Salt in the diet of dogs and cats is a topic that is often treated in an overly simplistic way. Some believe it should be avoided completely, while others add it without much thought to home-cooked diets, treats, or everyday meals.
In reality, however, the answer is not simply “yes” or “no”. It is: how much, for which animal, in which diet, and with what clinical objective.
Sodium, which is a key component of salt, is not inherently “bad”. It is an essential nutrient involved in fluid balance, nerve and muscle function, and electrolyte regulation. Therefore, the goal is not zero sodium intake, but a properly calculated sodium intake.
In complete commercial pet foods, sodium content should be assessed according to official nutritional standards, such as the European FEDIAF guidelines for complete dog and cat foods. These recommendations are not just about what appears on a label, but whether the food is complete, which life stage it is intended for, and how its sodium content compares on a dry matter basis or per 1000 kcal of metabolizable energy.

For adult dogs, the minimum recommended sodium levels in complete foods are approximately 0.25–0.29 g per 1000 kcal, while requirements are higher during growth and reproduction. For adult cats, the corresponding values are approximately 0.19–0.25 g per 1000 kcal, with increased needs also during growth and reproduction. This highlights a very important point: nutritional requirements are not the same for every animal, and we should not mechanically apply “dog rules” to cats, or vice versa. (europeanpetfood.org)
At the same time, the upper level considered safe for healthy dogs and cats should not be interpreted as a feeding target. FEDIAF reports safety data for sodium levels of up to 1.5% on a dry matter basis, or 3.75 g per 1000 kcal, in healthy animals. However, this does not mean that “more is better”. It simply means that, in healthy animals, these levels have been evaluated as safe based on the available data. (europeanpetfood.org)
In home-cooked diets, the issue becomes even more important. Salt should not be added “by eye”. A homemade recipe may be too low in sodium, excessive in sodium, or overall nutritionally unbalanced if it has not been properly formulated. The classic approach of “chicken, rice, and a little salt” is not clinical nutrition. It may be a temporary practical option in specific situations, but it cannot be considered a complete and individualized nutritional plan.
Particular care is needed in animals with chronic kidney disease, systemic hypertension, heart disease, or heart failure, as well as in animals receiving therapeutic diets or medication. In these cases, sodium is not just a minor dietary detail. It is part of the overall therapeutic plan. The international IRIS nephrology guidelines, for example, consider sodium in the context of managing animals with chronic kidney disease and hypertension, not as an isolated element but as part of a broader strategy.
At NutriVets, we do not view salt as something automatically forbidden or automatically harmless. We assess it within the overall nutritional and clinical context of each animal: species, age, diet, medical history, medication, laboratory results, and the true goal of the nutritional intervention.
Proper nutrition is not based on generic rules. It is based on assessment, calculation, individualization, and monitoring.
Book your appointment with NutriVets and design an individualized nutritional plan for your dog or cat, based on your pet’s real needs — not just general guidelines.
