- Your vet will probably suggest a low phosphorous diet for your senior dog if it is showing signs of developing kidney disease, which results in renal failure in its advanced stages.
- Dogs with weak kidneys can’t remove excess phosphorous and other toxins from their bodies, and phosphorus can build up to dangerous levels over time. Excess phosphorus damages tissues, bones, and important internal organs.
- You can help your dog lower its phosphorous levels by cutting these items down in its diet: dairy products, whole grains, organ meats, salmon, shellfish, soy-based foods, and pork.
If your dog has kidney disease or renal failure, your vet may have recommended a low phosphorus dog food. Unfortunately, these foods are expensive, and you can only get them with a prescription. Is it possible to get non-prescription dog food that is high quality and fits your budget? We put it to the test, and we found these brands that fit the bill.
How To Use Low Phosphorus Dog Food
Phosphorus is an important mineral that helps a dog’s bones and tissues grow strong. Along with calcium, it’s important for building bone density in humans and animals. Getting too much, however, can be harmful.
Normally, a dog’s kidneys remove excess phosphorus and other toxins from her body. Dogs with weak kidneys can’t remove these toxins, and the phosphorus builds up to dangerous levels. Excess phosphorus damages tissues, bones, and important internal organs.
This can have severely negative effects, including:
- Weak bones.
- Loss of vision.
- Urinary problems.
- Blocked blood vessels.
Since most phosphorus comes from food, the best way to control it is with a low phosphorus diet.
What is Low Phosphorus Dog Food?
It can be tricky to give dogs the right food when they need to control their phosphorus levels. Dogs need protein, but many high-protein foods are also high in phosphorus. A low phosphorus dog food is low in protein, but it supplies the nutrients your dog needs.
When do You Need Low Phosphorus Dog Food?
Many senior dogs develop kidney disease, which becomes renal failure in its advanced stages. If your dog has shown signs of kidney disease, your vet has probably suggested this type of diet. With the right diet, dogs can reverse kidney disease. Even those with chronic renal failure can manage the disease and live a longer, happier life.
You can buy vet-recommended dog food, or you can use over-the-counter dog foods that are equally good. The foods on our list are available without a prescription.
Are There Other Ways to Keep Phosphorus Levels Low in Dogs?
Besides using the right dog food, you can also control your dog’s intake of phosphorus.
Avoid feeding your dog the following as meals or snacks:
- Dairy products
- Whole grains
- Organ meats
- Soy-based foods
How do You Get Your Dog to Eat New Food?
When you start your dog on a new food, don’t make a sudden switch. Start by adding a small amount of the new food to your dog’s regular food. Over the next few feedings, gradually increase the amount of the new food and decrease the amount of the old food. Finally, start feeding only the new food.
Support Your Dog’s Kidney Health
The right food can help you keep your dog happy and healthy, even if your dog has kidney disease. These foods and treats are all good choices when it comes to healthy eating.
Our Criteria and Experience: How We Chose the Best
When reviewing these products, we researched recommendations from pet owners who have dogs with kidney conditions. They explained how frustrating it was to find foods that were vet-recommended, fit their budget, and were low in phosphorus. These were factors we took into account when looking for products to review.
Most of these products cost more than regular, non-prescription dog food, but the cost is low compared to the extremely high costs of kidney treatments. Although it might seem like a hit to your budget, high-quality dog food is the lowest-cost way to preserve your dog’s health.
Another important factor was taste. Many of us know that our pets dislike the flavors of most vet-recommended and prescription foods. Our reviewers agreed that Blue Buffalo scored the highest in this regard. It was the easiest one to get most dogs to eat. It is also affordable compared to prescription brands. For these reasons, it was the best overall. The Forza10 was another winner in the taste department, but some users said the kibbles were too large for small dogs. We wrapped up our review with some low phosphorus dog treats that will let you healthily reward your dog.
