What Is Canine Hemangiosarcoma
Hemangiosarcoma is a malignant tumor that arises from the cells lining a dog's blood vessels. It grows fast, invades deeply, and often spreads to the lungs and liver before it is noticed. Middle-aged and older dogs are most at risk, with some breeds more prone than others. Knowing the signs and the guarded prognosis helps owners make timely decisions.
What Is Storage Disease in Dogs?
Storage disease is a hereditary metabolic disorder where certain substances build up abnormally in the body's tissues. The two most reported forms in veterinary medicine are lysosomal storage disease and glycogen storage disease. It strikes dogs and cats, is very rare, and appears early in puppies and kittens because it is inherited. Nerve-related signs include poor growth, ataxia, seizures, exercise intolerance, behavior changes, and vision loss. Diagnosis uses blood, urine, imaging, biopsy, and enzyme tests; care is supportive, and affected dogs should never be bred.
Why Pets Drool: Stomatitis and Periodontal Disease
Persistent drooling often points to mouth inflammation. Stomatitis can be contagious (virus-linked) and, in cats, often lifelong — a red line forms where gum meets tooth, with constant drooling. As it worsens, ulcers grow, the cat may stop eating and lose weight. Periodontitis, driven by bacteria and tartar, also causes drooling, bad breath, and tooth loss. Diagnosis needs an oral exam (often under anesthesia) and dental X-rays; treatment ranges from antibacterial rinses to antibiotics and, in severe tartar cases, extraction.
My dog’s belly is very swollen, hind legs are weak and hard-swollen, with black diarrhea — what tests should I get?
Abdominal enlargement with hind-leg swelling usually needs ultrasound, imaging, and possibly a tissue biopsy. See a vet; the clinician will select the right tests based on symptoms. With many signs present, a thorough workup is needed to find the cause.
Cat Has Chronic Diarrhea? It’s More Than a Sensitive Stomach
Long-term diarrhea in cats is rarely just a 'delicate stomach' you can fix by swapping food or adding probiotics. Diet and food allergy are common, but so are parasites (some needing specific drugs), inflammatory bowel disease, and metabolic diseases like pancreatitis, hyperthyroidism, or kidney disease. Stress is a third driver. Work through the causes step by step and let a vet run the right tests.
Why Does My Cat Still Itch After Deworming?
A cat that keeps scratching after a dewormer isn't necessarily proof the product failed. Dewormers kill parasites but not skin problems, and the wrong product, wrong application, or an untreated home can all leave itching in place. Flea-allergy dermatitis, mites, dry skin, and stress can itch too. Mild scratching for a day or two may just need patience; anything longer with skin damage needs a vet.
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 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.
Leiomyomas in Dogs and Cats
Leiomyomas are benign smooth-muscle tumors that can arise wherever smooth muscle exists, such as the uterus, stomach, intestine, and blood-vessel walls. Dogs are affected more often than cats. Surgical removal is the usual treatment, and follow-up care prevents spread.
