History and origin
The FCI standard says this dog developed from very ancient times in the Serra da Estrela mountains, and its true origin has been lost over time. It can be considered one of the oldest breeds of the Iberian Peninsula. It climbs from the foothills almost to the summit, at about 2,000 m, especially in summer, when the flocks look for green pastures.
Its qualities were gradually recognised, and from the second half of the 20th century the breed spread all over the world. Wikipedia says the Portuguese breed association was founded in Lisbon in December 1986 and that in the 21st century some dogs protect flocks from the Iberian wolf, itself a protected species.

Physical characteristics
The standard describes it as a large, rustic and massive mastiff-type molossoid, with a lively gait and an impressive bearing. There are two coat varieties: long and short. The gaze is lively, calm and expressive.
General appearance
The head is strong, voluminous and long. The AKC says the breed has a few distinctive features: “rose” ears, a black mask and a hook at the end of the tail. The thick coat is similar in texture to goat hair.
| Feature | Estrela Mountain Dog |
|---|---|
| Size | Very large |
| Height at the withers | males: 65–73 cm; females: 62–69 cm |
| Weight | males: 45–60 kg; females: 35–45 kg |
| Coat | Long or short, like goat hair |
| Head | Strong, voluminous, with a dark mask |
| Tail | With a hook at the end |
The typical colours are yellow, fawn and grey, solid, in all shades, wolf grey or brindle. A dark mask on the face is typical. White markings are allowed only in small areas specified by the standard, such as the tips of the feet.
Training and socialisation
The standard describes it as the shepherd's inseparable companion and the faithful guardian of the flock, a wonderful guard dog for farm and home, distrustful of strangers and docile with its owner.
The AKC says socialisation and training from puppyhood are very important, so that its naturally dominant nature does not turn into aggression. With its family, and especially with children it knows, it can be very playful.
Tips for effective training
- Socialise it as a puppy. The AKC says this is very important given its dominant nature.
- Be calm and consistent. Such a big dog needs a confident owner.
- Introduce guests. It is distrustful of strangers.
- Teach it tricks. The AKC recommends tricks as exercise in bad weather.
Activity needs and lifestyle
The AKC says it is a relatively calm breed. If it is not working with a flock, play in a fenced yard and daily walks are enough. In bad weather it can exercise indoors, with a ball or by learning new tricks.
| Activity | How often | Why it matters |
|---|---|---|
| Daily walks | daily | Exercise for a big dog |
| Time in a fenced yard | daily | It guards its territory |
| Tricks and indoor games | in bad weather | Mental activity |
Tips for a balanced life
- It is not suited to flat life.
- The fence must be solid and high.
- Keep a cloth to hand: it drools quite a lot.
Care and health
Coat and skin care
The AKC says the thick coat, like goat hair, needs weekly brushing and an occasional bath. The nails grow quickly and must be trimmed regularly.
Common health problems
The AKC says most dogs are healthy, and good breeders have their dogs genetically tested. As with any very large dog, the following are worth watching:
| Condition | Description | Common symptoms |
|---|---|---|
| Hip dysplasia | The hip joint forms incorrectly and, over time, arthritis develops | Limping, difficulty getting up or jumping, hip pain |
| Gastric dilatation-volvulus (bloat) | The stomach fills with gas and may twist; this is a veterinary emergency | Swollen belly, trying to vomit without success, drooling, restlessness |
Other care
- Trim the nails regularly: they grow quickly.
- Check the ears and teeth weekly.
- Look for ticks after days spent outdoors.
Diet and nutrition
For such a big dog, the portion should be set according to its actual weight. Puppies need food for giant breeds, so that they grow slowly and steadily.
Tips for a healthy diet
The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.
| Dog's weight | Calories per day (neutered) | Calories per day (not neutered) | Dry food per day (approximate) |
|---|---|---|---|
| 35 kg | 1,610 kcal | 1,810 kcal | 400–520 g |
| 45 kg | 1,950 kcal | 2,190 kcal | 490–630 g |
| 60 kg | 2,410 kcal | 2,720 kcal | 600–780 g |
- Split the food into two meals a day to reduce the risk of bloat.
- Do not let it run right after a meal.
- A dog is at the right weight when you can feel its ribs under the coat without pressing hard.
Foods to avoid
Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.
Reproduction and development
Physical and emotional maturity
In dogs, sexual maturity usually comes between 6 and 12 months, but in large breeds it can be delayed until about two years. Very large breeds become adults only at around 2 years.
Mating and pregnancy
Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.
Caring for the puppies
In large breeds, a litter has around 7 puppies on average. The puppies grow very fast, so they need growth food suited to large breeds. Socialisation starts in the first weeks.
