My father in law once hit my dog. It was the first and last time he did it.
I came down stairs in the morning and the dog was cowering under the kitchen table and shaking, I rushed over and hugged him and said god what’s wrong with the dog, I was so confused, and my father in law said “ I hit him” just like that, he just said it, I hit him.
I was so utterly shocked to my core, I just stayed there kneeling on the floor holding my dog and said to him “you don’t ever ever hit my dog, you never ever hit my dog again” in both utter utter shock and total disgust.
As I was kneeling there, ,my husband came into the kitchen and I said, in front of his dad “ your dad hit our dog” . He was equally shocked,. We both just stared at him. My brother in law and his wife then came down, and I said to them, again In front of fil, he hit the dog. Again we all just looked at him aghast.
The dog was an abused rescue who we had spent a lot of time making sure he felt safe round humans, and everyone knew it, so to hit and hurt the dog was doubly cruel. And that’s why we were all so appalled. And the dog was terrified, shaking and hiding,
Tell her it’s not ok, or fuck her off for ever.
