The Exotic bloodline is built on three South African families of Boerboels.
Ysterberg · Baden · Dopper — the foundation families whose blood is expressed in every generation of our dogs to this day.
We are talking world-class Boerboel producing families — a heavy concentration of the same stud dogs expressed in every generation of our dogs.
The goal of the program is simple: take the bloodline's inherited strengths — drive and athleticism — and add them to unrelated or distantly related males, consistently producing and maintaining hybrid vigor.
The foundation stock of the Exotic bloodline is tight and heavily concentrated. If you know how to use a pedigree database, look for yourself — almost every new line traces back to some of these names.

Where the blood comes from
Three South African families set the type, the drive and the size behind every Exotic Boerboel — each represented today by one foundation dog.
01
Substance & bone
Baden
A foundation family prized for substance, bone and the broad, dependable head of the old-school Boerboel. Baden blood anchors the type that runs through every Exotic litter.

02
Size & drive
Mouzer · Ysterberg
The Ysterberg Mastiff line built by farmer Klaas Van Waveren — bigger, more functional and more robust than the average Boerboel, with deep genetic variation bred in for hybrid vigor.

Athletic & sound
Dopper
The Dopper stud names carry working drive, athleticism and soundness. Old-school Dopper females sit at the heart of the Exotic breeding program to this day.

Two foundation females and the foundation male the whole program is built from — and one playbook repeated three ways: concentrate the blood of a single great ancestor until it stamps every litter. The heatmap below tints every ancestor by how many times it recurs — the hotter the colour, the heavier the line breeding.
From the farm to four registries
The story of the bloodline is also the story of the breed itself — and, in 2016, of a split that still defines it.
The farm guardian of South Africa
On isolated South African farms, the Boerboel is shaped as a working guardian — a mastiff bred for nerve, loyalty and the strength to stand alone.
Klaas Van Waveren builds the Ysterberg Mastiff
Said to combine as many as fourteen breeds, the Ysterberg Mastiff is engineered to be bigger, more functional and more robust — carrying wide genetic variation that a breeder can use to add flavour while holding size and drive.
Three families set the type
Baden, Dopper and Mouzer · Ysterberg lines concentrate the prepotent producers — Ysterberg Vegter 3, Corma Buks, Cabaret Klein Buks, Dopper Oubaas — into a tight, repeatable foundation.
The breed splits into four classifications
Politics fractures the Boerboel into four registries. History records that the Ysterberg Mastiffs were folded into the original standard — though larger, more agile and free of its health problems.
Two breeds, one inheritance
Stoffel Bloom, the modern conductor of the Ysterberg line, maintains the Ysterberg Mastiff is a separate breed living inside the Boerboel's makeup. Exotic carries that concentrated inheritance forward — adding drive and athleticism to unrelated males for consistent hybrid vigor.
The Ysterberg Mastiffs are not Boerboels. The Boerboel has the Ysterberg Mastiff in its makeup — they are two different breeds.
