We got our 10 month old rescue dog that has been with us 2 months now. She is great with us, a lovely dog in the house and great with other dogs. The problem is when visitors come, she is very aggressive. Barking incessantly and then biting, she bit the cleaning lady, she bit my husband's 2 aunts when we went to visit them and this weekend it escalated. My parents in law came to visit. It started as usually with excessive aggressive barking and then when my mother in law got up to go to the bathroom she followed her biting and her, when she came out of the bathroom she was bit and fell to the floor. The bite was superficial but there was a fair bit of blood. The dog then bit my father in law.
I worry the aggression is escalating as she is defending what she now feels is home.
The lady we got her from says she will take her back, my husband wants to keep her and see if we can work through her problems, seeing a behavioral specialist etc.
This is my first dog, I have no experience and honestly I'm ready to give her back. should I persevere? I would really appreciated your opinions.
She is medium size, crossed breed (we don't know what) she looks a bit like a mini golden retriever, to give you an idea
