When my dad told me that he was flying to San Francisco to pick up a dog, I was a little concerned. My parents often foster animals for their local humane society, and once again, their house was full. The last thing they needed was to pick up a dog to foster from out of state. I was really excited, though, when he explained what he was doing. He was volunteering for the Guide Dog Foundation, transporting the puppy from its breeding home to the handler that will prepare the pup for official training.
