Formulated with a board-certified veterinary cardiologist

CardioChew was developed with the input of Dr. Matthew Miller, DVM, MS, DACVIM (Cardiology), a board-certified veterinary cardiologist with more than 30 years in canine heart care, including 26 years on the faculty of Texas A&M’s College of Veterinary Medicine. He helped choose every ingredient for its role in supporting normal heart and circulatory function.

Advanced Nutrient Blend

Each soft chew contains a powerful mix of key nutrients that help maintain normal cardiovascular and circulatory health:

  • L-Carnitine – Supports normal energy metabolism in cardiac muscle.

  • L-Taurine – Important for maintaining healthy heart and cellular function.

  • L-Arginine – Helps maintain normal vascular tone and blood flow.

  • Green Lipped Mussel Oil – Natural source of omega fatty acids and beneficial lipids.

  • Coenzyme Q10 – A naturally occurring antioxidant that supports normal energy production in heart cells and helps defend against oxidative stress.

Tasty and Easy to Give

Dogs love the natural bacon flavor — making it easy to include heart support in their daily routine. No pills, no powders, just feed the appropriate number of soft chews to your dog or alternatively break them and add them to your dog’s food in the morning and at night.
