Buying Guide To Buying Best Low Phosphorus Dog Food

What Is Kidney Disease? 

Kidney disease is most often caused by chronic dehydration or worse. Dogs feel thirsty but drink very little water. Drinking more water would not provide relief because the kidney filtration system simply cannot function properly when it does not have enough blood flowing to it.

Dogs don’t always show symptoms as humans do, and that is why they need frequent visits with their veterinarian for screening tests to detect any early signs of deterioration of their kidney function before damage starts taking its toll on the dog’s quality of life. 

These tests include routine urinalysis, urine culture and sensitivity testing (to identify possible infection), blood pressure checks, blood chemistries (e.g., BUN and creatinine), as well as additional diagnostic.

What Is Phosphorus?

Phosphorus is a dietary mineral that plays a vital role in forming bones and teeth. It also helps regulate energy levels.

Phosphorus is an essential nutrient. It’s needed in larger doses than you’re able to produce on your own (most animal cells only make small amounts).

All animals need phosphorus for healthy growth and development. Still, dogs have special needs for this vitamin because many commercial dog foods are high in phosphorus relative to calcium. There are two forms of phosphorus-metaphosphates – organic and crystalline. 

Animals can meet their phosphorus needs through typical meat, eggs, dairy products, fish oils, and vegetables. Plant foods contain some phosphorus compounds as well as

Why Is Calcium Important For Dogs With Kidney Disease?

Unfortunately, calcium is more than just an essential mineral for humans. It’s also necessary for dogs with kidney disease. Calcium is used to control the acid-base balance in a dog’s blood by entering cells that store bicarbonate and helping neutralize these acids. 

This assistance allows hydrogen ions to exit the cell. They would otherwise accumulate and produce too much acidity inside the cell (more acidic environments cause most cellular functions to be impaired). 

In short, low calcium levels put tremendous stress on your dog’s kidneys since they have to work harder without it, which can lead to their health being negatively impacted. 

With this in mind, it becomes imperative that you ensure adequate intake of dietary calcium from food or supplements—now more than

Which Dogs Need a Low Phosphorus Diet?

Phosphorus restriction tends to be recommended for those with compromised kidney function (even in the absence of known kidney disease). 

It may also be indicated if a dog has had repeated or uncontrolled vomiting and diarrhea, certain endocrine gland diseases, or underweight. Researchers have theorized that phosphorus restriction may help with suspected, but not yet diagnosed, chronic kidney disease.

How Much Phosphorus Should Dog Food Have?

Dog foods should have between 0.5% and 1.5% phosphorus content.

Dogs consume more phosphorus than calcium per gram of food, so it is crucial to control phosphorus in their diets. 

Too much phosphorus leads to a condition called hyperparathyroidism, which causes the dog’s kidneys to conserve too much phosphorus from their diet for fear that they will not be able to get enough off our bones or intestinal tract when needed. 

Hyperparathyroidism can lead to kidney disease and heart disease as well.” Too much” is harder to quantify. Still, amounts typically attributed by vets range from 0.5%-1.5%. Higher concentrations may seem like more meatloaves at first, but

Which Is Better: A Diet High In Protein Or Low In Protein?

The protein content of each diet should be based on the needs of the individual animal.

For dogs, an excellent general rule is to provide about one-third of total calories from protein. However, high-protein diets are not desirable for foods that are nutrient-dense and calorie-deficient. 

Cats do better with a high-fat diet but low in protein, while canine athletes often need higher levels of both nutrients. It’s always best to discuss specific nutrition requirements with your vet before you start planning any kind of feeding plan for your dog or cat!

What Is The Difference Between Prescription And Non-prescription Low-phosphorus Canine Diets?

Formulations for prescription diets must be approved by AAFCO and are manufactured by high-quality companies that contract veterinary nutritionists. 

Non-prescription diets have no such guidelines, so each company is responsible for developing its own formulation, resulting in cheaper ingredients.

Prescription low phosphorus foods have a shorter list of healthy ingredients to reduce the phosphorus content and increase the digestibility of these nutrients in your pet’s diet while maintaining its nutritional value. 

This leaves more room for seemingly healthier food sources that can provide readily available protein or increased fiber. 

If you do not know what foods are best for your individual pet, talk to your veterinarian about dosage needs and how to come up with a cost-effective solution.

How To Change Your Dog’s Diet Effectively?

Things to consider before changing your dog’s diet:

Switching Foods without Prescription Drugs

It’s okay to switch foods as long as you’re not switching out to something your dog cannot eat, like a raw food diet, for example. Still, it takes a while for dogs’ digestive systems and brains to change gears in how they process things.

So be prepared for the potty problems and mood changes until their system adjusts again–which could take up to three weeks on average (this does not include any extreme cases where the digestive system is so used to what it eats that there will be constipation issues).

What Are The Symptoms Of Kidney Disease?

Kidney disease in dogs may eventually lead to severe dehydration and lethargy. This is because they may drink excessive water, start lifting their leg to urinate more often, strain or whine during the act, and then not produce anything. 

There could also be dark yellow or reddish urine with a pungent smell.

How Do I Get My Dog To Adjust To Their New Low Phosphorus Dog Food?

The easiest way to transition a dog off of a higher phosphorus food is by slowing the process down. Change their diet at just one meal per day, and go from there. 

Some people may start off feeding raw foods with lower phosphorus content than what they’re used to in commercial dog food. In other words, you can’t just change their entire diet overnight – that would likely promote digestive distress or toxification symptoms in your pet.

Another perspective you should keep in mind is if you are transitioning to a lower phosphorus diet, then your pet will find it easier digesting due to the slower breakdown times for protein synthesis and absorption when cell turnover slows down going into old age (e.g., because

Should I Change The Treats I Give A Dog With Kidney Disease?


Dogs with kidney disease are often fat and have high cholesterol, but your dog can still enjoy a few treats every now and then. 

Just keep the amount at a minimum, and make sure to observe which treat you’re considering feeding for signs of any issues like inflammation or vomiting. If there’s no concern, there should be nothing wrong with treating them from time to time!

Are There Specific Foods A Dog With Kidney Disease Shouldn’t Eat?


A dog with kidney disease should be fed a specific diet, but the diet is not as restrictive or strict as it used to be. For example, older protocols suggested inducing protein breakdown or inhibiting amino acid metabolism. 

Recent evidence has shown that these types of diets might make kidney disease worse. A recent study published in the Journal of Veterinary Internal Medicine found that renal function stabilization and life expectancy improved among dogs eating pelleted food for 12 weeks without changes in clinical lab values, urine concentrations, or daily water intake. 

This proves that you don’t always have to put your dog on a special diet if they have kidney disease.

How Can I Keep My Dog With Kidney Disease From Getting Dehydrated?

You can provide frequent small amounts of cool water and snacks. For example, offer your dog five to 10 teaspoons of water every hour with a snack like a few bites of dry low-fat canned dog food. 

A pet’s appetite varies with activity level as well as the time of day, so it’s best to experiment to find out about the amount that your animal will want to eat during and after exercise. 

Make sure that you have healthy low-salt foods available in addition to high salt ones because if your pets don’t want those, he/she may prefer unsalted raw meats and vegetables such as carrots, celery sticks or whole green beans. 


The best low-phosphorus dog food will be able to provide your pet with all the vitamins and nutrients they need without causing any harm.
