We had one when the children were small, he hated them going out of his sight, used to round them up. He was also an escape artist and was well known round the town, he would go to the pub, turn up at the school and wait for the children coming out. We had a six foot high wooden fence with a rail at the top as suggested by the dog warden and Findlay still could climb it
As there were always children coming and going it was hard to keep him in so we decided reluctantly to rehome him , they kept him for 5 days and brought him back as they couldn't cope.
He did eventually settle down and was with us till he died at 14 yrs old.
