Are you serious, you really think that someone would break in to rob you and hurt your dog. Do you think that things is like an everyday thing in NY, were you planning on getting you apt broking into. Why would you want to move to NY if you think that your so likely to be robbed. That would be the last thing i would worry about with the dog in the city. You really can tell your a kid.
If you are afraid of New York City perhaps you should not live there. It sounds as if your family cannot afford to live there. Everyone in Manhattan has dogs or cats and they live in the apartment with them. No one is going to steal her. Your fears are really too intense and it isnt that bad. Make sure she has a coat in the cold weather because Yorkies are tiny and shake in the cold weather. Don t worry. She will be fine inside your apartment when you are at school. I had 2 or 3 dogs in a small apartment and it was fine. I lived on the Upper West side near Central Park. There is a dog park where she can be off-leash. Otherwise, there is a leash law on the streets and you have to pick up the poop.
