Aggression or fear? Given the comments it sounded isolated, kid rolls up in it's face, it's not used to it because the owners haven't introduced the child properly, well let's shoot it? Because it reacted out of fear and all of the parties involved don't know any better?
The dog didn't react out of fear. It was introduced properly but decided to be aggressive. Thanks for jumping to conclusions and calling my grandpa, essentially, an idiot.
