Small dogs are often seen as adorable lap companions, but don’t let their size fool you—some have big personalities and strong opinions, especially when it comes to other dogs. While not all small breeds are antisocial, certain ones have a reputation for being less-than-friendly toward their canine peers. Here are 10 little dogs that often prefer people—or solitude—over other pups.
Chihuahua
Chihuahuas may be tiny, but they come with a bold, feisty attitude. They tend to form strong bonds with their owners but can be territorial and standoffish with unfamiliar dogs. Their big-dog complex can lead them to challenge much larger dogs, often to their own detriment.
Dachshund
Originally bred to hunt badgers, Dachshunds are brave and tenacious. While they’re loving with their families, they can be aggressive toward strange dogs, especially those who invade their space. Early socialization is key, but many still prefer to be the only canine in the house.
Pekingese
These regal little dogs were once favored by Chinese royalty, and they still carry themselves with a certain aloof dignity. Pekingese can be stubborn and protective, and they don’t usually enjoy the company of other dogs, particularly those with high energy.
Jack Russell Terrier
High energy and a strong prey drive make Jack Russells a handful. They’re smart and loyal but can be very reactive, especially toward dogs they perceive as competition or threats. They do best as the solo star of the show.
Lhasa Apso
Bred to be alert watchdogs in Tibetan monasteries, Lhasa Apsos are naturally wary of strangers—dog or human. Their independent nature makes them selective with other pets, and they can be snappy if they feel crowded or threatened.
Miniature Pinscher
Don’t be fooled by the Min Pin’s toy size—they are confident, proud, and often aggressive toward other dogs. Known as the “King of Toys,” this breed likes to rule the roost and isn’t afraid to let others know it. Their bold personality and fearless attitude make them seem much larger than they actually are.
Shih Tzu
Shih Tzus are sweet with people, but they can be possessive of their space and toys. While not always aggressive, many Shih Tzus simply prefer to be left alone by other dogs and may snap if their boundaries are crossed.
Toy Poodle
Toy poodles are intelligent and sensitive, which can make them anxious or reactive around other dogs, especially if they haven’t been properly socialized. They often do better in calm, predictable environments without a pack.
Yorkshire Terrier
Yorkies are known for their bravery and loyalty—but also for their bossy streak. They may become territorial and barky around unfamiliar dogs. Some Yorkshire Terriers prefer the company of humans to that of their fellow pups.
Brussels Griffon
This expressive breed bonds closely with its humans but can be shy or defensive around other dogs. They’re not always aggressive, but their tendency to be clingy can lead to jealousy and tension in multi-dog households.
