"If my dad were a dog,  just for one day,  I'd tell him to sit and I'd tell him to stay."   Woof!   What kid wouldn't relish the chance to put a leash on Dad,  bark out the commands for a change,  and then spend the entire day at play in the park?  With refreshingly direct, unfussy photos of a great big slobber-happy black Lab set against cheerful,  simple,  primary-colored backgrounds,  IF MY DAD WERE A DOG playfully explores,  in rhyming text, just what would happen if this,  every young child's wish,  came true.  "Good dog! Good dad!"
