Missing light brown female Chihuahua (cimarron and wooldridge)

Our Chihuahua Heaven is missing, she was last seen july 30. It wasn't long before noticing she wasn't there but could not find her after going out looking. She knows the neighborhood and always returns home after a little stroll but this time she completely vanished which leads us to believe someone may have picked her up. We just want her back with her family, she is very old and not used to being away from her family this long. We are willing to give $300 for her return. Also if anyone has cameras in the cimarron and wooldridge neighborhood next to Jalisco's please check to see if maybe she comes up to help narrow our search if she wasn't picked up
