About Us

We put high demands on our dogs in today’s modern society. We ask them to be our friends, guardians, playmates, exercise buddies and social extensions in the community as a whole.  We want them to be patient, obedient, and loving. Be comforting to us when we feel blue, leave us alone when we are busy, take new experiences in stride and always be ready to engage on our terms at the time and place we choose. It is quite a tall order. Many dogs do this just beautifully, but just like people, some struggle at times with stress, anxiety, fear and a hard time adjusting to new environments and overall demands put on them. Sometimes it is due to who they are as individuals, but it can also be due to past experiences or lack thereof. We are fortunate that our canine companions are generally very adaptable. Still, some dogs do need some extra help. The good news is all dogs can improve with professional guidance, and this is where Positive Dog Solutions comes in.

Positive Dog Solutions has a great advantage in that while we collectively have decades of experience in the field of dog behavior, we are also skilled communicators and human coaches. We build strong bridges in all levels of human and dog-human relationships. Curiosity, communication, support and empowerment are cornerstones for how we work with dogs and people alike. We will work with you to create a tailored plan to address the challenges you face.
