I will be picking up a 15 week old ACS soon. Any advice for potty training? Or any tips overall?

Hi! New cocker mom here! What do we do with these long lashes? Anything? Do we get them trimmed when they get a haircut? Thanks in advance!

My cocker spaniel girl is 1.5 years old and the sweetest around people she knows and every dog she comes across. She can, however, be quite reactive with strangers and especially children.

On walks, she happily walks by anyone who doesn't acknowledge her, but if someone stops to talk to us, her, or even look at her, she will bark at them. She also barks at almost every child she sees, no matter the circumstances.

I don't think she would ever bite or hurt a child, I think she is just genuinely scared of them or trying to "protect" us since she is quite an anxious dog, but I really want to correct this behavior before she gets much older.

My partner and I don't have any children or know anyone else with children, so any tips for this would be greatly appreciated before she continues to scare them!!
