Rosie is an anxious and excitable girl still at 11 months. She regularly barks the TV, at noises outside and when strangers come over, but I'm concerned that she also sometimes growls at adults (I think I mentioned in another thread, mainly with the one guy who has the grating, loud voice--and at us in a half-hearted way, only when we ask her to move when she is sleeping). And she has barked at children (but not growled at them). For example, the other day, she frightened some children because she went to the bottom of a tree that the children had climbed up and perched in, and barked up a storm. She has run toward children who enter a park where she can be let off leash, but not in an apparently aggressive way, more as if she wants to catch up with them and say hi, but this has frightened them. We want to address these behaviors, so that isn't the question, but I'm just wondering if this sounds abnormal for the breed. How concerned should we be?
