The most dangerous Golden Retrievers are the ones that force you to pet them till your arm falls off...
When they lay their head on your leg and cut off circulation to your foot it’s pretty scary.
But while I have run across a few dog-aggressive field types, I've never seen one human-aggressive. Ever. Sure they'll bark to announce a stranger, and they'll raise a ruckus if they're crated and you approach "their" truck.
But the dog in the telecast is not a purebred Golden - it's a mix. From the prick ears and narrow head I wd say Border Collie - Golden. But it's highly unlikely that a family pet wd be human aggressive to strangers - unless they never have guests and the kids never have anybody over.
