Our health testing levels for the Malchi (Maltese x Chihuahua)
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 4 additional clinically recommended screenings that reduce risk in this breed.
In addition to mandatory tests:
Tracheal collapse(TC)
Atmung
Tracheal collapse is a progressive respiratory condition where the C-shaped cartilage rings that keep the windpipe (trachea) open begin to weaken and flatten. As these supportive rings lose their rigidity, the airway narrows, making it difficult for air to pass smoothly into the lungs. This mechanical failure of the respiratory tract leads to chronic irritation and breathing difficulties.
Roentgen · Passing: Normal / Unaffected
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
Myxomatous mitral valve disease(MMVD)
Herz und Kreislauf
Myxomatous valve degeneration is a chronic heart disease where the heart valves, most commonly the mitral valve, gradually thicken and lose their normal shape. This structural change prevents the valves from closing tightly, causing blood to leak backward through the heart chambers. Over time, this backflow forces the heart to work much harder, eventually leading to congestive heart failure.
Ultraschall · Passing: NORMAL
Glycogen storage disease type Ia(GSD Ia)
Stoffwechsel
Glycogen storage disease type Ia is an inherited metabolic disorder affecting the liver and kidneys. It is caused by a deficiency in a key enzyme needed to break down stored sugar, known as glycogen, into glucose for energy. Without this enzyme, glycogen builds up to damaging levels in these organs while the rest of the body suffers from a severe lack of fuel.
Passing: CLEAR
These levels are a comparison framework, not an official certification. They help compare breeding programs at a glance.
