more than likely s parkin. ive had a few of his terriers. they have all been decent enough fox dogs. but they dont all come small. . i agree that breeding smaller workers is difficult. and a lot of big terriers that are raved about are just bullies that get found out once they are up against it. or when you breed down in size the offspring arnt up to the standard of the stronger sort. . but it has to be remembered that weak terriers are not generally up to much either. shouldnt we be breeding for something inbetween the two. and passing on the smaller or oversized to folk that they suit. bre
