I know she loves dogs so I'm going to take hers.
Why would you do that? Aren't you worried about getting caught for stealing a pet?
No one will ever know that I took her dog
You should never take someone's pet. Some people have strong bonds with them and if you take them away. It's like taking some part out of them.
What? It's not like I jumped over the garden fence and drag the dog into my car. Anyway, the dog is with me and I have evidence that I have it.
You should give the dog back, or else you're really going to hurt this person greatly. How would you feel if someone stole something from you that you love? Have a little compassion.
