In the simplest of terms, a low-phosphorus dog food is just that – a food that is low in phosphorus. Phosphorus is an essential nutrient that works with calcium to keep your dog’s bones healthy and strong. Your dog needs slightly less phosphorus than calcium, but he still needs a significant amount of phosphorus in his diet unless, of course, it starts to cause problems. As your dog gets older, his needs for both calcium and phosphorus start to decrease.

At the height of his growth and development, a dog needs about 1.0% to 1.8% calcium in his diet and somewhere between 0.8% and 1.6% phosphorus. Once your dog reaches half his adult size, his needs drop to 0.8% to 1.5% calcium and 0.6% to 1.2% phosphorus. As an adult, they drop even more to 0.5% to 0.9% calcium and 0.4% to 0.8% phosphorus. In older dogs, if the phosphorus content of the diet is too high, it can cause kidney problems in which case a low-phosphorus diet may be helpful.

What Should You Know About Kidney Disease in Dogs?

Also known as renal disease, kidney disease is a fairly common condition in dogs, especially as they start to get older. There are two types of kidney disease – acute and chronic. Acute kidney disease develops quickly and symptoms may appear suddenly while chronic kidney disease sets in slowly and often with nonspecific symptoms. There are a number of different causes for kidney disease aside from factors like age or genetics. Here are some of the other potential causes for this condition:

  • Infections (viral, fungal, or bacterial)
  • Parasite infestation
  • Cancer
  • Protein deposits in the kidney (amyloidosis)
  • Inflammation
  • Autoimmune disease
  • Toxicity from poison or medications
  • Inherited disease

The symptoms of kidney disease may vary not only according to the type (acute vs. chronic) but also according to the cause. It is also important to know that some of the symptoms for this disease overlap with symptoms of other conditions like pancreatic disease or liver disease – this can sometimes make it tricky to find an accurate diagnosis. Some of the most common symptoms of kidney disease are these:

  • Increased thirst and urination
  • Decreased frequency or lack of urination
  • Blood in the urine
  • Loss of appetite
  • Vomiting
  • Diarrhea
  • Weight loss
  • Lack of energy
  • Hunched posture
  • Reluctance to move
  • Poor coat quality

Upon completing a physical exam, your veterinarian may notice additional symptoms such as pale gums, enlarged kidney, ulcers in the mouth, bad breath, swelling of the limbs, swollen abdomen, and high blood pressure. To confirm the diagnosis, your vet will probably take a chemistry panel using your dog’s blood to test for blood urea nitrogen, creatinine, and phosphorus levels. A urinalysis may also be helpful in confirming a diagnosis and, in some cases, an x-ray may help as well. Treatment options for kidney disease often include fluid therapy, kidney dialysis, and dietary changes.

The Top 3 Low-Phosphorus Brands

If your dog needs a low-phosphorus diet, you might be able to get one directly from your veterinarian. Be careful, however, because not all low-phosphorus dog foods are made with high-quality ingredients. In fact, some of the pet food brands that are best known for veterinary and prescription diets use low-quality ingredients including by-products and fillers. To find a low-phosphorus product that also offers decent quality, we recommend the following three brands:
