 One weekend, 17 people killed and 100 shot. Yeah, and if you're a pet owner, chances are your pet's not been quite the same since last week with all the fireworks going off. And unfortunately for some, they're missing their pets now. The Humane Society says start with a neighborhood search and tell everyone you meet you're searching for a lost dog or cat. You're also going to want to hang large lost pet posters. Call your local animal shelter and ask them to keep an eye out.
