Villain Overview

May I talk with the two of you for a moment? ...In private?'
~ The Cruel Veterinarian's infamous quote.
You've seen too much! You'll be the first humans to see my secret experiment at work. Breeding dogs in space IS THE FUTURE!
~ The Cruel Veterinarian deciding that he cannot allow his operation and research to be discovered and exposed to the public, revealing his true nature and his insane "secret experiment" to Muriel and Eustace, who attempt to rescue Courage from suffering the same fate as his parents, before throwing and locking them in his Rocket.

The Cruel Veterinarian is a sadistic animal doctor and the overarching antagonist of Courage the Cowardly Dog, serving as the main antagonist of the episode "Remembrance of Courage Past".

This unusual doctor, who runs his Pets of Tomorrow veterinary hospital, was the man who is responsible for taking away Courage's parents and launching them into space when he was an infant for an experiment (which later failed) and making the latter an orphan, until he was adopted by the kind Muriel Bagge. He is considered to be the first enemy that Courage faces in his life.

He was voiced by Jim Cummings.


He is elderly and monstrous in appearance, wearing an ordinary lab coat with a stethoscope attached, and wearing boots. He is bald and also has a scary beard and mustache, some eyeglasses, scary eyebrows, scary nose and ears, and monstrous crooked teeth.


The Veterinarian acts like a kind old man, as evidenced by giving an infant Courage some candy and talking to his parents in a kind voice. However, this was only to conceal his true nature: in reality he is a sadistic, sinister, cruel, cold, antisocial and greedy mad scientist and schemer, believing that sending dogs into outer space would breed space dogs.

Using his secret knowledge of rocket science and aerospace engineering (and based on 2 posters he saw), this has led him to send many dogs into space against their will. He will also send people to this same fate, to avoid his research being exposed and compromised to the public, also completely uncaring about human life or their well-being, as evidenced when he caught Muriel and Eustace with a net and then (using the same net) throwing them into his rocket and locking the rocket's door to prevent both Muriel and Eustace from escaping. He is also manipulative, as evidenced when he persuades Courage's parents into talking with him alone, only to get nabbed by him with a net.

He is extremely fearful, as evidenced after he ironically suffers the same fate as his victims, he was petrified as the dogs that he sent away were extremely angry at him for his actions, resulting in the dogs attacking him off-screen.


The Veterinarian was the one who was responsible for separating Courage from his parents as a puppy. He manipulated Courage's parents into talking with them alone, which was revealed to be a trick as he captured them. Courage followed the evil veterinarian to his secret lab as it was revealed that he was shoving and locking them in a rocket. This was as part of his secret breeding experiment, to see that normal dogs (in space) would breed space dogs. However, Courage attempted to save his parents, but is spotted by the vet, who then chases Courage around the lab. Courage eventually uses a garbage chute to escape the evil veterinarian, and watches as his parents were sent to space. He was later adopted by Muriel.

Years later, Muriel and Eustace Bagge took Courage (still traumatized by the events) to the same vet that kidnapped and launched his parents, after recognizing him from the past, talking to them about speaking to him alone, which was secretly just a façade as he tries to do the same actions that he did to his parents earlier to Courage. Fearing that the Cruel Veterinarian would send him to space, Courage runs away and is chased in the hospital, running to open the door to his secret lab, but as he tries to open the rocket control room door, the Cruel Veterinarian nabs him with a net as he takes him to the same rocket ship that launched the latter into space, starting the same countdown before, and then throwing him inside and closing and locking the rocket's door.

When Muriel and Eustace discover his breeding experiment, as well as attempt to rescue Courage, he decides that Muriel and Eustace have seen too much, and that he cannot allow his operation and research to be discovered and exposed to the public. He catches Muriel and Eustace with a net, and briefly explains that they will become the first humans to see [his] secret experiment at work,and claiming that breeding dogs in space is the future of normal dog breeding (with Courage opposing the crazed vet's evil space breeding scheme), before throwing them into the rocket and locking the door to be sent into space to prevent them from interfering with his cruel plan.

However, while he closes and locks the rocket's door, Courage escapes and is chased around the lab. Courage knocks over a bucket of bolts and screws, causing the evil vet to slip. 30 seconds to launch, Courage tries to open the door to the rocket to save Muriel and Eustace, but to no avail. As the Cruel Veterinarian confronts Courage and nabs him again, trying to throw and trap him in his rocket again, this backfires when Courage screams into the stethoscope, almost deafening the Cruel Veterinarian, and causing him to scream from the pain.

While he is screaming, already distracted from Courage's screaming, Courage then snatches the Cruel Veterinarian's rocket door key from his pocket, unlocks the door and releases and rescues Muriel and Eustace while the Cruel Veterinarian takes off his stethoscope, throwing them to a nearby bin. 8 seconds to launch, the Cruel Veterinarian tries to nab Courage to throw and trap him in his rocket yet again, but this also backfires as Courage bangs the rocket's door causing him to become weak in the process, weakly laughing as Courage traps the Cruel Veterinarian inside the rocket.

About 5 seconds to launch, Courage runs to be comforted by his owners and away from the rocket. As it reaches 0 seconds, the rocket engines under it ignite and the rocket launches sending the evil vet into space instead. At the end of the episode, this same rocket had already crash landed on an unnamed planet, as the evil vet opens the rocket's door and is then petrified, finding out that all the dogs (including Courage's parents, and the same dogs seen on the milk carton's "Missing" advertisement at the beginning of the episode) have survived the trip in space, and didn't breed any space dogs as he hoped, which meant that his breeding experiment to see that normal dogs would breed space dogs has failed. Out of pure anger by the dogs, the Cruel Veterinarian laughs nervously onscreen for the last time before he is dragged off in a net and mauled by the vengeful dogs off-screen for his actions. He is heard screaming in pain during the attack.

It is completely unknown if the Cruel Veterinarian survived or not, but even if he did so, he most likely remained on the planet until he starved to death or is still stranded there with the dogs.


  • The fact that the Cruel Veterinarian was the first enemy Courage ever faced in his whole life in spite of being an ordinary human is very fitting, as this may reflect that something with a monstrous appearance is never always evil and that some humans can be wicked and depraved.
  • In some ways, the Cruel Veterinarian can be considered the Greater-Scope Villain of Courage the Cowardly Dog: if he had not sent Courage's parents to a planet, Muriel could have possibly never found an orphaned Courage.
  • He is presumably based on animal testing during the Cold War and the Space Race between the United States and the Soviet Union (e.g Laika).
