Salt is an important component of your dog's diet and has a crucial role to play in his well being. Salt (or sodium chloride) maintains bodily fluids and is needed for the functioning of organs and nervous system.
Salt can be added to products to improve their taste.
Excessive salt intake may lead to increased blood pressure and aggravate the signs of heart disease. Also, most dogs with kidney disease already suffer from hypertension. Particularly when dogs are older these conditions may already be present without owners being aware of it.
However, since great taste can be achieved without unnecessarily high salt levels, we at Hill's® strictly control the salt content of our food, without compromising on the taste or its nutritional value. It's just that we know that dogs at different life stages and with specific nutritional needs require food that has just the right balance of vitamins, minerals and high quality ingredients.
So with Hill's® Science Diet®, you can be sure that your dog is getting just the right balance of nutrients without the risks associated with excess salt. And what's more he'll love the taste - guaranteed.
