Is it okay to admit I'm going to take someone's puppy while they're at work.
This is making my jaw drop, surely you are not serious! Why would you take someone's puppy when they're away from home?
I love it so much, I want to have it for myself.
If you take it form them without them knowing that's stealing and totally wrong. Get yourself your own puppy if you want one that badly.
What's the big deal? I'm going to make sure that it's taken care of.
You have to know that the owner will be very sad, and want to look for the puppy. Then if they find it you will be charged with stealing and go to jail so it is quite an ordeal in that way. A puppy is not something that is ok to be stolen no matter what you're intentions are.
