Canine and Feline Lymphosarcoma (Lymphoma)
Lymphosarcoma, or lymphoma, is a malignant lymphoid tumor in dogs and cats that appears as multicentric, alimentary, or thymic forms with lymph-node enlargement, diarrhea, or chest masses. Diagnosis uses aspirate, biopsy, and imaging, and veterinary-directed chemotherapy can extend life, though the disease is generally not curable.
Canine and Feline Hemangioma and Hemangiosarcoma
Hemangiomas are slow-growing benign blood-vessel tumors, while hemangiosarcomas are aggressive malignant vascular tumors of the skin, spleen, liver, heart, or bone. Diagnosis uses imaging and biopsy, and treatment may include surgery and veterinary-directed chemotherapy, though prognosis is often poor once spread occurs.
Multiple Myeloma in Dogs and Cats
Multiple myeloma is a rare malignant plasma-cell tumor of the bone marrow in dogs and cats that overproduces immunoglobulin, causing lameness, bone pain, anemia, bleeding, and weakness. Diagnosis uses X-rays, bloodwork, and marrow sampling, and treatment is chemotherapy with infection control.
When Your Dog Pants After a Short Walk: A Heart-Health Warning
Panting after brief exercise can be normal, but a formerly active dog that tires quickly, pants without exertion, coughs at night, or shows blue gums may have heart disease. Diagnosis uses auscultation, X-ray, and echocardiography, and early care with diet, gentle exercise, and veterinary-directed medication slows progression.
Shock in Dogs and Cats
Shock is acute circulatory failure that leaves vital organs starved of oxygen. It can follow severe disease, trauma, or poisoning, and shows as pale gums, weakness, cold extremities, and collapse. Treating the underlying cause is the foundation of recovery.
Ephedrine Poisoning in Dogs and Cats
Ephedrine poisoning happens when pets receive too much ephedrine-containing medication. It causes restlessness, trembling, drooling, vomiting, and dangerously fast heart and breathing rates. Stopping the drug and prompt veterinary care are essential.
Toad Poisoning in Dogs and Cats
Toad poisoning occurs when dogs or cats bite toads or lick toad eggs, skin secretions, or venom on wounds. Signs include heavy drooling, vomiting, irregular heartbeat, and seizures. Immediate flushing of the mouth and urgent veterinary treatment are critical.
Hyperthyroidism in Dogs and Cats
Hyperthyroidism is excess thyroid hormone from a thyroid tumor or hyperplasia that raises metabolism and nerve excitability. It causes weight loss with increased appetite, a fast or irregular heartbeat, and hyperactivity, and is managed with antithyroid drugs, radioactive iodine, or surgery.
Pericardial Effusion in Dogs and Cats: Symptoms, Treatment, and Prevention
Pericardial effusion is fluid buildup around the heart from failure, parasites, anemia, or tumors that compresses the heart. Drainage plus treatment of the cause is required; parasite prevention reduces risk.
Pericarditis in Dogs and Cats: Symptoms, Treatment, and Prevention
Pericarditis is inflammation of the heart sac, often from infection, tumors, rheumatism, or uremia, causing fever and fluid around the heart. It is treated with antibiotics, drainage, and tumor management; early infection control aids prevention.
