What Causes Kidney Disease in Dogs?

Just like in humans, your dogs kidneys are responsible for filtering out waste, balancing nutrients, and increasing red blood cell production. They also play a vital role in helping regulate blood pressure and metabolize calcium.

Kidney failure can result in a rapid decline of multiple functions of a dogs body and cause high blood pressure, potassium deficiency, and other conditions.

Kidney disease can be congenital, which means the dog was born with it. It can also be acquired through inflammation, stones, infections, toxins, or cancers of the kidney that leads to permanent damage. Urinary obstruction can also lead to kidney problems, due to the kidneys not getting enough oxygen.

Acute Kidney Failure

Acute or short-term kidney disease happens fairly quickly and lasts several days. In dogs, it is typically caused by the ingestion of toxins such as household chemicals, spoiled or contaminated food.

A bacterial infection such as leptospirosis can also cause dogs to develop kidney disease. Other causes include dehydration, snake bites, and heat strokes.

Because of the sudden malfunctioning of their kidneys, dogs suffering from acute kidney disease require immediate medical attention. They will need to undergo a range of diagnostics that will help assess the underlying cause of kidney disease and the level of dysfunction.

The vet may require blood tests, urine tests, X-rays, ultrasound, and blood pressure measurements.

Intensive treatments are usually in the order in cases of this type of kidney disease.

Treatments for Acute Kidney Disease

• Intravenous fluid therapy
• Antibiotic medication
• Nutritional support
• Medication for nausea and gastric irritation
• Monitoring of urine and blood
• Monitoring and treatment of any secondary health problems

Chronic Kidney Failure

Chronic kidney disease is the slow or gradual decline of the kidneys health. It is more common in senior adult dogs. More than 10% of dogs aged over 15 have chronic kidney disease. While not common, kidney disease occurs in younger pups as well

Dogs with chronic kidney failure may experience mild symptoms that may go unnoticed at first. The sooner it is discovered, the better it can be managed by pet owners and help their pups live comfortably.

Symptoms of Kidney Disease

• Increased water intake
• Increased urine output
• Weight loss
• Sometimes decreased appetite
• Occasional vomiting, increasing with frequency over time
• Blood in urine
• Signs of dental disease like pale gums, bad breath, mouth ulcers

Diagnostics

Vets monitor and diagnose kidney disease through blood tests that would indicate the following:

• Urea and creatinine rise with canine kidney disease
• Phosphate rises with long term kidney disease
• Regular full blood profiles can also monitor all the body systems. Changes in any other system will also affect a dogs kidneys.

Urine tests are also important. Dogs with poor kidney function are unable to concentrate or dilute urine.

• A Sedivue test can be used to detect infection in the renal system. Controlling any infection is important for maintaining kidney function.
• The presence of protein may indicate a need for medication.

How Can Kidney Diseases in Dogs be Prevented?

Acute kidney failure can be prevented by taking a few steps in making sure your dog is protected from accidental ingestion of toxic substances. Make sure all medications, household cleaning chemicals, insecticides, antifreeze, and other chemicals are all properly resealed and stored in an area that they cannot reach.

Ensure that containers or such substances are also disposed of properly and away from your pups. The garbage can is another thing that bored dogs can easily get into. Here is where they can find a treasure trove of bottles of cleaning materials, discarded chemical-soaked rags, and contaminated food.

The smell of leftover food can definitely attract pups who always have food in their minds. Rotten food thrown in the trash is contaminated with harmful bacteria and possibly other chemicals present in the trash. Make sure that it is covered and not easily accessed by your dogs.

Avoid feeding your pets foods that can be harmful to them. Human foods such as chocolates, raisins, alcohol, coffee, artificial sweeteners, etc.

What to Feed Dogs With Kidney Disease

The dietary changes that need to be made will depend on the severity of the dogs kidney disease. In general, most vets would prescribe a diet that is lower in phosphorus, sodium, and protein.

Working with your vet is the best way to determine the specific diet and nutrient levels that are appropriate for your dog.

Water

Because malfunctioning kidneys are no longer able to are no longer as effective at excreting waste products as they used to, it is also unable to concentrate urine as needed.

In order to continue to rid the body of its toxins despite more dilute urine, the body compensates by increasing thirst.

Your pup must have access to fresh, clean water at all times. You can also increase her moisture intake by feeding canned dog foods approved by your vet. Low sodium broth made from boiled chicken breast, tuna juice, or low sodium vegetable broths can also be poured over their meals for added hydration.

Protein

Foods with lower protein levels are typically prescribed by vets for dogs with kidney disease. This greatly reduces the strain on the kidneys and decreases the need for the excretion of protein itself through the kidney.

This is why prescription dog food formulated for kidney or renal care all have low protein percentages compared to regular dog foods. As a general rule, the recommended range of protein on a dry matter basis for dogs with chronic kidney disease is around 14-20%.

However, the range of protein levels that will be prescribed by your vet will still depend on the severity of the kidney disease among other things.

Please note that the dry matter basis is not the numbers you see in the guaranteed analysis printed on the packaging of dog foods. To compute for the dry matter basis (DMB) percentage of a particular nutrient in a brand of dog food, we can use this equation:

DMB% = As fed basis% * 100% / (100% Moisture%)

Phosphorus

Restricting the dietary phosphorus in dogs can help slow down the progression of kidney disease. Because phosphorus content is related to protein content, it is impossible to achieve very low levels of phosphorus without also lowering the protein content.

Meats with bones are commonly higher in phosphorus compared to protein sources like boneless chicken breast. Organ meats can also have higher phosphorus content.

Sodium

The sodium intake of dogs with kidney disease or kidney failure must also be reduced. This eases the workload on the kidneys and helps prevent high blood pressure.

Aside from the dogs meals, the treats should also be lower in sodium. Avoid salty treats like cheese, deli meats, and treats that are high in artificial flavors.

Omega 3 Fatty Acids

The anti-inflammatory properties of omega 3 fatty acids are beneficial to dogs with kidney disease. The production of inflammatory compounds creates oxidative stress in the tissue of the diseased kidneys.

Omega 3 fatty acids contribute to slowing down the progression of the disease by helping reduce the protein leaking' through the kidneys.

Conclusion

Pets with renal failure no matter what stage can be quite challenging to treat, especially for chronic kidney disease which is irreversible.

Because of the delicate nature of the disease, you will need to work closely with your vet to determine which aspects of kidney health you need to work on to prevent renal failure from progressing further.

For most dogs, a combination of food with the appropriate nutrient levels, medication, fluids, and supplements is what works best to slow down the progression of the disease. The appropriate diet and treatment will greatly depend on the severity of the renal damage.

We hope that our list has made it easier for you to find the right dog food that will help your pooch live comfortably and happily for the rest of her years.
