What an awesome photo! Flickr member 'Doubletee' has some great images, check 'em out. This is his text for this great little photo:
"A boy and his dog" - Van Nuys, California, 1969 - Well, on select weekends he was my dog. Bootsie (note the white fur on his front paws) belonged to my grandparents. (He had a cousin, Tinker, not pictured.) This is in the parking lot of my dad's auto mechanic shop (let me tell you, having a mechanic for a father in L.A. is golden); that's the home of Grandma & Grandpa on the northern part of the lot. Note that it's not the puppy on a leash here; it's the car. Bootsie lived a long life, dying in 1983 at age fourteen.
