Vitamin A Toxicity (Hypervitaminosis A) in Dogs and Cats
Vitamin A toxicity in dogs and cats follows prolonged over-supplementation with vitamin A or liver-heavy diets, suppressing bone-forming cells and causing periosteal bone spurs, pain, and lameness. It is reversed by stopping excess vitamin A and providing supportive joint care.
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.
What Happens When a Cat Lacks Vitamin C
Long-term lack of vitamin C gives a cat scurvy: low spirit, poor appetite, anemia, weight loss and easy bleeding or skin inflammation. As it worsens, gums swell and bleed, wounds heal poorly, and in severe cases cheeks and tongue ulcerate or die back, with joint pain and bleeding in the bladder, gut, kidney or nose. Treat with oral or injected vitamin C plus symptomatic care, and prevent it with a balanced, complete diet, since processing destroys much of the vitamin in food.
Niacin (Vitamin B3) Deficiency in Dogs and Cats
Niacin (vitamin B3) deficiency in dogs and cats causes pellagra-like signs, oral and esophageal ulcers, black tongue in dogs, diarrhea, anemia, and symmetric dermatitis. It follows corn-heavy diets low in tryptophan, and is corrected with dietary niacin.
Biotin (Vitamin H) Deficiency in Dogs and Cats
Biotin (vitamin H) deficiency in dogs and cats causes scaly dermatitis, hair loss, poor growth, and later weakness, diarrhea, and hind-limb paralysis. It is usually due to raw-egg white (avidin) or gut flora imbalance, and is corrected with dietary biotin.
Vitamin K Deficiency in Dogs and Cats
Vitamin K deficiency in dogs and cats impairs clotting-factor synthesis, causing prolonged bleeding time, subcutaneous and body-cavity hemorrhage, and anemia. It arises from malabsorption, long-term antibiotics, or certain poisons, and is treated with vitamin K and management of the underlying cause.
Vitamin E Deficiency in Dogs and Cats
Vitamin E deficiency in dogs and cats, often with selenium lack, causes skeletal muscle degeneration, reproductive failure, and in cats cerebellar ataxia, plus a fat-tissue inflammation known as yellow fat disease. It is corrected with dietary vitamin E and treatment of any gut disease.
Vitamin D Deficiency in Dogs and Cats
Vitamin D deficiency in dogs and cats impairs calcium and phosphorus use, leading to rickets in the young and osteomalacia in adults, with bone pain, lameness, and deformities. It is prevented and treated by correcting diet, ensuring sunlight, and veterinary-directed vitamin D and calcium.
Vitamin C (Ascorbic Acid) Deficiency in Dogs and Cats
Vitamin C deficiency in dogs and cats weakens connective tissue and capillary walls, causing easy bleeding, gum disease, slow wound healing, and in growing animals painful swollen limb ends and lameness (scurvy). It is corrected by adding vitamin C-rich foods and treating any underlying illness.
Vitamin B6 (Pyridoxine) Deficiency in Dogs and Cats
Vitamin B6 (pyridoxine) deficiency in dogs and cats impairs hemoglobin synthesis and nerve function, causing microcytic hypochromic anemia, poor appetite, skin inflammation, and seizures or ataxia. It is corrected with pyridoxine and a balanced diet.
