Last night, my (23M) fiance (20F) was bit by her dad's dog. We were sitting in the living room, and she noticed the dog (named Parker, a very small dachshund/ jack Russel no more than 20 pounds) had a squeaker from one of his toys in his mouth. My fiance got up real fast and ran over to Parker to try and get the squeaker out of his mouth since it was very possible Parker could choke on it because of how small he is and the squeaker is. Parker started growling and backing away from my fiance, and while trying to get the squeaker out of Parker's mouth, he bit her. She started crying, kicked the dog away from her, and ran to the bathroom. I followed her. I comforted her while she cleaned the wound in the sink. She was bleeding on both sides of her finger and it was swelling pretty bad. She kept saying she was going to "kill that dog." I said "I understand your hurt and upset, but Parker is animal. He was acting on instinct. He felt threatened." My fiance said "I don't care. I was trying to make him not choke, and he bit me. Maybe next time I'll let him choke."

I got her some ice to put on her finger, and she walked back into the living room. Her dad asked to see her finger, so she walked over to him and got pretty close to show him her finger. Parker was at the foot of the chair where my fiance's dad was sitting, and as my fiance moved her hand closer to her father so he could see it, Parker got defensive and tried biting her again, nipping her ankle. My fiance screamed at the dog "I HATE YOU", kicked him again (pretty hard this time), and ran to the kitchen. She was crying and hurt. I sat there with her until she stopped crying and made sure she was okay. She kept repeating how she hated Parker and how she thinks he's only ever been a problem since her parents adopted him (which is kinda true, but I'll spare that story for a later time). She kept saying she wanted to kill him and how she was only trying to keep him from choking. I told her that I understood that, but Parker doesn't. He's an animal that acts on instinct. He can't control his actions, but you can.

Later on, she came to me and said she was upset. I asked her if it was still because of being bitten. She said "No. I'm upset with you because I feel like you're defending the dog over me." I told her that I kinda was. I said I didn't like that she kicked him multiple times and kept threatening to kill him. I don't think she'd actually kill him, but it was concerning to me that her first reaction to being bitten was to kick him and it was really hard too. In my eyes, that's abuse. I told her it made me think about how she may treat our children one day if they upset her. Is she going to lash out and hit/ kick them when they upset her? And she said "well that's what happened to me when I was a kid." I told her "yea, I was abused too and I'm not laying a finger on my child ever. There are better ways to discipline than physical harm." She shrugged her shoulders and stormed off.

I came to bed about an hour later and was trying to talk to her but she was ignoring me. I tried saying goodnight and I love you, but she said I don't love her because I was defending the dog over her. I said that I do love her, I just didn't like her actions. I brushed it off, and we fell asleep. She woke up for work this morning and she woke me up to give me a hug and a kiss before leaving. I said "I love you. Have a good day." And she said "I don't feel loved because of last night." And went upstairs to leave for work without another word. She's really upset but this, so I just wanted to know if I'm being an asshole to her in this situation.
