Reply To: Dog gets aggressive with other dogs when startled of fast movement

That sounds like she is doing a lot better… you may be right that she just needed time to settle in and bond with you  all. If she 18mth old it could have also been just a stage she was going through – the second fear period  generally occurs between the age of 6-14mths old. I think with your guidance she is going to be fine.
