Overview
He was the one responsible for separating Courage from his parents as a puppy. He captured them, put them in a rocket ship launched from his so-called "animal hospital" named "Pets of Tomorrow", and sent them to space as part of his breeding experiment, to see that they would turn into superdogs. However, Courage escaped from this fate and was adopted by Muriel.

Years later, he tries to do the same to Courage after recognizing him from the past. When Muriel and Eustace attempt to rescue Courage, as well as discover his experiment, he decides that he can't allow his operation and research to be discovered and compromised to the public. He also explains his evil plan to Muriel and Eustace, who will become "the first humans to see his secret experiment at work", which he argues that "breeding dogs in space is the future". Therefore he decides to throw Muriel and Eustace into the rocket to be sent into space as well.

However, Courage rescues his owners and locks the Cruel Veterinarian inside the rocket. After T-0, the rocket engines under it ignite and the rocket launches sending the vet into space instead. Crash landing on a planet, he finds that all the dogs have survived, including Courage's parents, which meant that his breeding experiment to see that they would turn into superdogs had failed. He is then petrified, as he is dragged off in a net and attacked by the vengeful dogs off-screen for his actions. He is heard screaming in pain during the attack.
