Ratter (dog)

From Wikipedia, the free encyclopedia
(Redirected from Rat terrier)

A ratter is any dog used for catching and killing rats and similar vermin. Specialised rat-catching breeds are found in many countries. A typical ratter is small to medium-sized and has a short and smooth coat.


The Guinness Book of World Records lists as the "fastest canine rat catcher" a bull-and-terrier dog named Billy, who killed 100 rats in 5 minutes 30 seconds (average of one rat every 3.3 seconds) at an event in 1825.[1] Guinness also credits Billy with having killed 4000 rats within a 17-hour period (average of one rat every 15.3 seconds) on an unspecified occasion;[1] other sources, including the 1993 edition of Atlas of Dog Breeds of the World, credit him with killing 2501 rats within a 7-hour period (average of one rat every 10 seconds).[2][3][4][5][6]
