Howling at the Moons

In a corner of the galaxy far far away, Dr. Cy Berger, operating the first interplanetary veterinary service, lands on Lupus IV where he and his crew are tasked with reversing a DNA defect that prevents young werewolves from shape-shifting like their parents. Since this problem was due to Cy's previous attempt to save the Lupan society from genetic extinction, he must shoulder the blame. If he fails to correct the defective gene in the offspring, the sentient race will turn feral, and he will be dog food.
