Canine and Feline Lymphosarcoma
Lymphosarcoma is a malignant cancer of the lymph nodes and lymphoid tissue that affects both dogs and cats, most often dogs over four years of age. It presents in multicentric, alimentary, and thymic forms, each with distinct clinical signs. While incurable, prompt chemotherapy can extend life from a matter of weeks to 6–24 months.
Canine and Feline Lymphosarcoma (Lymphoma)
Lymphosarcoma, also called lymphoma, is a malignant tumor of lymphocytes that arises in lymph nodes or other lymphoid tissue. It occurs in both dogs and cats, more often in dogs over about 4 years, and appears as multicentric, alimentary, or thymic forms with enlargement of lymph nodes, digestive upset, or chest masses.
Canine and Feline Spinal Cord Tumors
Spinal cord tumors in dogs and cats produce signs based on where they compress the cord, ranging from limb weakness to paralysis and loss of bladder control. German Shepherds and young to middle-aged dogs are commonly affected, with tumors often located between the 10th thoracic and 3rd lumbar vertebrae.
Canine and Feline Brain Tumors
Brain tumors in dogs and cats are most often meningeal or glial tumors that appear in middle-aged to older pets, with some breeds such as Boxers and Bulldogs overrepresented. They compress brain tissue and cause gradually worsening neurological signs including behavior changes, circling, head tilt, blindness, and seizures.
Canine and Feline Hemangioma and Hemangiosarcoma
Hemangiomas are slow-growing benign tumors of blood vessels, while hemangiosarcomas are aggressive malignant vascular tumors that often spread before signs appear. Common sites include the skin, spleen, liver, heart, and bone, with large breeds such as Great Danes, Boxers, and German Shepherds overrepresented.
Multiple Myeloma in Dogs and Cats
Multiple myeloma is a malignant plasma-cell tumor of the bone marrow that overproduces immunoglobulin and is rare in dogs and cats. Signs include lameness, bone pain, anemia, bleeding, and weakness, with diagnosis by X-rays, bloodwork, and marrow sampling. Treatment is chemotherapy plus infection control.
Sertoli Cell Tumors in Dogs and Cats
Sertoli cell tumors are hormone-producing testicular tumors of older male dogs and cats that cause feminization through excess estrogen. Signs include symmetrical hair loss, enlarged breasts, and a lengthened prepuce. Surgical removal of both testicles resolves most signs within a few months.
Canine and Feline Gammopathy (Dysgammaglobulinemia)
Gammopathy is an abnormal rise in blood immunoglobulins, usually from cancer or chronic disease, which can damage organs and bones. Treatment targets the underlying cause, especially any tumor.
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.
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.
