I'm going to hit my dad because he hit our family dog
Is he normally nice to the dog?
Yes, he plays with the dog in a very gentle way most of the time.
Even if your parent is hitting your pet you shouldn't hit them back. If you know that someone is abusing their animals you should report them to the police.
You think I should call the police on my father? That's crazy. I'm just going to smack him up side the head and tell him to leave the dog alone.
Are you sure that hitting your dad won't just cause more problems for you? I'd think that your father might try to hit you back. Can't you just talk to him about the dog instead of being violent with him?
