Ratter (dog)

A ratter is any dog used for catching and killing rats and similar vermin. Specialized rat-catching breeds are found in many countries. A typical ratter is small to medium-sized and has a short and smooth coat, however a wide range of dog breeds and landraces may be used. The use of ratting dogs is widely considered to be the most environmentally friendly, humane and efficient methods of exterminating rodents. Ratting dogs are considered more efficient than domestic cats.
