Out of gas / Hayes, Vicki C

"Trey really wants to play soccer. Mr. Dean really wants him to come up with a science project. But Trey can't think of anything. Maybe he will find inspiration in the woods, so he takes his dog for a walk. All of sudden there is a tremendous thud. An alien spaceship has crashed. Trey cannot believe it when two blobs roll off the ship and morph into exact copies of his dog!" -- Amazon.

When Trey takes his dog for a walk, he discovers that an alien spaceship has crashed and the aliens take the shape of his dog.
