Dan and Diesel

Dan’s dog, Diesel, is a wonder dog. He can do anything. He can ride on trains and planes and in underground tunnels. He can stand next to an enormous smoke-breathing dragon and never flinch an inch.
When Dan is with Diesel he can go anywhere. He can go shopping at the market. He can play jazz in the Boogaloo band. He can climb mountains and draw pictures in his head. Together, they can conquer the world!
But one day, Diesel is whisked away in a big black van . . .
Only when Dan and Diesel are finally re-united does it become apparent that Dan is blind and Diesel is his guide dog.
