Full disclosure...I am also a veterinarian. Dr. Pachel and his team are a valuable resource for any pet owner dealing with behavior issues for the past 1 & 1/2 years I have personally used his services for my adopted dog with a list of issues. Having an animal with behavior issues is like a roller coaster at times and the Portland Metro area is lucky to have a board certified veterinary behaviorist (there are only TWO practicing clinical behaviorists in OR & WA) to provide expert advice as well as provide owners with resources and APPROPRIATE local trainers that are all instrumental in a behavior modification program. Yes, it may take a while to get an appointment and his expertise is matched by an appropriate fee, but Dr. Pachel's (as well as his technicians) consultation, treatment plans, and communication are top-notch. I do not hesitate to recommend my own clients to the Animal Behavior Clinic. For anyone who has a behaviorally challenging pet, there is often no quick miraculous fix (any person claiming that they can cure an animal of a serious behavior problem, IMHO, is setting an owner up for potential disaster). Managing a pet with behavior issues is an investment of time, resources, and money in order to get the best results and hopefully allow that pet to become thriving member of a family. Unfortunately, not every behavior case will have a happy ending, and Dr. Pachel's recommendations and support in situations like these are invaluable.
