What is it about the black terrier as a working dog that reflects poorly on the average terrierman nowadays? So a border lakey requires more knowledge to enter? Back in the day lads were entering them at 8 month old carelessly and having success, just like some lads do with the ‘idiot’ proof blacks. It’s not knowledge that’s restricting the border lakey success, it’s access to good blood. If you have good blood, regardless of the breed, the odds are in your favour assuming you enter your dog properly.
