A dog at the centre of an international campaign to save it has been put down, Belfast City Council has said.
The council said that Lennox, an illegal pit-bull terrier type, has ''been humanely put to sleep''.
A former Metropolitan Police dog handler claimed the dog represented a danger due to his unpredictability.
His destruction was ordered by the Court of Appeal last month.
Lennox was impounded by Belfast City Council's dog wardens in 2010.
He was owned by a woman whose family claimed he was not dangerous, but while it was unclear exactly what breed he was, pit bulls and dogs like them are illegal in Northern Ireland.
In June, Northern Ireland's most senior judges rejected Caroline Barnes' legal bid to overturn an order for the destruction of her pet.
Two lower courts had already ruled that the dog should be put down.
First Minister Peter Robinson suggested that the dog should be re-homed after an internet campaign for his reprieve went viral.
Campaigners claimed to have attracted 200,000 signatures in support of a reprieve.
Staff at Belfast City Council have been the target of intimidation by some supporters.
