East Texas Vet Explains Pet Vitamin Deficiencies and Supplement Safety

Dr. Tammy Wilson of Flint Veterinary Clinic says most dogs and cats eating balanced commercial diets receive the vitamins and minerals they need, but deficiencies can occur with improperly formulated homemade or vegetarian diets. Common problems include deficiencies in vitamins A, B, and D, calcium, phosphorus, and taurine. Nutrient deficiencies can contribute to poor growth, skin and coat problems, digestive issues, lethargy, anemia, weak bones, fractures, and even heart failure.

Young animals, seniors, and pets with chronic illnesses may have different nutritional requirements. Wilson recommends consulting a veterinarian or Veterinary nutritionist before adding supplements, particularly for pets with medical conditions. Supplements such as fish oil, joint products, vitamin E, and antioxidants can be beneficial when appropriately used, but excessive supplementation can also cause health problems. Vitamin D3 overdose is particularly dangerous and can cause tissue mineralization and kidney failure. Wilson recommends feeding primarily balanced pet food and verifying nutrition and supplement decisions with a veterinarian.
