What do You do if Your Pets Run Away?

I frequent a group page for the Philippine Animal Welfare Society (PAWS) in a certain social media website and every now and then I would see posts of missing dogs. Most of them are Shih Tzus and because my own dog is the same breed, I cannot help but be sad about it. This is why I'm very careful to not let the doors and gates open. All of us here at home are very particular about house security especially after being robbed twice. Also after reading the news about abducted dogs being used as bait for illegal pitbull fighting rings, I would not risk my dog being kidnapped.
