A rather imaginative story. Humans have research setup on the hard "surface" deep inside Jupiter! They live in domes. To move around, they must transform their physique to become suitable. A machine can take an earth animal & produce a Jovian life form, & vice versa!! But each time a human is sent to explore Jupiter in the open using this method, he vanishes! After several incidents, the man in charge decides to go himself with his dog. Of course, he will also desert; living the Jovian way is so much more interesting than living in a human or dog body!
