Aggression is not a diagnosis ... it's a symptom of an underlying problem. In this VetVine Case-based Learning (CBL) segment, veterinary behavior expert - Dr. Christine Calder - discusses Gus and shares his story to highlight keys to working through a behavior problem (in this example - aggression), and considerations regarding the work-up, constructing a list of differential diagnoses, and a five-pronged approach to treating the patient. Discussion includes when to consider implementing medications as part of the treatment plan as well as medication selection.
