The Value of Low Sodium Dog Food

How to choose the best Low Sodium Dog Food?

If your furry friend has congestive heart failure, kidney disease, hypernatremia, or heart disease, then they need a low sodium diet. However, choosing the right low sodium dog food isn’t an easy task. It requires research.

Firstly, you should consult your vet. Your pup might have other problems, such as allergies, that you need to consider when choosing the type and brand of food. Furthermore, don’t forget that taking in too little sodium can be as harmful as excessive amounts.

​What are the benefits of low sodium dog food?

The primary benefit is reducing risk and treating heart diseases. Furthermore, a low-sodium diet will regulate the water intake. If your dog’s food is too salty, they will drink a lot of water. That can cause problems with kidneys and also damage the circulation system.

Moreover, low levels of sodium will keep your dog better hydrated.

Should all dogs have a low sodium diet?

Some people hear that sodium is bad for their furry friends and cut it out of their diets entirely. However, that’s the wrong thing to do. Sodium is good for your pooch’s health. What’s more, a non-prescribed low-sodium diet can damage the health of your dog. Furthermore, sodium is vital for proper cell function and hydration. Therefore, by cutting it out of your dog’s diet, you are doing them a disservice.

And the winner is…

In our humble opinion, the Zignature Whitefish Formula takes the coveted number one spot of the low sodium dog food competition.

It’s the only choice on our list that doesn’t include common allergens. It is also grain-free. Therefore, it seems like a good choice even for the most sensitive and allergy-prone dogs. Not to mention, the main protein is the Whitefish, a healthy choice that has a lot of benefits.
