My son went to spend the night with his friend last night and today when he was brought home him, his friend, friends little brother and mom came inside. Duece started barking, hair raised up on neck, and he peed all over the place and would not go near the kids including my son. Even after everyone else left he still kept barking at my son and would not go near him and when my son went up to him he ran from him and peed again. It took a while for him to warm back up to my son. What in the world do think made him react that way? The kids that came over were new to Duece but kids in general are not and they didnt come raising heck inside or anything like that and neither did they crowd around Duece. They pretty much ignored him and went straight in the bedroom. They only stayed maybe 5 minutes and I could not get him to stop barking that entire time. Duece is 17 wks and we have had him 9 of those weeks and him and my son have always been the best of playmates. Anyone have any ideas why he reacted this way? Especialy towords my son. Thanks!
