Our health testing levels for the Catahoula Leopard Dog
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:
Eye conditions (ophthalmological eye exam)(ECVO)
Augen und Sehvermögen
This refers to a variety of hereditary eye conditions affecting the structures of the eye, such as the lens, retina, or eyelids. An ophthalmological eye exam is a specialized clinical screening used to detect these genetic defects, which include cataracts (clouding of the lens) or progressive retinal atrophy (gradual degeneration of the light-sensitive retina). Early detection through these screenings helps identify issues before they cause permanent vision loss or chronic pain.

Elbow Dysplasia(ED)
Bewegungsapparat
Elbow dysplasia is a developmental disorder of the musculoskeletal system where the three bones forming the elbow joint do not fit together properly. This misalignment causes abnormal friction and wear on the joint cartilage, eventually leading to painful, chronic joint inflammation and arthritis. It is a complex genetic condition influenced by multiple genes.
Roentgen · Passing: 0
Merle coat pattern(M)
Haut und Fell
The merle coat pattern is caused by an autosomal-dominant mutation in the PMEL gene, which affects pigment-producing cells in the skin, eyes, and inner ears. When a dog inherits two copies of this gene, a condition known as double merle, it disrupts the normal development of these sensory organs. This genetic defect can lead to severe structural abnormalities in both the auditory and visual systems.
Passing: Genotyp-Bestimmung
Degenerative Myelopathy(DM)
Nervensystem
Degenerative Myelopathy is a progressive disease of the spinal cord where the protective sheath around the nerves slowly breaks down. This deterioration disrupts the vital communication signals between the brain and the muscles of the hind limbs. Over time, this lack of signal transmission leads to a complete loss of muscle control in the back legs.
DNA · Passing: CARRIER
Hyperuricosuria(HUU)
Nieren
Hyperuricosuria is an inherited metabolic disorder affecting the renal system, specifically how the kidneys process uric acid. Due to a genetic mutation, excess uric acid is excreted into the urine rather than being broken down. This high concentration can cause the acid to crystallize, leading to the formation of painful bladder or kidney stones, also known as uroliths.
