Dogs with heart disease including cardiac insufficiency need a special diet as well as very special care. Low appetite is a particular problem for dogs with heart disease and that can lead to weight loss. Royal Canin Veterinary diet â Cardiac is a veterinary food that works to combat oxidative metabolic reactions, whilst at the same time supporting tissue perfusion and vasodilation. Dogs with heart disease also have a higher risk of developing chronic renal insufficiency (CNI). Using a food with a low phosphorus content can help to prevent this at an early stage. This dry kibble also has a reduced sodium, potassium and magnesium content, to ease the strain on the heart, whilst added L-carnitine and taurine promote healthy heart muscle. Recommended for (indications): High blood pressure Cardiac insufficiency Not recommended for (contraindications): Pancreatitis Hyperlipidemia Hyponatremia Puppies Pregnant or lactating bitches Key benefits: Supports blood vessels: Flavonoids (especially polyphenols) play a key role in fighting oxidative metabolic reactions whilst also supporting tissue perfusion and vasodilation. Early support of kidney function: Low phosphorus content can help to prevent chronic renal insufficiency (CNI), which often occurs in parallel with heart disease. Electrolyte balance: Low levels of sodium, potassium and magnesium all help to reduce the strain on the heart. High L-Carnitin and taurine levels: Taurine and l-carnitine are important for the function of myozytes and help the heart muscles (contraction). Duration of treatment: The dietetic treatment of dogs with heart disease should start as soon as the first symptoms of heart disease are noted. This food can be used indefinitely, in consultation with your vet.
