Rat Terrier Starter Care Guide

About the Rat Terrier

Breed guidance describes the Rat Terrier as a compact, tough exterminator dog and playful companion that comes in two size varieties. Owners can provide a controlled prey-free search while fitting the route, equipment and impact to the individual dog's actual size and health.

Breed traits are general patterns, not promises. Individual health, temperament, age, home and life experience still matter more than the label.

Health areas to know for Rat Terrier

The source below highlights patellar luxation, hip dysplasia, heart disease, and primary lens luxation in its breed health-testing guidance. For owners, these are areas to understand and discuss with a veterinarian—not a prediction that this dog is affected, not a complete list of breed risks and not breeding advice.

Ask the veterinarian which source-listed areas matter for this dog's age, history and current health, what changes to watch for and which signs would need a prompt call.

Save any existing result with the named condition or body system, test or examination, date and exact finding so one result is never treated as a whole-dog clearance.

Record new or worsening symptoms with timing, context and a photo or video when safe, then seek veterinary assessment instead of assigning the change to breed alone.

Important limit: The linked source was created to guide breed health testing, often in breeding programs. It does not show how likely an individual pet is to develop a condition, create a personal testing schedule or replace diagnosis; some results describe carrier or risk status rather than current disease.
