Im not sure if im doing this right , I just joined. My Labradoodle Daisy is 3 years old. All of a sudden she has become very possesive , maybe just very protective of her family. We will be walking her and she will start growling at everyone that goes by. This is really not like her at all. Shes really great with our other family dog, my grandkids. I dont get why she is starting to growl at people she doesnt know.
