Pet Supplements 101: Understanding the Basics
Pet supplements are products intended to complement the diet and provide nutrients that may be lacking or needed in higher amounts due to specific health conditions, life stages, or environmental factors. Unlike medications, supplements are not intended to treat, diagnose, prevent, or cure diseases.
Key Distinction
Supplements should complement a balanced diet, not replace proper nutrition. Always prioritize feeding a complete and balanced commercial or veterinary-recommended diet before considering supplements. For comprehensive nutrition information, see our dog food quality guide.
