Hi i have a 24 week old female puppy, she is a black lab and husky mix. My question is she is already very aggressive, not to family but to people and animals she doesn't know. She is scheduled to get fixed the 21st and my worry is that it will make her more aggressive. If anyone has any input i would appreciate it. I have talked to the vet and she thinks it will calm her down i just want to make sure before we do it and it cant be undone.
