Cellulitis in Dogs and Cats
Cellulitis is a rapidly spreading infection of the soft tissue under the skin, usually from pus-forming bacteria. It causes hot, painful swelling and fever, and can progress to abscess or sepsis if untreated. Combined local and whole-body care stops spread.
Thiamine (Vitamin B1) Deficiency in Dogs and Cats
Thiamine (vitamin B1) deficiency in dogs and cats impairs glucose metabolism and especially nerve function, producing anorexia, weakness, and progressive neurological signs such as ataxia, seizures, and paralysis. It is caused by raw-fish diets, gut or liver disease, and high demand, and responds to thiamine replacement.
Vitamin A Deficiency in Dogs and Cats
Vitamin A deficiency in dogs and cats results from a diet lacking preformed vitamin A and its precursors, impairing vision, skin, growth, and reproduction. It causes night blindness, dry eye, flaky skin, and in young animals bone deformity and paralysis, and is corrected by dietary vitamin A and treating any gut disease.
Lactose Intolerance in Dogs and Cats
Lactose intolerance in dogs and cats is the inability to digest lactose in milk and dairy products because of low lactase activity in the intestinal lining. It causes osmotic diarrhea, abdominal discomfort, and a gurgling abdomen after dairy is consumed, and resolves simply by removing dairy from the diet.
Transient Hypoglycemia in Puppies
Transient hypoglycemia is low blood sugar in young puppies, especially small breeds, from poor reserves or cold and hunger. It causes weakness, cries, and seizures, and is fixed by warming, feeding, and glucose.
Canine and Feline Immunodeficiency Disease
Immunodeficiency is a failure of the immune system, born or acquired, that leaves pets unable to fight infections, leading to repeated, hard-to-treat illness. Congenital forms cannot be cured, while acquired forms are managed supportively.
Myelitis and Meningomyelitis in Dogs and Cats
Myelitis and meningomyelitis are inflammations of the spinal cord and its surrounding membranes, often secondary to infection or trauma. They cause fever, pain, and progressive weakness or paralysis, and treatment must eliminate the underlying cause while controlling inflammation.
Heatstroke and Sunstroke in Dogs: Symptoms, Treatment, and Prevention
Heatstroke and sunstroke—together called heat illness—overwhelm a dog's ability to shed heat, sending body temperature dangerously high and damaging the brain and organs. Large and short-nosed breeds are most at risk, and rapid cooling with veterinary care is lifesaving.
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.
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.
