Rusty yips and tosses the chew toy in the air, and lets it fall between them. Alex can't help himself - he lunges forward and grabs the big rubber ring in his teeth at the same time Rusty grabs it.
The German Shepherd is a large dog, and Alex has to brace himself on hands and knees to hold against the animal's strength. He feels the toy slipping from between his flat teeth, and whines. It sounds very much like a dog's whine. Rusty's slobber is all over the chew toy, and it tastes funny for a minute or two. Alex finds that it is getting easier to hold onto the chew toy - his teeth are sharper, and his mouth feels bigger. It isn't until he can see his face pushing out into a muzzle that he lets go of the toy in shock.
A very doglike yip emerges from his mouth as he scrambled up to check himself in a mirror. He has the head of a German Shepherd!
