Fearful Dog Guardian to Specialized Consultant
My professional journey took another turn when a fearful dog found me. The struggle to find professional, empathic behavioral support and guidance for her was frustrating and isolating. I came to realize that most dog training professionals were not well-equipped to deal with extreme fear and anxiety, Driven by a need to help my dog —and other dogs and guardians facing similar challenges—I expanded my education and practice to focus on helping dogs with fear and anxiety.
​
​My professional experience includes specialized field work in animal rescue and behavioral support. Since 2018, I have been a member of the ASPCA's national behavior response team, collaborating with professionals from across the country to rehabilitate animals rescued from cruelty and neglect situations. I maintain a deep commitment to helping animals who have experienced trauma heal behaviorally through my continued work with both the ASPCA and Humane Worlds for Animals (formerly HSUS).
​
As a certified professional behavior consultant, I am committed to upholding ethical standards and participating in continuing education to stay current on the latest research and standards of practice.

Karen…understands what pups need to feel safe in their environment. Her methods were kind, self-esteem building, and realistic for our living situation… She was very thoughtful in observing [our dog’s] behaviors and made sure we were setting him up for situations where he could be successful….I would readily recommend Karen to any pet owners who are looking to improve both behavior and attitude and foster a healthy human/animal bond.
