I had a patterdale APPARANTLY from spartacus lines and few other names, got him from 8 weeks old.. Was fine up untill 4 months old then he became very nervous to the point where you couldnt even road walk him, very scared of people etc... BUT when i used to take him out down the fields he was completly opposite . Very head strong. Once on a scent he coulmt be called off and wouldnt come out of cover/bush.
I have to agree with an earlier thread i read somewhere he was really a one man dog
