Our health testing levels for the Miniature Bull Terrier
We group breeding programs into three levels based on testing depth. Ask your breeder directly which level they meet.
A breeder at the Great level performs all mandatory tests plus 3 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Lens luxation(PLL)
Augen und Sehvermögen
Lens luxation is an inherited eye disorder where the lens slips out of its normal position because the supporting fibers holding it in place weaken or break. When the lens shifts, it can block the natural drainage of fluid within the eye. This blockage causes a rapid, painful buildup of pressure called glaucoma, which can lead to permanent blindness if left untreated.
Augen · Passing: Clear or Carrier
Persistent pupillary membranes (PPM)(PPM)
Augen und Sehvermögen
Persistent pupillary membranes (PPM) occur when tiny blood vessels that nourish the eye's lens before birth fail to break down and disappear as they normally should. This leaves behind delicate strands of tissue that stretch across the iris, which is the colored part of the eye, and the pupil. In some cases, these strands can attach to the cornea, the clear outer layer of the eye, or the lens.
Augen · Passing: CLEAR
Patellar Luxation(PL)
Bewegungsapparat
Patellar luxation, also known as a luxating patella, is a physical condition affecting the knee joint where the kneecap slips out of its normal groove. This misalignment interferes with the mechanical movement of the hind leg and can cause the joint to lock. Over time, this abnormal friction can lead to painful joint wear and tear, known as osteoarthritis.
Physisch · Passing: Grade 0 or 1
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
