I know my son is scared of fierce dogs, so I'm going to get him a Rottweiler.
Why, when you know that he is going to be terrified?
I don't care if he's terrified. I mean it's his own fault for being afraid of dogs
You shouldn't get the Rottweiler and force your son to live in a constant state of terror. That's not being a responsible and loving parent. Talk to him about what kind of pet he would like to get instead.
I'm going to enjoy this.
Why not be supportive of your son? Maybe you should get him a dog that is a little smaller so that he is not as scared.
