10 Dog Breeds You Won’t Believe Are Related

The canine world is full of surprising family connections. You might be shocked to learn that a tiny Chihuahua and a massive Saint Bernard share the same ancestor. Or that a fluffy Pomeranian and a sled-pulling Samoyed are actually cousins. From towering giants to tiny lapdogs, the similarities and differences between these seemingly unrelated breeds are fascinating.

Greyhound & Whippet

You might recognize their sleek, aerodynamic builds, but while the Greyhound is much larger, the Whippet is essentially a smaller, more compact version. Both are sighthounds built for speed, yet their size difference makes them seem like distant cousins rather than close relatives.

Saint Bernard & Chihuahua

This one’s a head-scratcher. Saint Bernards are giant mountain rescue dogs, and Chihuahuas are tiny purse-sized companions. Both belong to the same broader canine family but couldn’t be more different in size, temperament, or purpose. The only thing they have in common? Four legs!

Great Dane & Dachshund

It’s hard to believe these two come from the same working dog lineage. The Great Dane is a towering, gentle giant, while the Dachshund is small and elongated, built to burrow and hunt. Yet, both share the same ancient roots in hunting and guarding.

Pekingese & Shih Tzu

Both hailing from China, the Pekingese and Shih Tzu are royal lapdogs with long, flowing coats. Despite their similar lineage, the Pekingese is smaller and stockier, while the Shih Tzu has a more elegant, refined look. Still, both were companions to emperors.

Samoyed & Pomeranian

You wouldn’t think the fluffy, bear-like Samoyed and the tiny, lively Pomeranian were related, but both come from Spitz-type breeds. The Samoyed was bred for sledding, while the Pomeranian’s job was to be cute and fluffy, but they share the same ancient northern heritage.

Mastiff & Pug

Believe it or not, these two breeds share common ancestors. The Mastiff is huge and muscular, while the Pug is small with a squished face and charmingly stubborn personality. Both were bred as guard dogs, though one does it a bit more fiercely than the other!

Saluki & Afghan Hound

At first glance, you might see their elegant stature, but their coats couldn’t be more different. The Afghan Hound has a long, flowing mane, while the Saluki’s coat is short and sleek. Still, both are ancient sighthounds bred for hunting in desert regions.

Corgi & German Shepherd

It’s hard to believe these two very different dogs share herding roots. The short-legged, fluffy Corgi was bred to herd cattle, while the German Shepherd is known for police work and guarding. Yet, they both excel in herding thanks to their shared working dog ancestry.

Bulldog & Boxer

Despite their obvious differences in appearance, Bulldogs and Boxers both come from the same line of working dogs. The Bulldog’s stocky build contrasts with the lean and muscular Boxer, yet they were both originally bred for guarding and strength, making them closer cousins than you’d think.

Basset Hound & Bloodhound

These droopy-faced hounds share the same lineage as scent-tracking masters, but while the Bloodhound is known for its towering stature and strong tracking abilities, the Basset Hound has shorter legs and a more laid-back vibe. Both, however, are pros when it comes to sniffing out a trail!
