YUP; a dogs owner is ALWAYS RESPONSIBLE for that dogs behavior!
If this dumbass can’t properly socialize his dogs he should not have any animal under his control.
I have 4 Dogs, each big enough to kill a human with no help from the others.
If my dogs act up they will answer to me, they don’t want that to happen.
All 4 of my dogs are what is called “GURDIAN BREEDS”, that means PROTECT—NOT ATTACK!
If any of my dogs attacked a human being for any reason OTHER THAN THAT HUMAN SHOWED A CLEAR AND PRESENT DANGER TO MY FAMILY, I would put that dog down myself!
You sound just like my son. A responsible dog owner. Thank you for not saying dog daddy lol.
