What’s Up With Sodium in Your Dog’s Diet?

Why Is Sodium Necessary?

Low Sodium Foods For Dogs

Just like we do, dogs need a certain amount of sodium in their diet. It is an electrolyte like potassium and chloride.

The mineral is necessary for their body to run optimally. It plays a vital role in the functioning of your pet’s muscles and nerves.

Significantly, it is crucial in maintaining the balance of water in a dog’s body.

Sodium is present in all their cells. It stops them from dehydrating and keeps them swollen so that they can keep on working.

Recommended Sodium Intake for Your Dog

You should remember that different dogs have different dietary and nutritional requirements.

According to AAFCO, the bare minimum amount of sodium that an adult dog needs is 0.06% of their diet. Their recommended minimum is 20 mg per 100 kcal.

The mineral needs to make up at least 0.3% of growing or pregnant dogs diet.

A responsible pet owner should always be wary. Unfortunately, most pet foods contain much more sodium than your dog needs.

Usually, this won’t be an issue because dogs would excrete the excess minerals in their urine.

But there are various conditions which can be worsened and even be caused by the consumption of high amounts of sodium. 

In these cases, you should attempt to reduce the sodium your dog eats.

Note that it isn’t recommended that any dog eat food that contains more than 100 milligrams per kilocalorie.

When Is a Low Sodium Diet Necessary?

Research has shown that your dog can benefit from a diet with sodium restrictions if they suffer from the following health issues:

  • Your pet has renal disease.
  • A dog has kidney damage.
  • The canine struggles with hypertension, in other words, high blood pressure.
  • Your dog has a cardiac condition like Congestive Heart Failure (CHF).

Regularly feeding them food that is low in sodium can help you to manage these concerns and to safeguard their health.

There are different levels of restrictions:

  • Mild restrictive diets contain 80-100 mg of Sodium per 100 kcal.
  • Moderate restrictive diets contain 50-80 mg of Sodium per 100 kcal.
  • Severe restrictive diets contain less than 50 mg of Sodium per 100 kcal

There is a significant variance in the mineral content of products.

The sodium level that your pet should eat depends on the severity of their health issues, for instance, a dog with heart failure needs to eat food with severely reduced sodium levels.

The products on the list fall under the moderate and severe restrictions. In contrast to this average commercial dog foods contain more or less 100 mg kcal of sodium.

You can check the nutritional content of a portion of food by reading its ingredients and nutrient analysis carefully. 

Treats can also pack quite a lot of minerals and nutrients, so you need to factor this into your dog’s daily diet.

If you decide to opt for a low sodium dog food be wary that you don’t feed them too little sodium.

You don’t want your pet to develop a deficiency.

Remember that you should always consult your veterinarian if your pet is ill. They will be able to advise you on the right course of action.

You can ask them which product they recommend for your furry friend.
