The original developer of the breed was a Bull Terrier breeder named Pedro Pessoa Ribeiro Dantas from Caxias do Sul, Rio Grande do Sul.
In 1978, his neighbor asked him to mate one of his Bull Terrier males with the neighbor's female Boxer.
Pedro took one of the female puppies from this mating, and named her Tigresa after the brindle markings on her coat.
As Tigresa grew, she turned out to be a very pleasant and promising individual: she was extremely affectionate, obedient, quick-to-learn, physically balanced, strong, and vigorous.
Moreover, she lacked the extreme characteristics typical to the modern Bull Terrier, being much more functional and agile.
She was also physically stronger than both an average Bull Terrier and an average Boxer.
At the same time she was an excellent guard and very tolerant towards Pedro's Bull Terriers: when they tried to provoke her, she rather eluded the attacks by her better physical agility and balance than by using aggression.

After noticing the great qualities of Tigresa, Pedro started to gather information from other people who had purchased a puppy from the same litter.
The response was that the dogs had become physically vigorous and excellent guards, at the same time being gentle and affectionate towards their families.
Therefore, another mating between a different Bull Terrier and a Boxer.
Because the results turned out to be as positive as in the first litter, a new breeding line was decided to be established and was originally named Bull Boxer (which should not be confused with the English designer breed with the same name based on a Staffordshire Bull Terrier x Boxer cross).

After the first generation of Bull Terrier x Boxer crosses consisting of 80 individuals, Pedro continued by occasional matings between these crosses.
The qualities and health of the new puppies were followed during their growth.
It was noticed that a vast majority of them possessed the following characteristics:
Extremely efficient guardian
Balanced temper and extremely attached to his family
Physically balanced and powerful, with the extreme pain tolerance of the Bull Terrier
Longevity, lifespan being approximately 13 years
Although the results were promising, Pedro was not yet sure if the same results could also be achieved by using other similar kinds of breeds.
Therefore, he crossed several Bull Boxers with the American Staffordshire Terrier and noticed that at least in the first generation, the characteristics remained the same.
However, no more American Staffordshire Terrier crosses were made in the following generations and soon the studbook was closed in order to continue the breeding solely by using already existing Bull Boxers.

The Brazilian Bull Boxer Club was founded in 1986 and its president is Pedro Ribeiro Dantas himself.
The breed was officially accepted by the CBKC in 1999 and the today's version of the breed standard was published in 2007.
Nowadays there are 2000 pure-bred dogs in the official registry of the Bull Boxer Club - however, the number also includes many dogs that have already died.
There are breeders in many different states of Brazil and the breed has grown popularity since the 1990s.
Although the Brazilian Dogo is not recognized by the FCI, it does not bother Brazilian breeders and fanciers of the breed: actually, the president of the Bull Boxer Club has stated that the FCI's current principles do not meet with the breeding philosophy of the Dogue Brasileiro.
