A Jack Russell Border Collie cross is a relatively new mix of two breeds, the Border Collie and the Jack Russell Terrier. The Border Collie was originally bred to herd sheep while the Terrier was bred to hunt foxes.
For centuries the two breeds were kept apart by physical separation of farms and by social conventions that led people to believe that Crosses would be undesirable in both farm and hunting environments. This segregation ended in 1993 with a single breeding that created Quint, who showed exceptional herding abilities from an early age.
The original intent of this cross’s breeder, Debbie Lopes, was to create an all-around dog suited for life as a working animal.
What does a Jack Russell Border Collie Cross look like?
The physical requirements for the working cross are:
– Height between 24–29 inches tall at the shoulder. Dogs that are extreme in size and weight will not have the speed necessary to herd sheep and cattle, nor will they have the endurance to work all day.
