I think I've told this story before, but it must have been about 13 -15 years ago (time flies when you're having fun :rolleyes:) my sister left her labrador, Prince, in kennels whilst she was away on holiday.
Prince was hip scored (and had been eye certificated, although whether it was up to date, I can't remember) anyway, the kennel maid apparently failed to lock his kennel after exercising & feeding him and he "must have followed her home" and mated with her family's lab bitch before the family could stop it

!
Because the family had asked before to use Prince & sis had refused because the bitch hadn't been hipscored and wasn't a particularly "good" type of lab, she refused to sign any papers for the stud - as she said she didn't witness the mating - and refused a stud fee. The family told everyone however that the sire was her dog and that because it was an accidental mating no papers would be available - but they sold all the puppies.
Prince was used once more for a planned stud and was then neutered - Sis was really cross and wanted to ensure that it couldn't happen again.
The kennel maid lost her job - apparently kennel owners didn't want to risk it happening again and she was dismissed for lack of care - and the village had something to gossip about for a couple of months!
