Hi All, I haven't posted in here in awhile. But my yorkie is 3 years old. She has been raised around young children (not on a daily basis) but several times a year we have events at my house with little ones. Tonight she did not like them the loudness maybe, but she nipped at them and was just not happy. Why might this behavior occur, I am the pack leader and we have other dogs and she has never done this before. Any advice would be wonderful
