In addition to thousands of rescue workers who have worked tirelessly at the bomb site, some hard-working dogs have been there too. One of them even died in the effort. The SPCA was on hand to wash off the dusty feet and noses of those hard-working canines, other groups have sent booties to protect their feet. Let us celebrate the folks who train with their dogs to help save lives or, as it looks today, provide answers to grieving family members.
