Patent ductus arteriosus is a congenital cardiac defect in which the fetal ductus arteriosus fails to close after birth, allowing abnormal blood flow from the aorta to the pulmonary artery and causing volume overload of the left side of the heart.
Cardiac disease is a broad category of structural, functional, congenital, acquired, electrical, or degenerative disorders that impair normal heart performance and may lead to murmurs, arrhythmias, poor circulation, exercise intolerance, or congestive heart failure.
Ectropion is outward rolling or drooping of the eyelid margin, most often the lower lid, causing conjunctival exposure, poor tear distribution, irritation, discharge, and recurrent conjunctivitis or corneal exposure problems.
Von Willebrand disease is an inherited bleeding disorder caused by quantitative or qualitative deficiency of von Willebrand factor, impairing platelet adhesion and primary hemostasis and causing prolonged or excessive bleeding.
Congenital heart disease is any structural or functional cardiac abnormality present at birth, including defects of valves, outflow tracts, septa, great vessels, or other components of cardiac development.
Keratoconjunctivitis sicca is tear film deficiency, usually from reduced aqueous tear production, causing dryness and inflammation of the cornea and conjunctiva with risk of corneal ulceration, pigmentation, scarring, and vision loss.
Dilated cardiomyopathy is myocardial disease characterized by ventricular dilation and impaired systolic contraction, leading to reduced cardiac output, arrhythmias, congestive heart failure, collapse, or sudden death.
Exercise-induced collapse is an inherited neuromuscular syndrome associated with DNM1 variants in which affected dogs develop episodic weakness, incoordination, or collapse after intense exercise or excitement while appearing normal at rest.
A cataract is an opacity of the crystalline lens or its capsule that interferes with transmission of light to the retina and may impair vision depending on size, location, maturity, and underlying cause.
Hereditary cataracts are genetically influenced lens opacities that occur independently of trauma, diabetes, or age-related change and may appear in juvenile, adult-onset, progressive, or breed-specific patterns.
