My 6 and 7 year old nephews were over and in the basement playing with nerf guns. One year old Hitch seemed unconcerned until they came upstairs carrying their "guns". Hitch, fast as a speeding bullet ran over and stood about 5 ft from the kids and gave one loud bark. I told them to drop the guns and then Hitch sniffed them and lay down. He didn't make any physical contact with them but was definitely bothered by the weapons. He seemed almost to recognize them as something bad. The kids went downstairs again but every time Hitch heard the triggers he barked. Should I have been worried about the kids.
