History and origin
The FCI standard says it is a breed that has existed for several centuries. These dogs probably accompanied the Illyrians on their migration through Istria and the Dalmatian islands and settled in the Slovenian region of the Karst plateau. The breed is first mentioned in writing in 1689, in Baron Janez Vajkart Valvasor's book “The Glory of the Duchy of Carniola”.
The breed was officially recognised on 2 June 1939, under the name “Illyrian Shepherd”, at the FCI general assembly in Stockholm. Until 16 March 1968, the shepherd dog of the Karst bore the same name as the one from the Šar mountains. Then the Central Society of Yugoslavia gave them separate names: “Karst Shepherd Dog” and “Šarplaninac”.

Training and socialisation
The standard describes it as having a good temperament, moderately sharp, courageous and brave, but not a biter, very devoted to its owner. It is an incorruptible guard and distrustful of strangers.
It is also a pleasant, obedient companion, but it keeps a strong personality.
Tips for effective training

- Give it a territory. It is a guard by nature.
- Ask a trainer for help. Especially if you have no experience with guard dogs.
Activity needs and lifestyle
It is a robust mountain dog that needs daily walks and a large, fenced yard where it can guard its territory.
| Activity | How often | Why it matters |
|---|---|---|
| Walks on the lead | daily | Exercise and socialisation |
| Time in a fenced yard | daily | It guards its territory |
| Hikes | occasionally | It is a mountain dog |
Tips for a balanced life

Care and health
Coat and skin care
The long coat, with its abundant undercoat, is brushed several times a week, and daily during moulting periods.
Common health problems
There are no published health studies for the breed and no known breed-specific diseases. As with any large dog, it is worth watching for:
| 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
- Check the ears regularly.
- Check for ticks after outings in nature.
- Trim the nails if they do not wear down on their own.
Diet and nutrition
A large dog needs food suited to large breeds, especially while it is growing.
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) |
|---|---|---|---|
| 25 kg | 1,250 kcal | 1,410 kcal | 310–400 g |
| 33 kg | 1,540 kcal | 1,730 kcal | 380–490 g |
| 42 kg | 1,850 kcal | 2,080 kcal | 460–590 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. The body also reaches its adult form later than in small breeds.
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. Socialisation starts in the first weeks: gentle handling, everyday noises and new people.
