Sounds to me like you hurt his feelings when you said you wanted to rehome kizzy!
Men get very attached to these little dogs. Hopefully you will rethink rehomeing her and keep her and try to train her not to be so agressive instead of just giving up on her. I think she deserves that much effort, dont you??
Everything in life is not easy and especially raising dogs, but if you put effort into it, you will be suprised how things can change.
