Buyer’s Guide: Choosing the Best Low-Sodium Dog Food
What’s the Benefit of a Low Sodium Diet?
If your dog is healthy and has no existing medical problems, then a low or reduced sodium dog food likely isn’t necessary for them. In fact, sodium is an essential nutrient that supports healthy cardiovascular function. Healthy dogs are able to efficiently process excess sodium through their body, but dogs with heart problems may not be able to.
Dogs with congestive heart failure (CHF) and other forms of heart disease, like cardiomyopathy, can often benefit from reduced sodium diets. This is because without proper cardiac function, they may not be able to properly process, use, and excrete sodium. This can lead to a buildup of sodium within the body, leading to worsening heart disease symptoms, like edema (fluid buildup) and high blood pressure.
Keep in mind that there are other specific nutrients that can be of concern for a dog with heart disease, like potassium, phosphorus, protein, and omega-3 fatty acids.
How Can I Choose a Low Sodium Diet for My Dog?
Although there are great foods here to help you find a starting point, you should always discuss dietary changes with your dog’s vet. This is of special importance if your dog has specific nutritional needs related to heart disease. Simply switching your dog to a reduced sodium diet is likely not going to be the only change that will need to be made.
Taking a list of foods you think your dog might be interested in and that fit in your budget can be a great way to help your vet help you better select a food to meet your needs.
