Sodium – Villain or Superhero?
Sodium seems to be the culprit, sure. We Humans develop Sodium- related High Blood Pressure (or Hypertension) – but what about our Humanimals?
Actually this rarely seems to be the case for our dogs.
A related study says Hypertension isn’t a problem for dogs – although their kidneys may come under pressure. Healthy dogs are usually able to excrete excess sodium in their urine.
So when is there a real need for Low-Sodium Dog Food? And what should we be looking for?

Sodium Packs a Punch!
Hey, we all need Sodium as an essential nutrient for life.
After all, Sodium is a necessary mineral for:
- Regulation of blood pressure
- Acid/base balance
- Electrolyte balance
- To transmit impulses in the nerves, muscles, cells, and brain.
Sodium deficiency can actually be a serious problem.
It is important to ensure that the dry food comes with at least 0.3% of Sodium – this is the minimum recommended level recommended by the American Association of Feed Control (AAFC).
Natural sources of Sodium include:
- Red meat
Sodium is usually added to commercial dog food in the form of Table Salt, as a flavour enhancer. For most dogs, this isn’t a problem unless health issues are present.
The “Baddie” Exposed – Will Salt Kill my Dog?
Overdosing on Salt is toxic for dogs.
High levels of Sodium in a dog’s blood are linked to the condition known as Hypernatremia.
This condition is seen in a major loss of water through the gastrointestinal tract. This results in high blood pressure and increased risk of heart disease.
- Extreme urination
- Too much or too little water intake
Notify your vet immediately. Treatment usually involves fluid therapy, and the recommendation of a Low-Sodium diet.
Why go with the “Caped Crusader” Low Sodium?
Health Problems Needing A Low Sodium Diet
Congestive Heart Failure
This can be the result of a congenital defect, or even from parasites such as heartworms. It can also be due to a bad diet or lack of exercise.
Congestive Heart Failure causes fluid build up in the body, and Salt makes this worse.
It’s also harder for them to process Sodium ions.
- Difficulty breathing
- Decreased energy levels
Have him checked out at the vet promptly.
This may be the result of congenital defects, infectious diseases such as Hepatitis, or endocrine disorders such as Diabetes.
Liver problems from poisons:
See your vet immediately. Treatment depends on the cause, eg diuretics or enemas to flush the toxins from the system. Recovery from both the acute problems and from chronic failure can include a diet low in Sodium and protein.
This can come with old age or genetics. Kidney problems can be diet-related, or the result of poisoning.
Salt makes us thirsty! And our dogs too.
Sodium will build up water retention. Excessive water can lead to high blood pressure and increase the stress on already strained kidneys.
- Change in your dog’s water consumption or urination
- Weight loss
Consult your vet. A good renal diet will have less Sodium. The amount of protein should also be lower than usual, as higher amounts increase the stress on his organs.
So Who are the Victims of the Villain High Sodium?
Often it’s Senior Dogs.
Osteoporosis is very common for senior dogs and reducing salt intake can assist with muscle strength.
If your dog is a senior or if it has organ issues, Sodium makes a major difference – we may need to monitor their food. This may also be the case for dogs with poor nerve or muscle function.
A Serious Consideration
If your dog has:
- Started to gain weight?
- Been diagnosed with a severe heart, kidney, or liver condition?
In consultation with your vet, changing his diet may include an essential transition to a low-sodium regime.
What is the Optimal Daily Allowance for a Low- Sodium Diet?
The American Association of Feed Control (AAFC) don’t give a maximum acceptable quantity of Sodium. Neither do Dog Food manufacturers!
The National Research Council of the National Academies suggests a recommended maximum allowance of 200mg Sodium per day.
How to measure Sodium yourself:
Look at each 100kCal/ Calories as a unit of measurement.
Always consider the following in consultation with your vet.
Vermont Vetinary Cardiology recommends:
- No Sodium restriction: 0.5% Sodium (>100mg/100kCal)
- Mild Sodium restriction: 0.35% – 0.5% Sodium (80 – 100mg/100kCal)
- Moderate Sodium restriction: 0.1% – 0.35% Sodium (50 – 80mg/100kCal)
- Marked Sodium restriction: 0.15% – 0.2% Sodium (40 – 50 mg/100kCal)
- Extreme Sodium restriction: 0.075%-0.15% Sodium (20 – 40 mg/100kCal)
Look! Is it a Bird? A Plane? No! It’s Low Sodium Dog Food!
–What to Look for in Low-Sodium Dog Foods–
A balanced amount of protein in the diet benefits muscle tone, skin and coat quality.
By-products are all heavily processed, with who-knows-what in them! A scary thought. Generic meat-meals may also cause allergic reactions.
Healthy natural fats contain Omega fatty acids, essential for a dog’s skin and fur.
Whole grains provide more fiber. Slow-burning energy will avoid unhealthy blood sugar spikes.
To provide your dog with daily energy, it’s best to go for nutritious carbs:
- Brown rice
Look for foods rich in antioxidants like colorful fruits and vegetables.
Before you jump into a grain-free diet
Check out recent reports from the FDA about Grain-Free diets causing possible heart problems in dogs. This is apparently due to the replacement of grains with lots of potatoes, peas, beans or lentils.
Baddie Foods (on the “Wanted” list)
Monosodium Glutamate is a Sodium Salt used for flavor and as a preservative. This Baddie is especially found lurking in cheap, heavily processed food and treats. It has been known to cause serious symptoms in dogs.
Nitrates are used to preserve many meat items, eg ham, bacon, deli meats, and hot dogs.
Sodium Nitrate is an FDA – approved preservative. When it exceeds 8 mg/kg, it can cause Methemoglobin, a canine blood disorder. This Baddie may also increase the chance of cancer.
Tempting as it may be…
Don’t share your chips with your dog!! Same goes for those pickles. And put away that pizza! Keep it for your breakfast.
A big source of Sodium is human food.
All those handy Dog Treats might have to be watched for Sodium content.
Watch out for color, preservatives and flavor additives. They make your kids spin out, it’s the same for your dog!
