is the big enchilada, the United Kingdom's registry for working sheep dogs. Unlike the USBCHA
, the ISDS both registers dogs and puts on trials. (Imagine a combination of the ABCA
and the USBCHA in the United States, add about fifty more years of history, sprinkle in some UK flavor, and you'll have the ISDS). The ISDS is responsible for the four national trials held every year in England, Ireland, Scotland, and Wales, as well as the great International Sheepdog Trial, rotated every year throughout those four countries. The International is considered the premier dog trialing event in the world.
