While many dogs can live happily with just their humans, some breeds truly flourish with a canine buddy by their side. Whether it’s for play, emotional support, or just some good old-fashioned tail-chasing, these dog breeds are known to thrive when they’re part of a duo. If you’re considering getting a second dog, this list might help you find the perfect pair! Sometimes, the right companion can completely transform a dog’s behavior and mood.
1. Labrador Retrievers – Playful and People-Oriented
Labs are famously friendly, outgoing, and high-energy dogs that love constant interaction. While they adore human attention, they can become bored or anxious if left alone for long periods. That’s where a canine companion works wonders. When paired, Labs tend to burn off energy playing together and are much less prone to destructive behavior. Their easygoing nature also makes them great at adapting to new pack members. They’re the type of dog that thrives on a balance of play and companionship, especially with a fellow fun-lover.
2. Beagles – Social Sniffers with a Pack Mentality
Originally bred to hunt in packs, Beagles are one of the most social breeds out there. They crave companionship and do their best when they have a four-legged friend to share their day with. Beagles communicate constantly through their expressive barks and body language, and having a buddy allows them to engage in this natural behavior. Two Beagles can keep each other mentally and physically stimulated, especially on scent-tracking adventures around the yard. You’ll find their teamwork surprisingly clever—and sometimes hilariously mischievous.
3. Border Collies – High-Energy Brains That Need a Buddy
Border Collies are incredibly smart and need both mental and physical exercise daily. When kept alone, they can easily become bored and turn to undesirable habits like herding furniture (yes, really). But with a similarly energetic companion, they thrive. Two Collies—or even a Collie with another playful breed—can keep each other engaged with endless games, problem-solving, and exercise, making for a happier home overall. It’s like watching two geniuses invent new games on the fly every day.
4. Golden Retrievers – Gentle Souls Who Love Company
Golden Retrievers are affectionate, loyal, and generally easygoing. While they love their humans dearly, they also bond strongly with other dogs. They often take on a nurturing role and tend to get along with most breeds. A pair of Goldens can often be found sleeping paw-to-paw or running side-by-side in the yard. Their calm nature means they won’t usually compete for dominance, making cohabitation smooth and joyful. They’ll often even share toys and treats without any fuss at all.
5. Dachshunds – Brave Little Dogs Who Hate Being Alone
Despite their small stature, Dachshunds are bold, clever, and incredibly attached to their families—including furry siblings. They’re prone to separation anxiety when left solo, so having a companion can ease their stress. Dachshunds are particularly known to form tight-knit bonds with dogs they grow up with, especially other Dachshunds. Whether it’s snuggling under blankets or barking in tandem, these pups do better in pairs. Just be ready for double the sass in those tiny sausage bodies!
6. Siberian Huskies – Pack Dogs With Boundless Energy
Huskies were literally born to run in packs, and that instinct hasn’t gone anywhere. They thrive on interaction, whether it’s with humans or other dogs, but often feel most at ease with their own kind. Huskies in pairs (or even larger groups) tend to exercise more, howl less, and generally cause less mischief—because they’re too busy entertaining each other. Watching them sprint and wrestle together is like witnessing pure joy in motion.
7. Cavalier King Charles Spaniels – Affectionate Companions Who Prefer Company
These sweet, gentle little dogs are known for their devotion to their humans, but they’re just as happy bonding with fellow pups. They’re sensitive avian companions and can become depressed if left alone for too long. Cavaliers in pairs are more relaxed, less anxious, and love curling up together for cozy naps. Their mild temperaments also make it easy to introduce them to other small breeds or even slightly larger ones. Having a buddy around gives them an added layer of emotional security.
8. Australian Shepherds – Smart Workers Who Need a Playmate
Aussies are bright, agile, and driven—traits that make them amazing working dogs, but also ones that can lead to restlessness if they don’t get enough activity. A fellow energetic dog helps keep them busy, whether it’s through roughhousing, agility training, or shared herding games. Aussies often form strong bonds with canine siblings and love having a job or game to do together, turning any backyard into an adventure playground. Without a friend, their energy can turn chaotic fast.
9. Pugs – Clownish Cuddlers Who Hate Loneliness
Pugs are goofy, affectionate dogs who adore being around others. While they’re happy in human laps, they really blossom when they have a fellow pug—or similarly mellow breed—to snuggle and play with. They’re not big on alone time, and many pug owners find that their dogs are far more content and less needy when they’ve got a buddy to share their space (and their snacks). Two pugs together often act like a tiny comedy duo that lives for love and laughter.
10. Shih Tzus – Loyal Lapdogs Who Love a Sibling
Shih Tzus are famously loyal and tend to develop strong attachments to both people and other pets. While they’re fine solo, they’re happiest when they have a companion to share their world with—especially another Shih Tzu. These dogs often mirror each other’s behaviors, from grooming rituals to playtime routines, and they absolutely love cuddling together. In fact, many Shih Tzu pairs become inseparable, forming lifelong, loving bonds. Their gentle nature makes them a perfect match for cohabiting in peace.
11. Bichon Frises – Cheerful Charmers That Crave Companionship
Bichon Frises are bubbly, affectionate dogs with a flair for fun—and they absolutely hate being left alone. Their cheerful disposition makes them quick to bond with both humans and fellow canines. Having a buddy not only eases their anxiety but also enhances their naturally playful spirit. Two Bichons can spend hours chasing each other around the house, playing tug-of-war, or napping side-by-side like fluffy clouds. Their social nature means they flourish in pairs, especially when matched with similarly gentle or fun-loving breeds.
12. Cocker Spaniels – Sensitive Sweethearts Who Bond Deeply
Cocker Spaniels are gentle, affectionate dogs with soulful eyes and even bigger hearts. They’re known for forming deep emotional attachments—not just with people, but also with fellow dogs. A pair of Cockers will often mirror each other’s moods and routines, providing comfort, play, and companionship. Their sensitive nature means they don’t handle loneliness well, but having a buddy helps keep their tails wagging and their anxiety low. Whether they’re exploring the yard or curled up together after a walk, these pups truly thrive in pairs.
