Our health testing levels for the Manchester 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 6 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
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: Normal
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: Normal
Pattern baldness
Haut und Fell
Pattern baldness is a cosmetic, genetically influenced condition affecting the skin and coat. It occurs when hair follicles gradually shrink over time, leading to localized hair loss. Because there is no underlying inflammation or infection, the skin itself remains healthy and unaffected.
Haut
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: Clear/Carrier
Hydrocephalus
Nervensystem
Hydrocephalus is a neurological condition affecting the brain and nervous system, commonly referred to as water on the brain. It occurs when cerebrospinal fluid, the natural protective liquid surrounding the brain, builds up abnormally inside the brain's cavities, known as ventricles. This accumulation creates harmful pressure on the surrounding brain tissue, which can impair normal brain function.
