I just posted in Chi Chat about this...Poppy hs become very aggressive towards new people coming to the house..she hasnt met another dog yet, goodness knows what thats going to do to her!!Savaaha said:Is it commom for Chihs to be dog aggressive? Im noticing Sunny becoming more so in the last couple of weeks. I think its becouse hes grown more attached to and more protective to the family. He will even growl at dogs on TV. Any suggestions?
