The Cane Corso isn’t just a modern Italian breed; it is a living echo of ancient Roman war dogs (Canis Pugnax). A landmark 2017 study (Cell Reports) mapped the genetic architecture of modern dog breeds. By analyzing shared identical DNA strands inherited from a common ancestor, we can measure exactly how closely related other breeds are to the Cane Corso today.
How to Read the DNA Scores Below
| Genetic Link | Shared Base Pairs | Meaning |
|---|---|---|
| Very High | 150,000,000+ | Extremely close cousin – nearly sibling level |
| High | 50,000,000 – 150,000,000 | Strong shared ancestry |
| Moderate | 15,000,000 – 50,000,000 | Clear but more distant family connection |
What are “base pairs”? Think of the Cane Corso’s DNA as a blueprint with ~200 million pages (base pairs). When two breeds share a high number of identical base pairs, it means they both inherited those specific pages from a common ancestor—like two cousins inheriting the same grandmother’s eyes and jawline.
1. Neapolitan Mastiff (NEAP) – ~185,000,000 base pairs
Genetic Link: Very High
The Neapolitan Mastiff is the Cane Corso’s closest living relative by a huge margin. They share an astonishing 185 million identical base pairs—more than any other breed on this list.
Both descend directly from the Roman Canis Pugnax (war dogs). While the Cane Corso remained a lean, agile farm and hunting dog in Italy, the Neapolitan was bred for maximum mass and loose skin. Under the wrinkles, however, their DNA tells a simple story: they are virtually siblings.
2. Boxer (BOX) – ~60,000,000 base pairs
Genetic Link: High
The Boxer is a German breed, yet it shares 60 million base pairs with the Italian Cane Corso. How? The ancient Molossus DNA traveled north from Greece and Rome into Germany.
Both breeds kept the short muzzle, muscular build, and protective instincts of their shared ancestors. The Boxer simply swapped the Cane Corso’s solemn seriousness for playful, bouncy energy—but the genetic signature of the war dog is still there.
3. Bullmastiff (BULM) – ~40,000,000 base pairs
Genetic Link: Moderate
Developed in 19th-century England by crossing English Mastiffs with Bulldogs, the Bullmastiff shares 40 million base pairs with the Cane Corso.
Many people assume the English Mastiff is closer, but the data says otherwise. The Bullmastiff’s Bulldog ancestry preserved more of the original Roman “catch dog” instincts—traits that the Cane Corso also kept for boar hunting and farm guarding.
4. English Mastiff (MAST) – ~25,000,000 base pairs
Genetic Link: Moderate
The English Mastiff shares 25 million base pairs with the Cane Corso. This is a clear but more distant family connection.
Both trace back to the Molossus, but centuries of separate breeding in England vs. Italy pulled their DNA apart. The English Mastiff grew into a giant estate guardian, while the Cane Corso remained a medium-large all-purpose farm dog. Still, their shared loyalty and imposing presence are living echoes of the same ancestral dog.
5. Dogue de Bordeaux (DDBX) – ~15,000,000–20,000,000 base pairs
Genetic Link: Moderate (lower end)
The Dogue de Bordeaux (French Mastiff) rounds out the list with approximately 15–20 million shared base pairs with the Cane Corso.
This French breed shares the same Molossus roots but developed independently in southwestern France. The Dogue has an even shorter muzzle and a more massive head than the Cane Corso, but their genetic connection—while the most distant on this list—is still strong enough to confirm they belong to the same ancient family of European mastiff-type dogs.
Quick Comparison Table
| Breed | Shared Base Pairs (with Cane Corso) | Genetic Link | Origin |
|---|---|---|---|
| Neapolitan Mastiff | ~185,000,000 | Very High | Italy (Ancient Rome) |
| Boxer | ~60,000,000 | High | Germany |
| Bullmastiff | ~40,000,000 | Moderate | England (19th century) |
| English Mastiff | ~25,000,000 | Moderate | England |
| Dogue de Bordeaux | ~15,000,000–20,000,000 | Moderate | France |
Final Thoughts: What These Numbers Really Mean
The Cane Corso (European Mastiff) has a clear genetic family tree:
- The sibling: Neapolitan Mastiff (185M base pairs shared)
- The German cousin: Boxer (60M)
- The English relatives: Bullmastiff (40M) and English Mastiff (25M)
- The French cousin: Dogue de Bordeaux (15–20M)
Every breed on this list inherited the same guardian dog tool kit from their common ancestors: imposing presence, protective instincts, and deep loyalty. The numbers simply tell us how closely they remain related after centuries of separate breeding.

FAQ’s-Italian Cane Corso Heritage
Is a Cane Corso a Mastiff or a Molosser?
Both. The Cane Corso is a Molosser-type breed, which is the broader category of ancient guardian dogs. Within the Molosser family, it is classified as a Mastiff (specifically the Italian Mastiff). The study confirms its closest relatives are other European Mastiffs: Neapolitan, Bullmastiff, English Mastiff, and Dogue de Bordeaux.
Is a Cane Corso a good family dog?
Yes, but not for first-time owners. The Cane Corso is deeply loyal and protective of its family—a trait it shares with all its genetic relatives (Neapolitan Mastiff, Boxer, Bullmastiff). However, they require early socialization, firm leadership, and experienced handling. With the right owner, they are gentle giants at home and fearless guardians when needed.
Is a Cane Corso more aggressive than a Pitbull?
No, but they are more protective. Cane Corsos are not inherently aggressive, but they have a higher guarding instinct than Pitbulls. This instinct comes directly from their ancient Molossus war dog DNA (shared with breeds like the Neapolitan Mastiff). Pitbulls were bred for different purposes. Proper training makes all the difference in both breeds.
What health problems do Cane Corsos have?
Hip dysplasia is the most common—and it is shared with their genetic relatives like the Bullmastiff (40M base pairs) and English Mastiff (25M base pairs). Other concerns include bloating (gastric dilatation-volvulus), heart issues, and eyelid abnormalities. Responsible breeders screen for these conditions.
How long do Cane Corsos live compared to other Mastiffs?
Cane Corsos typically live 9–12 years, which is longer than most giant Mastiffs. For comparison:
- Neapolitan Mastiff (closest relative): 7–9 years
- English Mastiff: 6–10 years
- Dogue de Bordeaux: 5–8 years
The Cane Corso’s smaller, leaner frame (compared to giant mastiffs) contributes to its longer lifespan.
Cane Corso vs. English Mastiff – which is bigger?
The English Mastiff is significantly larger. English Mastiffs weigh 120–230 lbs, while Cane Corsos weigh 80–120 lbs. However, the Cane Corso shares 25M base pairs with the English Mastiff—a clear but distant genetic connection. Think of them as cousins: the English Mastiff is the giant relative; the Cane Corso is the lean, athletic one.
Cane Corso vs. Bullmastiff – which is better for protection?
Both are excellent, but they differ in style. The Cane Corso (40M base pairs shared with Bullmastiff) is more agile and was used for boar hunting and farm guarding. The Bullmastiff was bred specifically to catch and hold poachers. For home protection, either works, but the Cane Corso is better for active families, while the Bullmastiff suits a more stationary guardian role.
