One of the best uses of social media by far are the various Facebook pages dedicated to finding lost pets. My neighborhood is a busy one, with large streets packed with cars, buses, and trucks, but is also family-oriented and many people try to look out for each other. When a dog gets lost, many times, s/he is found soon after by a caring neighbor who took the dog in the dog until the owner could be reached. I am always happy to see the owners reunited, but incidences of lost dogs happen too often, and it is the scariest thing that can happen to a dog owner. A few years ago, during a block yard sale, Django ran out of our house. She was just a puppy and she walked out a few feet in front of me. I calmly called her to come toward me, being very careful not to do anything that would make her bolt down the block, all the time my heart pounding. We live on a very busy street and I was terrified. She went to a tree and then came back to me. My heart continued to race for many minutes after that. Losing any of my pets has always been my biggest fear. Honestly, sometimes when Django was younger, I would put two collars on her during our walks.
Before that, our chihuahua Hayley snuck out of our yard under the fence and we could not find her anywhere. I called every rescue and vet, and then the police precinct. Finally, I was able to find her the next day at a precinct. The police were just going to take her to Animal Care and Control in a few hours when I found her!
