best low phosphorus dog food

Here is my detailed guide to the best low phosphorus dog foods in 2021.

Kidney disease is a very common condition in dogs, especially the elderly. Diet cannot cure it, but an important part of treatment is choosing the right dog food. 

A low phosphorus diet can relieve stress on your dog’s kidneys, and this will greatly reduce the worsening of serious illnesses. 

I researched for over a day before I found the best low phosphorus dog foods on the market. Prescription and non-prescription products will also be on my list. 

Of the former group, my favorite is the Blue Buffalo Natural Veterinary Diet KS Kidney Support, and of the latter, Dr. Harvey’s Canine Health The Miracle Dog Food Pre-Mix

In addition to their low phosphorus content, I chose these products because of their exceptional quality. By the way, you will also find other useful information in my article.

Best Prescription Low Phosphorus Dog Foods

If your dog needs a low phosphorus diet, you should definitely check with your veterinarian. 

In some cases, experts recommend products that are subject to prescription. Pay attention because these diets are not always of the best quality. Although their phosphorus content is generally adequate, they may contain poor ingredients, such as meat by-product meals. 

I wanted to make your job easier, and I have collected the best prescription low phosphorus dog foods for you.

Blue Buffalo Natural Veterinary Diet KS Kidney Support

Key features:

  • The first 5 ingredients are Deboned Chicken, Potato Starch, Pea Starch, Peas, Potatoes
  • Controlled levels of protein
  • Also has controlled levels of phosphorus and sodium
  • Contains antioxidants, L-carnitine, and omega 3 fatty acids
  • Grain-free diet

Phosphorus level: 0.25%

Whatever your dog’s diet, Blue Buffalo is almost certain to have a suitable product. I love this brand because their products contain plenty of premium quality ingredients, with real meat in the first place. 

The other ingredients are usually digestible carbohydrates, healthy fats, fresh fruits, and vegetables. And a special blend called LifeSource Bits, developed by Blue Buffalo, adds the right amount of vitamins, minerals, and amino acids to recipes. 

Of the prescription diets, this product is the best possible because of the ingredients. 

The main source of protein is real chicken, which is an easily digestible low-fat meat with low phosphorus content. Besides, the product contains Dried Egg Product, which has excellent biological value. 

The recipe is grain-free and includes carbohydrate sources such as Potato Starch, Pea Starch, Peas, and Potatoes. They provide the energy you need and contain plenty of fiber and other useful nutrients. 

Sources of fat are Chicken Fat, Flaxseed, and Fish Oil. They add a well-balanced omega fatty acid profile to your diet. 

Omega-3 fatty acids are known to positively affect various inflammations, dog skin and coat, and overall health. Because of this, they are included in many low phosphorus diets. 

In this recipe for Blue Buffalo, protein and mineral levels are properly regulated. This gives maximum support to the work of the kidneys. 

If your veterinarian recommends a prescription diet for your dog with some kidney problem, consider the Blue Buffalo Natural Veterinary Diet KS Kidney Support first. It’s also available in a canned wet form


Royal Canin Veterinary Diet Hydrolyzed Protein Moderate Calorie

Key features:

  • The first 5 ingredients are Brewers Rice, Hydrolyzed Soy Protein, Chicken Fat, Natural Flavors, Dried Plain Beet Pulp
  • Suitable for dogs with food sensitivities and skin, coat, and digestive issues
  • Moderate fat and calorie content
  • Great for dogs with kidney problems
  • Contains fibers, prebiotics, B vitamins, amino acids, and omega-3 fatty acids

Phosphorus level: 0.84%

More than 50 years old, this company has set itself the goal from the beginning to provide the best possible diet for dogs. 

Moreover, Royal Canin is one of the few brands that also makes products for specific breeds. This is very impressive to me, as I myself experience that there can be many individual differences between dogs in terms of nutrition. 

The brand has a prescription line, and the Royal Canin Veterinary Diet Hydrolyzed Protein Moderate Calorie belongs to this line. 

The product has a moderated 21% protein content. The first ingredient is Brewers Rice. This grain has the same nutritional value as white rice but has better digestibility. 

The second ingredient is Hydrolyzed Soy Protein. Hydrolyzed protein sources are broken down proteins commonly recommended for dogs that have a problem digesting conventional proteins. 

And easy digestion of proteins contributes excellently to relieving the kidneys. Also, Soy Protein has less phosphorus content. The total phosphorus content of the product is 0.86% which is especially suitable for dogs with kidney disease. 

The fat sources in the recipe are Chicken Fat and Fish Oil. Both contain plenty of useful omega fatty acids. These are essential for the integrity of the skin and coat and the coat’s overall health. 

Other useful sources of nutrients can be found among the ingredients. Examples include various fiber sources and prebiotics. These are responsible for proper digestion. 

And the added vitamins and minerals ensure that your dog’s immune system works at maximum efficiency. 

The caloric content of the product is 307 kcal/cup. That is, it is suitable for dogs that need to maintain a healthy weight. 

Although the protein source is not the most appropriate in this recipe, I still consider it an acceptable option.

This food is also available in a canned wet form


Hill’s Prescription Diet k/d Kidney Care with Chicken

Key features:

  • The first 5 ingredients are Brown Rice, Brewers Rice, Pork Fat, Cracked Pearled Barley, Chicken

It is clear from all of Hill’s products that veterinarians and animal nutrition experts have been involved in the development. The Prescription Diet is a line of the brand with recipes for various health problems. The dog food currently reviewed is one of this line. 

The primary goal of Hill’s Prescription Diet Kidney Care is to support kidney function and joint health. Renal function is aided by low levels of phosphorus (0.32%) and sodium. And the content of omega fatty acids, chondroitin, and glucosamine has an excellent effect on the joints. 

The protein content of the product is shallow (12%). In other words, this is really worth using in justified cases. 

By the way, the source of protein is excellent quality chicken meat, which is a favorite of many experts due to its digestibility. And the egg product has an outstanding biological value. 

The primary ingredients are Brown Rice, Brewers Rice. These are nutritious grains. They provide plenty of energy, fiber, vitamins, and minerals for dogs. 

The main sources of fat are Pork Fat, Soybean Oil, and Fish Oil. As I have already written, they contain adequate amounts of omega fatty acids. 

The benefits are not over here. The product contains many added vitamins and minerals to ensure the normal functioning of your dog’s immune system. 

This product has a shallow protein content but with some degree of kidney damage. That is what is needed. In all other cases, you may want to choose an option with higher protein content.

Otherwise, the total protein content of the recipe is 20%, which is given by venison. It is outstanding quality, well digestible meat with a phosphorus content about the same as chicken.

You should know that, although I have selected all the products with great care, the first step should be to consult with your veterinarian. Thanks to the various tests, he will be able to determine the exact disease of your dog, its severity, and the treatment needed. Only then choose the right diet. And remember: the change of dog food should be gradual in all cases!


Why Do Dogs Need Phosphorus?

Phosphorus is an essential mineral that every dog ​​needs. It plays a key role in the growth of bones and teeth. It also helps with motor functions and the storage and transport of energy. 

So it is not worth missing this mineral from your diet unless it is causing problems. 

A developing puppy needs about 0.8-1.6% phosphorus. This figure is 0.6-1.2% for adults and 0.4-0.8% for seniors. So you can see that as your age progresses, your dog’s diet should contain less and less phosphorus. 

Otherwise, excessive intake of this mineral can cause kidney problems. General commercial dog foods, in many cases, contain more phosphorus than they need. 

Therefore, as your dog gets older, it is worth considering his or her individual needs and choosing a diet accordingly.

phosphorus content for foods

What’s wrong with a lot of phosphorus in a dog’s diet?

Excessive phosphorus intake can cause kidney problems or exacerbate pre-existing kidney disease. When this paired organ cannot perform its function properly, phosphorus and other minerals can accumulate and cause stones or other serious problems. 

As I mentioned, most commercial dog foods contain slightly more phosphorus than necessary, about 2%. 

This is not a problem as long as your dog’s kidneys are working properly. However, in kidney failure, other kidney problems, or old age, you inevitably look for a suitable diet. 

Grains and protein sources contain a lot of phosphorus. Getting rid of the former is easy, but not the latter. A healthy dog’s diet needs a sufficient amount of protein.

 A deficient protein diet can be just as harmful, so look for another solution. And the best solution is a low phosphorus diet.

What causes kidney disease in dogs?

Kidney disease, also known as renal disease, is widespread in aging dogs. In many cases, this condition can be inherited. 

There are two types of this condition. Acute kidney disease develops suddenly with symptoms and chronic over a longer period of time. 

Apart from aging and heredity, there are other causes of kidney disease. These are usually other diseases. Examples are:

  • Inflammation
  • Infections
  • Autoimmune disease
  • Parasites
  • Amyloidosis
  • Toxicity (e.g., from medicines)
  • Cancer

Symptoms of kidney disease in dogs

The symptoms of kidney disease can be very diverse. They also depend on the type of disease (acute or chronic) and the cause. 

It is usually not easy to recognize the symptoms of kidney disease because they can often resemble other diseases’ symptoms. However, I have collected the most common ones below:

  • Loss of appetite
  • Weight loss
  • Vomiting
  • Diarrhea
  • Bloody urine
  • Increased thirst
  • Increased urination
  • Decreased urination
  • Poor coat
  • Lack of energy
  • Incorrect and hunched posture
  • Towed motion

If you notice any of the above symptoms, take your dog to a veterinarian immediately. An accurate diagnosis can only be made after appropriate tests have been performed. The test can be a physical or blood or urine test or an X-ray. 

Treatment depends on the severity of the disease. In almost all cases, a change of diet is essential.

Types of low phosphorus dog foods

Of course, low-phosphorus dog foods have the same purpose. However, there may be differences in the ingredients. 

Depending on the severity of the kidney disease and individual needs, high or low protein foods may be needed. 

A diet high in protein and low in phosphorus is needed if your dog does not have severe kidney disease. This is because enough protein is important for muscle maintenance and cell regeneration. 

The situation is quite different when the kidneys are severely damaged. This is because these organs are responsible for filtering out various toxins and other substances. 

Damaged kidneys cannot filter out enough protein, so it accumulates in the blood and can lead to serious problems. 

A low protein and phosphorus diet helps relieve the renal system. This will help slow the progression and worsening of the condition. You may also want to reduce your dog’s sodium intake. 

Omega-3 fatty acids have a beneficial effect on the immune system and with it on kidney disease. 

Low phosphorus dog foods include both prescription and non-prescription. My list includes both types. It is important to consult your veterinarian about the options.

How these low phosphors diets can help?

These special diets are not so old in the pet food industry. Previously, lower phosphorus intake was achieved by limiting protein and other useful nutrients. This, of course, was not expedient. 

Today, more and more solutions are being developed to treat kidney disease. The goal of good low-phosphorus dog food is to provide the right amount and quality of protein and fatty acid in addition to the level of phosphorus in question. 

A solution may be to use certain ingredients that offset the phosphorus in the diet. But there are meats and other sources of protein that prove to be a low-phosphorus alternative. Thus, all dietary requirements are met for a dog with kidney disease.

Things to look in a good low-phosphorus dog food

Of course, you should definitely consult your veterinarian on this issue. This is even more true for prescription recipes. If your dog has kidney disease, you should choose the best possible product. Listed below are the ingredients you should look out for if your dog needs a low-phosphorus diet.

Protein

Whatever the diet, the most important ingredient in dog food is protein. After all, it builds up the whole body, regenerates cells, and plays a key role in thousands of more processes. 

Of course, in case of severe kidney failure, it is worth consuming less protein. However, this diet is also 18-20% of the minimum. For safety reasons, consult your veterinarian about the recommended dose of protein, as this number may be lower if warranted. 

In addition to the amount of protein, its quality is also critical. In sick dogs, meat with a high phosphorus content should be avoided. Stick to the identified animal meats so you can rule out the possibility of poor quality.

High phosphorus protein sources include sardines, liver, and beef. These occur in many dog ​​foods, but you should avoid them. 

Low-phosphorus meats include shrimp, duck, and other poultry such as chicken or turkey. Shrimp are very expensive, but duck and poultry are affordable options. 

As I mentioned, real meats are the best sources of protein. Nevertheless, some vegetable protein sources are of acceptable quality and low in phosphorus. Examples include quinoa, rice, and potatoes. 

It’s not good to have proteins from these plants as your dog’s primary protein sources, but they can be great supplements to a low-phosphorus diet.

Phosphorus

Thanks to the guaranteed analysis, the phosphorus content of a product can be easily determined. Most commercially available dog food has a phosphorus content of 2%. 

The recommended diet for a dog with kidney problems should contain about 0.6% phosphorus. Slightly larger quantities are still allowed, but rather look for one with less.

Other minerals

Some minerals can help your dog’s kidneys function. One of these is potassium. Potassium aids in the filtration process and the reconstruction of the kidneys. 

It doesn’t completely cure ailments, but it does help so much that you might want to consider the potassium content in your dog’s diet. Various supplements or high potassium ingredients (e.g., bananas) can also help. 

Another such mineral is calcium, which acts as a so-called phosphorus binder. Binders prevent phosphorus from entering the bloodstream. Instead, it enters the colon and leaves the body along with the feces. 

The amount of calcium required is about 500 mg per pound of dog food. Your veterinarian must determine the exact amount. The best sources of calcium are bones, eggshells, or other supplements.

Nitrogen traps

Nitrogen traps deliver by-products from protein metabolism to the colon instead of the kidney. This can significantly reduce kidney strain. 

This is because these nitrogen-containing by-products normally enter the kidneys and are excreted in the urine. Excellent natural nitrogen trap sources are probiotics and prebiotics.

Should I choose prescription or non-prescription low phosphorus dog food?

Both options have their advantages and disadvantages. Veterinarians often recommend prescription dog foods for kidney problems. 

These products have been specifically developed to treat these diseases. This can be reassuring for you as you don’t have to worry about the right phosphorus level. 

However, these recipes often have deficient protein and sodium levels. This can be a problem in the long run. Also, these products are more expensive. 

Please don’t misunderstand what I’m saying. I don’t want to talk you out of prescription dog food. Of course, if your veterinarian has recommended such a product, be sure to listen to it. 

However, if you have the opportunity to get the most out of your dog with over-the-counter food, it will be much more beneficial to both of you in the long run. 

The point is to consult your veterinarian about all the options available.

Frequently asked questions

What foods are the lowest in phosphorus?

Among the meats, poultry and lamb contain little phosphorus. Some fish (e.g., tuna) also have low phosphorus levels. Among the grains, quinoa, rice, and barley are the best choices. But potatoes are also a good alternative.

Is Chicken OK for dogs with kidney disease?

Various poultry (e.g., chicken) are excellent sources of protein for kidney disease because of their low phosphorus content.

Is Sweet Potato good for dogs with kidney disease?

Sweet potatoes are a great source of carbohydrates, with good digestibility and low phosphorus content. For this reason, it is also suitable for dogs with kidney disease.

What foods contain a lot of phosphorus for dogs?

Bones, certain fish (along with bones), dairy products, egg yolks, and organs contain a lot of phosphorus. You need to pay close attention to the amount of these foods in your dog’s diet if he or she has kidney disease.

My final verdict

A low phosphorus diet is crucial for dogs with aging or kidney disease. 

But as you can see, it’s not enough to provide the right phosphorus level. The quality of the ingredients in dog food is just as important. It is also an important issue whether we want to buy a prescription or non-prescription product. 

The Blue Buffalo Natural Veterinary Diet KS Kidney Support was clearly the best for me of the prescription products. This product is low in phosphorus and contains a sufficient amount of high-quality protein sources. 

Of non-prescription products, my favorite is Dr. Harvey’s Canine Health The Miracle Dog Food Pre-Mix

All you need to do with this recipe is add a low-phosphorus protein source, and you’re ready for the perfect kidney-sick diet for your dog. The other ingredients are simply perfect; all components of the product support overall health.
