I was talking about rock dogs.
As an example,a few years ago in company with a keeper and local terrierman in the Dales,what i can only describe as the the East side of Everest and the terrierman saying put a dog in there just below that hawthorn,walking at least 120 yds further along another dog was entered,those two dogs had to work that between them,impossible for one terrier,nigh on impossible for two,the old lads owned better rock working fox dogs,not the full on breeze blocks now that would struggle in spots like that.
Yes I know the score with working the rocks,was brought up on it.
