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.
Lymphangitis and Lymphadenitis in Dogs and Cats: Symptoms, Treatment, and Prevention
Lymphangitis and lymphadenitis are inflammations of the lymph vessels and nodes, usually from infection, immune disorders, or tumors. Signs vary by location but center on swelling, pain, and systemic inflammation, and treatment targets the underlying disease.
Feline Immunodeficiency Virus (FIV): Symptoms, Treatment, and Prevention
Feline Immunodeficiency Virus (FIV), often called 'feline AIDS,' is a chronic retroviral infection of cats first identified in 1987. It weakens the immune system so cats become vulnerable to secondary infections. Unlike human HIV, FIV is not sexually transmitted; it spreads mainly through bite wounds and shared saliva, and infected cats often live a normal lifespan. The virus does not infect humans.
How Lymphoma in Dogs Is Diagnosed
If lymphoma is suspected, the vet starts with a full history and physical exam, then adds tests to confirm lymphosarcoma and rule out other diseases. Fine-needle aspiration is the most common first step.
Cat Scratch Disease: A Zoonosis You Should Know
Cat scratch disease is a bacterial infection from Bartonella henselae, passed mainly by a cat's scratch or bite. Cats carry it without symptoms, but people can develop a red bump, swollen lymph nodes, and fever. Most cases are mild and self-limiting, yet antibiotics help when symptoms are strong. Wash any scratch well, and see a doctor if signs appear—especially for children and the immunocompromised.
Mammary Tumors in Dogs and Cats
Mammary tumors are common in intact female dogs and are the third most common feline tumor. They often appear as firm nodules in the mammary chain and can ulcerate or spread to lymph nodes and lungs. Early spaying sharply lowers risk, and surgery is the main treatment.
Prostatic Tumors in Dogs and Cats
Prostatic tumors occur mainly in middle-aged and older dogs and mimic benign prostatic conditions. Adenocarcinoma is the most serious type and can spread to local lymph nodes, spine, and pelvis. Signs include weight loss, thirst, back pain, and difficulty urinating.
Coccidioidomycosis in Dogs and Cats: Symptoms, Treatment, and Prevention
Coccidioidomycosis, also called coccidioidal granuloma, is caused by Coccidioides immitis. It usually presents as an acute, benign, asymptomatic, or self-limiting primary respiratory infection, occasionally disseminating to form focal lesions in skin, subcutaneous tissue, lymph nodes, bone, liver, kidney, meninges, brain, or other tissues.
Does Abdominal Fluid in Cats Always Mean FIP?
Fluid in a cat's abdomen, or ascites, is a sign—not a diagnosis. It can stem from liver or heart disease, kidney failure, malnutrition, or peritonitis caused by infection, viruses, or injury, and only one of those causes is feline infectious peritonitis (FIP). Because the symptom alone cannot confirm FIP, diagnosis needs bloodwork, imaging such as X-ray or ultrasound, and viral testing. If your cat shows a swollen belly, lethargy, fever, or breathing trouble, see a veterinarian promptly to find the real cause.
