The polar opposite for the former is true in Real Life hounds are actually among the most energetic dogs out there. Alternatively, they are often used as the basis for Hellhounds due to similar-sounding names. Sometimes they are also portrayed as seemingly dumb Good Ol Boys, but are actually more intelligent than their lazy-looking, dopey appearances let on.

Larger hound breeds (such as basset hounds, coonhounds, or especially bloodhounds) are commonly depicted as sleepy, laid-back Mellow Fellows with large stomaches and are mostly associated with having a Southern accent.

Designer mixes in fiction are almost always part-poodle, likely a result of crossbreeds with said dogs being enormously popular.

If a designer mix isn't a labradoodle or a goldendoodle, it's a small Mister Muffykins Rich Bitch who lives with an equally vain owner.

Positive portrayals of hairless dog breeds can range from Bald of Awesome, Creepy Hairless Animal to Ugly Cute, though.

Hairless dog breeds are primarily susceptible to the dog version of Bald of Evil trope, since they don't come off as friendly as their fluffy counterparts.

Feral dogs are usually viewed in a Scavengers Are Scum light, especially if the setting is a post-apocalyptic world.

Chinese dog breeds like Pugs, Chow Chow, Pekingese, Shih-Tzu, Tibetan Mastiffs and Chinese Crested dogs were portrayed differently depending on situations they were used to represent the (very offensive) Yellow Peril stereotypes.

Akita, Jindo, and other large, Asian Spitz types are Angry Guard Dogs.
