New behavior for my Lola, 2 years and 7 mths. And it just depends -- When we/she see other dogs she may do nothing/barks at them as she approaches and a few times sounds mean. If I can give her a minute then she calms down and then want to play. Not sure what to do about the barking and don't want the mean barking incidents to happen again? She has been to the vet and checks out? She is a lover, friendly - loves people, in fact people are drawn to her. She Interacts with my cousins 4 dogs and has sleepovers with my aunts who has a chi and a cat and they all get along famously, what am I missing?
