Megan, I'm gonna share my story with you in hopes that it my give you so comfort, here goes.......in addition to my baby yorkie I have a 9 year old shih Tzu. One morning my husband opened the back door to let her out to go potty , when he opened the door there was a stray dog on the porch mooshoo (that's her name) took off to the races after the other dog my husband took off right behind them but that quick she was out of sight. We did everything you did to get her back. The bad part about this story is she didn't have identified tags on. We had moved and the tags we had weren't up to date. Seven long weeks went by , on the fourth of July my husband and my mother was outside preparing for a cookout a couple of kids was walking down the street with a dog. The dog barked my husband said " that sounds like mooshoo it was mooshoo she was home. We all cried on and off all day ,another thing we did that day was order her new pet tags and she now has a microchip. I learned my lesson.
so don't loose hope miracles do happen.
