They normally do what I ask them to do..they would not know..the Command "Bite that person"!! It's laughable....
I've been bit by dogs...three times..that I recall...A GS..when I was s kid..a little POS terrier when I was adult...and my own dog about 4 years ago...
That last one was all my fault.
Ok, no one else in the world knows your dogs. strangers do not know how your dogs are. there is no mental telepathy for anyone to know what your particular dogs are like.
