A heartbroken dog owner who was forced to put down her "ticking time bomb" St Bernard is urging other buyers to be vigilant. Sharon Herrington, 53, says she had to take action over fears Bear - who weighed 10st - would launch a fatal attack.
The dog had already bitten two strangers and she was worried about the safety of her family. Sharon and husband Cyril Herrington, 65, got Bear when he was one, after his previous owners gave him up due to ill health.
They say he wasn't showing signs of aggression then but, within six weeks, had started lunging at people. The couple - who are experienced dog owners and have had two St Bernards previously - spent more than a year trying to 'fix' Bear.
