Abstract
The American College of Veterinary Behavior has grown in number and in expertise over the past quarter century. There are now 86 diplomates, at least three textbooks on treating behavior problems, and a text on veterinary psychopharmacology. Although veterinary behavior began in veterinary colleges, the majority of residents are now trained in non-conforming programs. Many more diplomates practice privately in specialty clinics or as separate businesses. Progress has been made in both diagnosis and treatment with polypharmacy, resulting in successful outcomes for many dogs and cats suffering from separation anxiety, fear, or aggression.
