Milo Murphy's Law Wiki

He's the greatest dog in the world!

— Milo Murphy, "Family Vacation"

Diogee Ex Machina Murphy is Milo's loyal pet dog. He is voiced by Dee Bradley Baker.


Diogee is a small, loving, devoted dog who is very loyal to his owner Milo Murphy. So much so that he manages to gets out of the house just to reunite with Milo at random times of the day, usually during Milo's predicaments. Diogee often casually appears to save Milo and his friends from any situation; this is used as a running gag in many episodes. Milo usually tells him to go home, and sometimes says "He's not supposed to be..." which can be said in any place where Milo usually is. He always knows the way home and the way to Milo. He doesn't always appear to save Milo, but he sometimes appears just because he wants to stay with him, even though this means disobeying his owner.

He likes the film The Dog Door Bone Files. He is very friendly with people like most well-socialized dogs.

Diogee has a lot of stamina. He's able to run to Milo's location and has no signs of exhaustion.

Diogee also appears to be smarter than regular dogs. He was able to read a map with directions to get to an airport, use public transportation, ride an airplane and use a parachute to get to Milo, apparently without humans thinking his activities odd or even interesting.

Physical Appearance[]

Diogee has cream-colored fur with small brown spots right over his mouth and a large, round, brown nose, floppy ears, and two brown "stains" over his back. He is also incredibly adorable.


Early life[]

TIoLD (91)

He has been with the Murphy family since Milo was a toddler. When Sara tried to teach Milo how to tie his shoes, Diogee began playing with the laces and inadvertently got tangled up with Milo when the attempt to tie his shoes failed. During this time, he was so adorable I feel like I could explode.

Further adventures[]

In "Fungus Among Us", Milo asks Diogee to stay with him instead of sending him home.

In "The Phineas and Ferb Effect", Diogee is with Milo, Orton, Cavendish, and Dakota when they meet Doofenshmirtz, who attempts to make conversation with him. Diogee then leaves with Milo and Perry to help retrieve a clock from his house and later reappears alongside Perry to help fight against the Pistachions.

In "Snow Way Out", he was sent home by Milo near the beginning of the episode but later showed up on a ship, where he helped them figure out an escape.

In "Agee Ientee Diogee", it is revealed that Diogee was once accidentally sent on an O.W.C.A. mission against Doofenshmirtz, and had successfully thwarted him.

In "Game Night", Diogee indicated that he wanted to join them in playing their board game and then participated all the way through. According to Dakota, Diogee won but cheated. Diogee responds to the accusation by growling.

In "Cake 'Splosion!", Diogee causes Milo and Amanda to fall during the last seconds of the contest. He whines and nuzzles up to Milo to beg forgiveness. Milo assures him it wasn't his fault.

Fungus (619)

Diogee is Milo's pet dog. Diogee leaves the house to find Milo on a regular basis and shows occasional disappointment when being sent home. He's constantly doing his best to help Milo out of trouble, often following him on risky adventures and appearing out of nowhere to save him in the nick of time.

Melissa Chase and Zack Underwood[]

Diogee is close to Milo's best friends. They took care of him when the Murphy's went on vacation, and he guarded the eggs for them while they worked on their science project. When Zack and Melissa were being followed by Agents Brick and Savannah, he helped slow them down so that the duo could escape.

Heinz Doofenshmirtz[]

Diogee and Doof got along in the beginning. Diogee was pretty happy to see Doof because he had a history with him once during the summer. He and Doof are on good terms.

Perry the Platypus[]

During the Pistachion invasion, Diogee began working with Perry immediately. He ran away with the clock Perry had entrusted to him so that the platypus could fend off the Pistachions, and later the two of them worked together during the battle, protecting their owners and fighting against the Pistachion army.

After Diogee accidentally got on the mission with Agent P, he licked Perry.

Season One[]

Season Two[]


  • His name's pronunciation is phonetically based off of the spelling of the word "dog".
  • It's possible that he only listens to Milo when being told to go home because in "Missing Milo", he did not go home even though Sara told him.
  • Dee Bradley Baker, who provides sound effects for Diogee, also did vocal effects on Phineas and Ferb, most notably performing the part of Perry the Platypus.
    • His role in the show also mirrors Perry's a bit, though their personalities are the opposite. Perry is a secret agent with human-level thinking, while Diogee is a relatively normal pet with normal dog behavior. While Perry usually hid from Phineas and Ferb when fighting against Dr. Doofenshmirtz, Diogee usually joins Milo to help him out of his difficulties.
  • In "Missing Milo", Diogee's full name is revealed to be "Diogee Ex Machina Murphy".
    • Coincidentally, the first three letters of his name "Dio" (as in "D-i-o-g-e-e") are forming an Italian word and came from the Latin "deus".
    • Diogee's middle name, Ex Machina, maybe a play on the term Deus Ex Machina, as he often appears randomly at just the right time to solve an otherwise unsolvable problem.
  • Milo and Sara call him "the best dog in the world", which is printed on his food bowl in Chinese.
  • Diogee is one quarter llama dog (mentioned in "The Llama Incident")
  • He can understand some commands in Spanish due to attending one of Milo's Spanish classes.
  • He has been given three other names, such as "Nigel Weatherbone" (by Doof), "Rex 2" (by Fuller and Hastings) and "Doggie Dog" (also by Doof).
  • He bears resemblance to Paw Pooch from Krypto The Superdog.
  • Diogee has his name in one episode title which is "Agee Ientee Diogee".
