Our health testing levels for the Manchester Terrier (Toy)
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 5 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Progressive Retinal Atrophy (PRA)(PRA)
Augen
Progressive Retinal Atrophy (PRA) is an inherited eye disease that affects the retina, which is the light-sensitive layer of tissue at the back of the eye. In this condition, the specialized cells responsible for detecting light, known as photoreceptors, gradually degenerate and die. Because these cells cannot recover or be replaced, the disease slowly but inevitably leads to complete blindness.
Passing: CLEAR
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
Legg-Calvé-Perthes disease(LCPD)
Bewegungsapparat
Legg-Calvé-Perthes disease is a serious orthopedic condition affecting the hip joint, primarily in small breed dogs. It occurs when the blood supply to the head of the thigh bone, known as the femur, is spontaneously disrupted. Without blood, this bone tissue dies and collapses, leading to severe joint inflammation and pain.
Roentgen · Passing: A
Juvenile Dilated Cardiomyopathy(JDCM)
Herz
This is a severe, inherited heart disease where the heart muscle becomes abnormally enlarged and weakened, preventing it from pumping blood effectively. It is an autosomal-recessive condition that primarily affects young Portuguese Water Dogs and Toy Manchester Terriers. In Toy Manchester Terriers, the disease is linked to a mutation in a cardiac potassium channel, which is a protein essential for maintaining a normal heart rhythm.
Passing: CARRIER
Hypothyroidism
Hormonelles und Stoffwechsel
Hypothyroidism is an endocrine disorder where the thyroid gland, located in the neck, fails to produce enough thyroid hormones. These hormones are essential for regulating the body's metabolic rate, which is the speed at which cells convert nutrients into energy. When hormone levels are too low, the dog's entire metabolism slows down, affecting multiple organ systems.
Koerperfluessigkeiten · Passing: Normal
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
