Rottweilers have a pretty bad reputation. With their vicious bark and sharp teeth, they make for excellent guard and police dogs.
But now a Benedict Arnold in the Rottweiler community is blowing everyone's cover.
He was caught red-handed for utterly adorable behavior in this YouTube video which shows the dog approaching a group of cows.
The cows are understandably wary of the newcomer -- but after a couple of sniffs and plenty of tail wagging, the Rottweiler shamelessly allows the cows to lick and nuzzle him.
His friends must be so embarrassed.
