Angela Summers, VMD

Dr. Summers is very interested in canine behavior. While earning her degree, she worked in the Behavior Clinic at the Veterinary Hospital of the University of Pennsylvania.

She feels that this can often be avoided through proper training and behavior modification as the problems develop.
