Hepatic Encephalopathy in Dogs and Cats
Hepatic encephalopathy is a neurological syndrome in dogs and cats caused by liver dysfunction that allows toxic metabolites such as ammonia to reach the brain. It produces recurring signs ranging from lethargy and ataxia to seizures, circling, and coma, and is often triggered by high-protein meals, gastrointestinal bleeding, or dehydration.
Epilepsy in Dogs and Cats: Symptoms, Treatment, and Prevention
Epilepsy is recurrent seizure activity from sudden abnormal electrical discharges in the brain, either inherited (primary) or caused by underlying disease (secondary). It brings brief loss of consciousness and convulsions, and is managed with anti-seizure medication and trigger avoidance.
Meningoencephalitis in Dogs and Cats: Symptoms, Treatment, and Prevention
Meningoencephalitis is inflammation of the brain and its membranes from infection, toxins, immune disease, trauma, or tumors, producing seizures, behavior change, and stiffness. Treatment targets the cause with infection control, swelling reduction, and seizure management.
Polycythemia in Dogs and Cats: Symptoms, Treatment, and Prevention
Polycythemia is an increase in red-blood-cell concentration, either from fluid loss or from true overproduction by the marrow. Thickened blood can cause oxygen shortage, seizures, and clots, and treatment restores normal volume or reduces cell mass under veterinary care.
Anemia in Dogs and Cats: Symptoms, Treatment, and Prevention
Anemia is not a disease itself but a sign of many conditions in which red cells or hemoglobin fall short, depriving tissues of oxygen. Pets become weak, pale, and breathless, and treatment corrects the underlying cause while rebuilding red cells through diet, supplements, or transfusion.
Disseminated Intravascular Coagulation (DIC) in Dogs and Cats: Symptoms, Treatment, and Prevention
Disseminated intravascular coagulation (DIC) is a body-wide clotting crisis triggered by severe illness, poisoning, or immune failure, in which clots form and consume factors, then bleeding begins. It is a medical emergency treated by resolving the underlying disease plus transfusion and anticoagulation.
Myocarditis in Dogs and Cats: Symptoms, Treatment, and Prevention
Myocarditis is inflammation of the heart muscle, usually secondary to infection, parasites, toxins, or metabolic disease. It raises myocardial excitability and weakens contraction, and severe cases can cause collapse or sudden death, so prompt veterinary care is essential.
Dilated Cardiomyopathy in Dogs and Cats: Symptoms, Treatment, and Prevention
Dilated cardiomyopathy (DCM) is a heart-muscle disorder in which the ventricular chambers enlarge and weaken, leading to poor pumping, congestive heart failure, and arrhythmias. Large and middle-sized breeds are most at risk, and signs include weakness, coughing, abdominal swelling, and fainting.
Sinus Tachycardia and Bradycardia in Dogs and Cats
Sinus tachycardia is a faster-than-normal but regular heart rhythm, common in newborn puppies and kittens and usually harmless on its own. Sinus bradycardia is a slow rhythm from hypothyroidism, toxicity, or low potassium. Both are managed by treating the underlying cause.
Heart Failure in Dogs and Cats
Heart failure is the syndrome in which a weakened heart cannot pump enough blood, causing congestion and poor tissue supply. It may follow severe infection, toxicity, kidney disease, or sudden exertion, and shows as breathlessness, weakness, and fluid buildup. Treatment eases the heart's workload and supports circulation.
