Years ago, we had a yorkie we rescued. He had all sorts of problems - separation issues, he was scared of his own shadow, but we loved him dearly. During a t-storm he dashed out the sliding glass door as the trash was being taken out - no worries - we had a fence. But in his terror, he climbed the fence (he'd never done that before) and was gone before the sliding glass door was closed and chase to catch him began. It was that fast. We searched for hours in the dark and rain and couldn't find Buddy. We hung signs, we checked the HS daily - no sign of Buddy. The next week at our son's little league game, the coach's wife was talking about a yorkie they found dead in the gutter in front of their home. It was our Buddy - not 3 blocks away. They'd buried him in their backyard. Thankfully Buddy was cared for in the end. But, dogs do get out, get away and get killed even when they have the lovingest of homes. Buddy had never been loose before. If it'd been 3 blocks in the other direction, he'd have been on 301. Dogs get loose and go wherever they go.
