Brought up from a baby with GSDs first was a pup from a scrapyard she died when I was 11 next 1 was from 2 doctors that were breeders and showed them she was no good for showing so we got her at a goood price turned out her grandfather was a crufts grand champion . She was a great dog not a bad bone in her body didn't even bark at dust men, post man, or milkman she was daft as a bush untill told not to be. just a big hairy daft lump. Since then I've had a black lab, shelty rehomed her after my my youngest born couldn't trust her, working Border Collie who was over 18 when she died, and now my Lurcher who's 11 at xmas. Best dog of all of them and most trust worthy the Lurcher like the second GSD just a big daft lump, not sure why as he was a rescue and had been miss treated by his first owner who we never met untill we got him at about 7 months old. The only time he is not when he sees or hears travelers. you draw your own conclusions from that.
