My dog felt that someone screaming and running at the family with an object was a treat, yes. Dogs can not distinguish age. You are making a case on why you are being uneducated about the entire situation.
So my dog that has never bitten, or shown any real aggressive towards anyone ever warrants a muzzle? She is around people of all ages daily, including infants.
Maybe you are irresponsible dog owner because you did not socialize your dogs to behave in public, so instead of training it you just leave it at home.
But by all means please be done with this conversation. No one wants to hear your ability to discharge firearms at parks where guns are not allowed near children and other familys, Mr. Responsible
