Dog to Dog aggressive 6 month old Cockapoo
My dog loves any person she comes into contact with. She also plays very very well with dogs that she knows. When we meet new dogs, she either immediately growls and gets aggressive, or she plays with them for awhile and may turn aggressive after she becomes agitated by them. I fear introducing her to new dogs because her aggressive behavior is scary; its loud, seemingly violent, and scares other dog owners too.
What can I do? I really don't know when the behavior will occur because it only happens with some dogs, not all.
