Me again sorry

[labellesusage]

So dog spayed earlier this week. All going fine. Wound healing beautifully. Lead exercise going well. Doing what dogs do. But.
Is it hormones?
She is now lunging at other dogs and barking at them?
Never had that problem before (except black small dogs?)
Will she be ok or will she be like this forever?

It takes about 14 days for dogs to recover after neutering. Maybe she is warning them to stay away as she is still recovering.
