My dog is Patterdale crossed with jack Russell….hilarious dog, all the energy of a Jack with the Patterdale just taking the edge off the snappiness….but as others have said, Patterdales are equally as tenacious if the mood takes them, he once spent all day…yes all flipping day…digging a rat out from under the shed in the garden…wouldnt come in for food, just totally focused on the task in hand, got the rat in the end the little minx!
Nice size too, bigger than a Jack but smaller than a Lab, black with white chest and paws, stunning….i’d happily have another, luckily a breeder near us specifically crosses these two dogs for this end result.
