Campeiro BulldogCharacteristics, history, training and care

The Campeiro Bulldog descends from bulldogs brought to Brazil by European immigrants and developed in the south of the country. The word “campeiro” means “from the fields”, in other words from the countryside.

It was used to find, catch and drive cattle that had strayed into fields and forests, and also as a guard and companion for country people. It was also used in slaughterhouses. When this was banned in the 1970s, the breed almost disappeared. A private rescue programme began in the mid-1970s.

How the breed developed

• The period of European immigration – European immigrants bring bulldogs to southern Brazil.
• 1970s – The use of dogs in slaughterhouses is banned, and the breed almost disappears.
• Mid-1970s – A private programme to save the breed begins.
• 2001 – The Brazilian Kennel Club recognises the breed.
• 2025 – The FCI recognises the breed provisionally.

Indicative rating: 5 stars means the highest level. The breed has no AKC profile; the rating is based on the FCI standard (“calm, vigilant, very docile, barks little”).

It is a medium-sized, short-haired, compact, sturdy and imposing dog. The head is broad, with strong jaws; the lower jaw juts slightly forward, just enough to hold an ox.

General appearance

The muzzle is broad and strong, neither too short nor too long. The small, triangular ears hang or fold backwards. The tail is short from birth and thick at the base.

The standard accepts all colours except merle (an irregularly mottled coat).

The standard describes it as very docile and easily adaptable, controllable, calm and barking little. Its temperament should be firm and controlled, so that it always obeys its owner.

Wikipedia notes that it can be aggressive towards other dogs, so early socialisation is important.

Tips for effective training

• Socialise it early with other dogs. This is the most important thing for this breed.
• Be calm and consistent. It obeys a confident owner well.
• Use rewards. It is docile and learns easily.
• Supervise meetings with unfamiliar dogs. Especially with dogs of the same sex.

It has moderate energy. Daily walks and play in the yard are enough.

Tips for a balanced life

• In summer, avoid exertion in the hottest hours.
• The fence must be solid.
• It suits a family that can supervise meetings with other dogs.

Coat and skin care

The short, smooth coat is very easy to look after, with a brush once a week.

Common health problems

There are no known hereditary diseases specific to the breed. The standard disqualifies dogs with breathing difficulties, to keep the breed healthy.

Other care

• Trim the nails regularly.
• Check the ears and teeth once a week.
• Protect it from intense heat.

A muscular dog needs good-quality food. Keep an eye on its weight so that it does not get fat.

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.

• Give it its food in two meals a day.
• Fresh water should always be available.
• A dog is at the right weight when you can feel its ribs 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.

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.

• “Campeiro” means “from the fields”. The name links the breed to the rural setting in which it developed.
• Jaws made for cattle. The lower jaw juts slightly forward, just enough to hold an ox.
• It barks little. The standard describes it as a calm dog that barks little.
• Saved from extinction. After its use in slaughterhouses was banned, the breed almost disappeared.
• A tail short from birth. The standard calls for a naturally short tail.
