- Awesome Music: The theme song.
- In a weird way, the Nutrition song.
- Ear Worm:
Kick off our shoes and our socks,'Cause you know that Belgium ROCKS!
- Boy is the theme music catchy.
- As is T.D.'s Belgium song.note
- Esoteric Happy Ending: The ending of Dog Daze has Carolina turned into a dog. The episode plays out without her turning back to a human. The next episode has her back.
- The episode actually ends with Truman pointing this out, so the episode resumes by having all that to have been a dream.
- Family-Unfriendly Aesop: "Martha Calling:" Martha wins a country club vacation in a phone contest. The thing is, dogs aren't allowed. Rather than leave Martha at home, they disguise her as their wheelchair-ridden grandmother and sneak her in. Not only is this dishonest, it's also illegal. But nobody cares when the truth is revealed. In fact, the owner actually starts allowing pets after Martha is exposed. It's not that bad and this is a children's series after all, but it's still an example.
- Hilarious in Hindsight: From "Dogs in Space":
Helen: "Dad, we found your favorite comic."Dad: "Pinkie the Pony?"
Truman: Have you ever heard of an alien settler in a Western?
- In "Martha Out West", TD wants to put aliens in his home-made Western movie.
- Nightmare Fuel: Martha's nightmare in "Too Much Martha" portrays her as being literally paper thin and unable to really move on her own, yet still forced on a (stricter) diet by Helen to "lose weight". While the sequence has some admittedly amusing moments, such as paper-thin Martha being flown like a kite for a "walk", Martha's panicky And I Must Scream state and Helen's obliviousness (or indifference) to Martha's condition make it all the creepier.
- The episode "The Trouble With Teddy" has some scary moments, including one of the dogs who was implied to have had a near-death experience in the past.
- For anyone who is scared of the idea of sleep deprivation, Martha being tired in "Martha's Chair" and her and Helen being tired in "Martha Walks the Dog" can be scary.
- Though "Camp Truman" mainly averts this, several of the suggested ideas (like Milo losing his ability to ever be happy and Milo getting tired) were pretty creepy.
- Another nightmare of Martha's in "Fit vs Fat" is a bit of this, because, in it, her, Helen, Alice, T.D., Truman, and Ronald are very lazy. In fact, the kids (sans Ronald, who is slightly less lazy) are so lazy that they have great trouble lifting small objects and groan all the time.
- In "Helen's All Thumbs", the negative effects of Helen's gaming. Particularly her forgetting to feed Martha and Skits and especially her hallucinating sprites from the game!
- Periphery Demographic/Just Here for Godzilla: A sizable portion of teens and adults enjoy it for how surprisingly clever the writing is and the shared cast/crew members with My Little Pony: Friendship Is Magic.
- Ridiculously Cute Critter: Several!
- Martha and Skits as puppies. Heck, they're cute as adult dogs!
- Mandarin, Streak, and Butterscotch.
- Prof. Monkey.
- Even Nelson.
- Squick: Martha eating and rolling around in garbage. Also, in one episode she claimed to be rolling around in dead snakes.
- Nelson throwing up in "Martha Takes the Cake"
- Martha asking if she can pee on the statues, and both dogs peeing on the rug as puppies.
- When it's implied that Teddy once ate Jake's diaper and when Butterscotch throws up in the Flash Back. Both happen in "The Trouble With Teddy". Also implied that T.D. ate bugs as a toddler.
- Viewers and characters alike can agree that this conversation from "Truman and the Deep Blue Sea" qualifies as this.
Martha: "Guys, you'll never believe what I found. Free hot dog buns. There were tons of them in that can over there."Helen: "Martha, that can is a garbage can!"Truman: "Okay, that's enough info!"Martha: "Oh, that's why there were little bits of hot dog in there as well."Truman: "I feel queasy".Martha: "And something a little eggy."Truman: "Make her stop!"
- Ronald eating too many cookies in "The Thousand Fleas". Making "ooh" noises, telling Alice not to say the word "cookies", all that jazz.
- The fact that Martha and a little boy hated the burgers at Big Burgertorium, despite the word "yum" being in its jingle, also gives it a surreal, eerie vibe.
- The Woobie: Martha is usually happy, but when she has to suffer, you can't help but feel sorry for her. Such episodes include "Martha Changes Her Luck", when she thinks she's cursed with bad luck that's rubbing onto others.
- Teddy in the episode "The Trouble With Teddy".
- Skits in the episode "Martha and Skits", thankfully he is not usually a Woobie.
- Helen, though not usually a Woobie, is sometimes one in a few episodes, notably "Martha's Got Talent" (her stage fright), "Helen's All Thumbs" (calling herself the worst owner, not being able to go to the museum) and "Martha in Charge" (she was the unfortunate undergoer of a Sick Episode).
Skits: *whines*Martha: "Come on, Skits, that's silly! Helen does not love that game more than us!"Skits: *whines again*Martha: "She has not forgotten about us. You'll see. She's bringing us a picture of a bone from the museum"
- Martha and Skits are also Woobies during "Helen's All Thumbs" due to Helen forgetting to feed them, and this conversation between Martha and Skits.
- Truman can be this in "Truman and the Deep Blue Sea".
- Milo can be this in "Milo's Reading Buddy" and "Skits & Mr Scruffles"
- Butterscotch in "Nurse Martha"
- Alice in the episode "Alice Twinkle Toes"
- Martha and Danny when they're trying to give up digging and snacking respectively in "Martha's Dirty Habit". Danny is seen reaching for food but then sighing and putting it back, and Martha is seen staring out the window moping.
