• Collie eye anomaly (CEA)(CEA)

  Augen

  Collie Eye Anomaly is an inherited developmental defect affecting the eye, specifically the retina (the light-sensitive tissue at the back of the eye) and the choroid (the underlying layer of blood vessels). This genetic condition causes these structures to develop abnormally before birth. It is primarily seen in herding breeds and is inherited in an autosomal recessive manner.

• 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.

• Cataract(HC)

  Augen und Sehvermögen

  A cataract is a progressive clouding of the lens inside the dog's eye, which is the clear structure that focuses light onto the retina at the back of the eye. When the lens becomes cloudy or opaque, it blocks light from entering, gradually impairing the dog's vision. If left untreated, this condition can eventually lead to complete blindness in the affected eye.

• Exercise Induced Collapse(EIC)

  Bewegungsapparat

  Exercise Induced Collapse (EIC) is an inherited disorder of the nervous system where the communication between the brain and the muscles temporarily breaks down during intense physical activity or high excitement. This neurological failure prevents the muscles from receiving the signals they need to function properly, causing a sudden loss of motor control. It is inherited in an autosomal-recessive manner, meaning a dog must inherit the mutated gene from both parents to be affected.

• Hereditary myopathy - Labrador retriever/Bouviers des Flandres myopathy(CNM)

  Bewegungsapparat

  This is an inherited muscle disease affecting the skeletal muscles of Labrador Retrievers and Bouviers des Flandres. It is caused by a genetic defect that prevents muscle fibers from developing normally, leading to progressive muscle wasting where the muscles gradually shrink and weaken.

• Hip dysplasia(HD)

  Bewegungsapparat

  Hip dysplasia is an inherited skeletal disorder where the ball and socket of the hip joint do not fit together properly. Instead of sliding smoothly, the bones rub and grind against each other, wearing down the protective cartilage. Over time, this chronic friction causes joint instability, painful inflammation, and progressive arthritis, which is the gradual wear and tear of the joint.

• 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.

• MDR1 gene mutation (drug sensitivity)(MDR1)

  Nervensystem

  This genetic condition affects the nervous system by impairing the blood-brain barrier, which normally acts as a protective filter for the brain. Due to a missing transport protein, certain common medications can cross this barrier unchecked and accumulate in the brain. This can lead to severe, life-threatening neurological damage.
