Ulrike S. Reinisch, DVM  

Ulrike S. Reinisch

Born and raised in Massachusetts, Dr. Reinisch earned her Veterinary degree from Tufts University School of Veterinary Medicine in 1991.  She started her training in animal behavior as a doctoral student at the Ludwig-Maximilians University in Munich, Germany, where she completed her internship in small animal medicine.  Dr. Reinisch returned to the United States where she completed a residency in clinical animal behavior at  UC Davis School of Veterinary Medicine in California.  She worked as a behavior consultant in a private veterinary referral hospital in New Jersey before moving back to Connecticut.  

As a behavior consultant Dr. Reinisch's approach differs from a trainers general approach to behavioral issues.  While a trainers focus is on teaching pets how to act,  Dr. Reinisch first seeks to understand the underlying emotional and physical reason for the unacceptable behavior.  She will then work to change behavior by altering the way your pet feels about problem situations. 

Dr. Reinisch has successfully treated hundreds of pets with behavioral issues, and has experience managing all types of problem behaviors in small animals. By helping you to understand your pet's problem behaviors and teaching you how to change them in a non-confrontational fashion, she strives to improve your bond with your pet and your pet's quality of life.
