i will say in my experience the hardest dog i ever seen was a fell terrier some would say too hard the second was a pat nutall breed 1/8 bull the thing was pure evil the only reason i say fell first is the dog never backed down
to anything he was put to, where as the pat would use its head after taking a pasting lol the pat was a dog fighter to but never had the pleasure of owning a lakie like i said just my experience no doubt others will have difference in opinion i think its in the dog or not simple as that any how all the best to one an all for the coming season. regards lee.
