An old dog, typically seen in a rural setting. It is frequently male, often will be some sort of hound, and usually splits its time between sleeping and barking. Sometimes known for having been a good tracker or hunter in the past.
In talking-animal fiction, the Old Dog may be portrayed as a grandfatherly character, or just as a crabby old guy.
On a more cynical note, old dogs are legendarily unable to learn new tricks. However, plenty of owners will dispute that and call it a wives' tale.
- Victor's dog Makkachin from Yuri!!! on Ice is quite old for a dog (judging from an In-Universe interview, he's at least 15 years old), but it's downplayed since despite liking to sleep a lot, he's very energetic and puppy-like when he's awake.
- Jeff the old dog from Kiki's Delivery Service is slow-moving and sleepy, but helps out Jiji the cat (who has disguised himself as a toy) by keeping him safe until Jiji's owner Kiki returns to get him.

- In stark contrast to the Disney example, Copper is the Old Dog in Daniel P. Mannix's The Fox and the Hound. In a rare Evil Old Folks version, this one comes across as a Villain Protagonist dog for some readers. Depends on how much a given reader can get into the mindset of a character that's intentionally written as having a very alien sense of morality since he's not human.
- Bodger the bull terrier from The Incredible Journey.
- In Discworld, Vetinari has an old greyish terrier named Wuffles, who smells like death and spends most of his time sleeping. When Wuffles eventually dies, Vetinari visits his grave regularly in an uncharacteristic show of sentiment.

She quickly adopts Buru-Buru and raises him to become a kindhearted young lion who acts like a dog. Due to the age gap between both species, by the time Buru-Buru becomes a fully grown lion, Muku-Muku becomes an elderly dog with wrinkles around her face, a noticeably skinnier body, and a relaxed and laid back personality.
- Andor: B2EMO may be a droid but he's clearly intended to evoke an elderly pet dog, per an interview with showrunner Tony Gilroy. He's very old, very loyal, and doesn't have much energy. His recharging station is even suggestive of a dog bed, and he can pull off Puppy-Dog Eyes with his large photoreceptor.
- The Beverly Hillbillies: Jed Clampett's bloodhound, Duke. Duke was already an old-timer when the show began, so he was extremely old nine years later. One can only presumes Granny's Spring Tonic helped extend Duke's life.

They just never told him that old dogs die and didn't want to dissillusion their son.

- Farnham Fables has Barnabas, the Edison family's elderly bloodhound. He can be found sleeping near the stables in episodes 2 and 3.
- Chop, Lamar's (though he mostly stays with Franklin) dog from Grand Theft Auto V, is seen significantly older in Grand Theft Auto Online. Back in his heyday (2013), he was Franklin's Canine Companion who was quick on his feet and could sniff out trouble, attacking on Franklin's command (sexual distractions notwithstanding). Years later, his fur has grayed and he doesn't get around to much anymore, as described by Franklin. There's even a Bait-and-Switch where it seems as though Chop is finally dying (going by a rottweiler's typical lifespan, by 2021, he should be on his last or second-to-last year), but he's actually just stoned off his ass eating one of Lamar's pot brownies.
- EarthBound Beginnings has Ninten's dog (and very first friend), Mick. According to "Encyclopedia MOTHER," Mick was one year and five months old when Ninten was born, making him thirteen to Ninten's twelve during the events of the game. When Ninten was a toddler, Mick would let him ride on his back.
- EarthBound (1994) has King, who belongs to Ness's family. A flashback shown late in the game shows that King was a puppy when Ness was born, making him about thirteen/fourteen years old during the events of the game. No wonder he spends most of his time sleeping around the house!
- King of the Hill:
- Subverted in an episode where Peggy gets a job working for the Alamo Beer Company and becomes privy to many of the company secrets. One of those secrets is that the supposedly old dog that appears in the Alamo Beer commercials is actually the third or fourth replacement and that the original dog died several years ago.
- Hank's dog, Ladybird, is a straight example. She's nine months older than Bobby, making her (in all likelihood) 14 years old when the show ends. Most bloodhounds live 6-8 years and seldom make it past 12.
- In Family Guy, there's Herbert's dog, whose hind legs don't work.
- In the very first episode of American Dad!, Stan gives in to Steve's requests for a pet dog and adopts Thor, who clocks in at a positively ancient 19. Stan meant well; he thought Thor was better for having lived through the Reagan years, but as you can imagine the poor thing died very quickly. Though to be fair, it might have lived a little longer if Stan hadn't shot it in the head.

A young pup comes along to show Rover up and make fun of how old he is, but comes to regret it when Rover risks his life to save Porky and the pup from some exploding dynamite. And in the short, Dog Tales, we meet "a Newfoundland . . . and his grandfather, an OLDfoundland."
- Wolf falls into this by season 3 of Young Justice, eight years after his discovery and adoption. Formerly an active companion and member of the Team, he's now most content to lay in the background and snooze.

- The Old Friends Senior Dog Sanctuary has become popular online because the dogs are especially cute because they're old.
- Older dogs are harder to adopt than younger dogs, so shelters are known to milk the "benefits" of adopting a senior over a puppy (their personalities are set in stone, most are already house-trained and know a few tricks, they won't grow, they're usually lazy, etc) when trying to market their adoptable seniors.
