Molosser / FCI Group 2 · Purebred · Uruguay's only native breed — a powerful, loyal guardian forged on the South American pampas from feral colonial dogs
The Cimarrón Uruguayo is Uruguay's only native dog breed and its official national dog — a powerful molosser descended from dogs brought by Spanish and Portuguese colonizers in the 16th and 17th centuries. These dogs went feral on the Uruguayan pampas, adapting over generations to the harsh landscape through natural selection. They were eventually domesticated again by Uruguayan gauchos who valued their strength, courage, and loyalty as cattle herders, hunters, and guardians. FCI recognized the breed in 2006.
Real Cimarrón Uruguayo photos — showcasing their unique appearance and character.
Loyal, brave, and territorial. The Cimarrón Uruguayo is deeply devoted to its family but reserved and wary with strangers — traits forged over centuries of feral survival. It bonds strongly with its owner and can be affectionate at home, but its guarding instincts are always present. Experienced owners only; early socialization is essential.
Medium to high energy: needs 60–90 minutes of vigorous daily exercise. Suited to active rural or suburban life with space to move. A working breed at heart — thrives when given a purpose, whether herding, tracking, or guarding. Not suited to apartment living.
Short, dense, easy-care coat. Minimal grooming required — a weekly brush keeps the coat clean and removes loose hair. Bathe only as needed. Ears should be checked regularly; nails trimmed monthly.
Intelligent and responsive to confident, consistent leadership. Early obedience training and thorough socialization from puppyhood are non-negotiable for this breed. Responds best to firm, positive, and patient handling. Not recommended for first-time dog owners due to its dominant, independent streak.
A generally healthy, hardy breed shaped by centuries of natural selection. Watch for hip dysplasia common in larger molossers, bloat (GDV) in deep-chested individuals, and skin conditions in hot, humid climates. Choose breeders who screen for hip health.
The Cimarrón Uruguayo does best on a good-quality complete dog food matched to its age, size, and activity level. As a rough guide, a typical adult eats about 2½–3¾ cups of dry food per day, split into two meals — but a hard-working or very active dog needs more, while a couch companion needs less. Use a large-breed formula and avoid heavy exercise right after meals to reduce the risk of bloat.
Puppies: 3 meals a day of a puppy formula to fuel growth.
Active adults: around 2½–3¾ cups daily, in two meals, adjusted to keep a trim waistline.
Seniors (7+ yrs): slightly fewer calories and, if needed, a joint-supporting formula as they slow down.
Never feed chocolate, grapes or raisins, onions, garlic, xylitol, macadamia nuts, or cooked bones. Keep treats to no more than about 10% of daily calories so they don't crowd out balanced nutrition or lead to weight gain.
Where puppies are available, a Cimarrón Uruguayo from a responsible breeder typically costs around $1,000–$2,500, with rarer bloodlines and imported dogs sitting at the higher end. Rescue or adoption, where possible, is far less — usually a few hundred dollars in fees.
Food, treats & preventatives, routine care and supplies together usually run about $110–$200 per month for a healthy adult, not counting emergencies or boarding.
Over a full lifetime the total cost of ownership generally lands around $18,000–$28,000, including the purchase price. Pet insurance ($15–$45/month) and a small emergency fund are smart ways to cushion against unexpected veterinary bills.
