"Grunt, Woaoink, I am bigger!" The now more pig than man Billy said looking at his altered body. "Where's my *grunt* peepee?" he said in his deep voice as his malformed hand touched his sheath.
Billy's father was still in shock when he heard a weird moaning coming from the other room.
Billy and his father both went toward the living room to see where the noise came from. There on the floor was the 7 year old family retriever Rex. His paws were holding his stomach as his shortening muzzle let out a moan that sounded like a dog and a boy at the same time.
As they watched, his front paws expanded into child size fingers and hands. Fur was quickly pulling into his body, each moan sounded more and more human. Knees snapped as legs straitened and feet partially formed. Rex's full grown balls began to shrink as his sheath detached partially, penis shrinking down to his new humanized age.
Rex began to stand, back cracking, his tail was now only a foot long. His body hair would now be considered thick for a grown man, but out of place on the 7 year old that was more human than dog now.
"Mu mu master?" the new boy said in his high voice.
