Introduction
The Rafeiro do Alentejo (pronounced hah-FAY-roh doo ah-len-TAY-zhoh) is a majestic estate and herd guardian dog that proudly hails from Portugal. Commonly known as Portuguese Mastiffs or Alentejo Mastiffs, these impressive canines embody the powerful and vigilant presence needed for their historic role as protective sentinels.
Rafeiros Alentejanos are a formidable giant breed, standing tall between 25 and 29 inches and weighing an impressive 75 to 130 pounds or more. Their broad, bear-like heads complement their muscular, sturdy bodies, and their distinctive gait—a "heavy, slow roll" as described by the breed standard—speaks to their strong and deliberate nature.
One fascinating trait of this breed is their tendency to be more active during the night, an invaluable characteristic when guarding flocks of sheep and cattle under the cover of darkness.
Despite their imposing size and traditional working roles, Rafeiro do Alentejo dogs are gentle giants at heart — calm, affectionate, and capable of flourishing as devoted companions within the right family environment.
Caring for a Rafeiro do Alentejo
Though Rafeiros Alentejanos were originally bred to protect livestock, they adapt beautifully to life as cherished family members, provided their unique needs are thoughtfully met.
Given their giant stature, a spacious home with ample room both indoors and outdoors is essential for their comfort. While not overly hyperactive, these dogs thrive on consistent daily exercise, best enjoyed outside where they can stretch their legs and engage their senses.
Because of their guardian instincts, all outdoor activity should be confined to a leash walk or, preferably, within a securely fenced yard to keep them safe and prevent roaming.
Highly intelligent and eager to learn, Rafeiros Alentejanos benefit most from responsible owners experienced with large breeds. Early socialization and a lifelong commitment to positive, consistent training are crucial to nurturing their best behavior.
Since Rafeiros Alentejanos are natural guardians, always ensure their outdoor time is safe by using a leash or a well-enclosed yard.
Regarding children, this breed is best suited for families with older kids who understand how to respectfully and safely interact with large dogs. When it comes to cohabiting with other pets, Rafeiros do best when they have the chance to grow up alongside their furry housemates.
Their short, thick, straight coat sheds steadily but calls for only minimal grooming. Like many large mastiff-type breeds, they are also known to drool moderately.
Rafeiro do Alentejo Health Issues
With an average lifespan of 12 to 14 years, the Rafeiro do Alentejo outlives many typical giant breeds, reflecting robust health overall.
While generally hardy, these dogs can be susceptible to certain health concerns common in large breeds, making it vital to choose a reputable breeder who prioritizes health and longevity.
Hip Dysplasia
Hip dysplasia is a frequent ailment in large dogs where the hip joint forms improperly, leading to looseness and degenerative joint disease, or osteoarthritis. Mild cases may respond well to anti-inflammatory medications, but severe cases often require surgical intervention.
Watch for these common symptoms of hip dysplasia:
- Limping or favoring one leg
- Hesitancy to rise, jump, or climb stairs
- Shifting weight predominantly to front legs
- Noticeable muscle loss in the hind limbs
- Observable discomfort or pain in the hips
Bloat
Bloat occurs when the stomach becomes distended by a buildup of gas and food, and it can escalate into a life-threatening condition known as gastric dilatation-volvulus (GDV). In GDV, the stomach twists, cutting off its blood supply and that of nearby organs such as the spleen.
GDV is an acute emergency marked by severe pain and is especially prevalent in large, deep-chested breeds like the Rafeiro do Alentejo.
Recognize the signs of bloat and GDV, which include:
- Unproductive retching or dry heaving
- Swollen or distended abdomen
- Sudden restlessness, pacing, or inability to find comfort
- Heavy panting
- Excessive drooling
- Weakness or collapse
Seek emergency veterinary care immediately if your dog displays any of these symptoms.
Preventative options such as a gastropexy—surgically attaching the stomach to the abdominal wall—can be performed while your dog is young, often alongside spaying or neutering, to reduce the risk of future twisting. Discuss this preventative measure with your veterinarian.
What To Feed a Rafeiro do Alentejo
Collaborate closely with your veterinarian to select a high-quality diet tailored to your dog’s specific needs. Your vet can recommend foods meeting the Association of American Feed Control Officials (AAFCO) standards that provide complete and balanced nutrition suitable for your dog’s age, size, and health profile.
Rafeiro do Alentejo puppies flourish on puppy formulas designed for large breeds, while adult dogs should transition to mature large-breed diets to maintain optimal health.
How To Feed a Rafeiro do Alentejo
Adult Rafeiro do Alentejo dogs usually do well with two meals daily—once in the morning and once in the evening.
Puppies, on the other hand, may require three to four smaller meals a day to meet their growing nutritional demands. Your veterinarian can advise you on the most effective feeding schedule for your pup’s development stage.
To help minimize the risk of bloat and GDV, consider these mealtime strategies:
- Use slow-feeder bowls to prevent rapid eating
- Avoid vigorous exercise just before or after meals
- Refrain from using raised food bowls, as these may increase bloat risk
- Divide daily food portions into smaller, frequent meals rather than one large serving
How Much Should You Feed a Rafeiro do Alentejo?
Begin with the feeding guidelines on your dog food packaging, which provide portion recommendations based on weight.
For more tailored advice, consult your veterinarian, who will factor in your dog’s age, weight, body condition, activity level, and any specific health considerations.
Remember to keep treat intake within 10% of daily caloric needs to avoid overfeeding while enjoying rewarding your dog appropriately.
Nutritional Tips for Rafeiro do Alentejo Dogs
If your dog is fed a complete, balanced, and AAFCO-compliant diet, additional supplements are generally unnecessary.
However, certain conditions might benefit from specific supplements, so always seek your veterinarian’s guidance before adding any nutritional enhancements to your dog’s regimen.
Rafeiro do Alentejo Personality and Temperament
Welcoming a towering 130-pound guardian into your household can be both exciting and intimidating. Fortunately, Rafeiros Alentejanos who receive proper socialization and training grow into devoted, confident, and composed companions.
Keep in mind that while training shapes behavior, the breed’s innate guardian instincts will always be present. Expect a loyal protector who is warm with family but reserved with strangers, enjoys patrolling a fenced yard, and may alert you vocally to new or unusual occurrences.
Rafeiro do Alentejo Behavior
Smart and purposeful, Rafeiros Alentejanos excel as working dogs. Without sufficient outlets for their energy and intelligence—such as daily exercise and mental stimulation—they can develop undesirable behaviors like excessive barking or destructive chewing.
Though their energy is moderate, they do require consistent physical activity confined to a leash or a securely fenced area to keep them safe.
Rafeiro do Alentejo Training
Early and continuous socialization is critical for Rafeiro do Alentejo puppies. Introducing them safely to a wide range of animals, people, environments, and stimuli during the formative first 16 weeks lays a solid foundation for a well-adjusted adult.
Speak with your breeder about their socialization approach and seek your veterinarian’s recommendations for age-appropriate social experiences.
These dogs are intelligent and capable; however, their independent streak—rooted in years of working as solitary guardians—means training may present challenges. Remember that consistent, positive reinforcement using treats, play, and praise is the most effective way to nurture cooperation and obedience.
Training sessions also offer valuable mental and physical engagement, further strengthening the bond between you and your dog.

Skin Care
Regular brushing removes debris like twigs and burs that can irritate skin beneath the thick coat. If your dog shows signs of itching or skin changes, consult your veterinarian promptly.

Flea and tick prevention is essential, especially given this breed’s affinity for the outdoors. Work with your vet to select the safest and most effective preventatives.
