Making Petey your friend is super simple.  Throw him a ball!  Preferably one that squeaks.  Petey will keep his eye on the ball no matter whether it rolls on the ground, sails through the air, or bounces off the roof.  Once he has it, Petey will run back to you to show how talented he is to have trapped the toy.

After enough chases to get a bit tired, Petey likes lots of pets.  He does a full body wiggle to make sure every inch of his head, sides and back are covered.  All the while, Petey never drops the ball!
