It must also be people's choice of dog. I can't imagine an over representation of spaniels, Labs or Golden Retrievers amongst the 'menacing people' thing.
The attitude of a dog generally reflects the attitude of its owner and how it has been raised.
Savage dogs are often found in savage families.
I do believe some breeds have stronger inherent tendency toward aggression, but almost any puppy can be trained to not be aggressive.
Yup. Our dog scares the hell out of any delivery people. They refuse to come to the door.
He wouldnt hurt a flea tho. (Hence why hes getting eaten by them atm, sigh)
Once you've been introduced, hes a big slobbery goober. Say hi to our stupid lab. Aggressive as a tadpole.
Our recently deceased and much missed Hungarian Vizsla put on a good show, but if you had wanted to burgle the place, bringing biscuits would probably have secured his assistance in carrying our stuff out to your van...!
