it has been 13 days since my dog got lost..!what should i do?

Put up posters with your dog's photo and offer a large reward for her return. If she was stolen, the man might bring her back to get the money, and if he doesn't, likely one of his neighbors will. Ask your parents to also post her picture in your local newspaper so that lots of people know she's missing and there is a reward.

And spamming is against Yahoo rules. There is nothing we can do to find your dog and you've posted at least 14 times about this in the last week.

The dog is long gone since you made it clear you left the dog outside all the time and never once cared enough to keep the dog indoors, on a leash and let it run loose.

You failed to care about the dog, failed to go LOOK for the dog and have done nothing but post spam

You were told what to do when you originally posted this, if you haven't done so, then do it, at this point I'd say the dog is long gone, get over it, and don't get another if you can't supervise and contain it properly. Reported for spamming.

That is probably exactly what happened too. Put up some fliers but really? Get another dog. This one is gone.

Post flyers then.
