Understanding Kidney Disease in Pets: What Every Pet Owner Should Know

As pet owners, we often think of our furry companions as family members. We cherish the love, joy, and loyalty they bring to our lives, which is why it's particularly distressing when we learn that our beloved pets have been diagnosed with a serious health condition. One such condition that affects many pets, especially as they age, is kidney disease. In this blog, we'll explore the ins and outs of kidney disease in pets, offering guidance and insights for pet owners who want to provide the best care and support for their furry friends.

What is Kidney Disease in Pets?

Kidneys are vital organs that play a crucial role in maintaining your pet's overall health. They filter waste products and excess substances from the blood, regulate blood pressure, and help maintain the right balance of electrolytes. When these vital organs become compromised, it can lead to kidney disease, also known as renal disease.

Kidney disease in pets can be acute or chronic. Acute kidney disease often occurs suddenly and can be caused by factors like toxins, infections, or blockages. Chronic kidney disease, on the other hand, develops gradually over time and is more common in senior pets.

Recognising the Signs

Early detection is key when it comes to managing kidney disease in pets. Some common signs to look out for include:

  • Increased Thirst and Urination: If your pet is drinking more water and urinating frequently, it could be a sign of kidney disease.

  • Loss of Appetite: A decrease in appetite or weight loss is a concerning symptom.

  • Vomiting and Diarrhoea: Gastrointestinal issues can be linked to kidney disease.

  • Lethargy: A lack of energy or enthusiasm might indicate a problem.

  • Poor Coat Condition: If your pet's fur becomes dry and unkempt, it could be a sign of kidney disease.

If you notice any of these symptoms, it's essential to consult your veterinarian. They can perform blood and urine tests to diagnose kidney disease.

The Role of Diet

Diet plays a significant role in managing kidney disease in pets. Studies have found that cats fed a prescription renal diet versus regular cat food after diagnosis, have a doubled survival time. Your veterinarian may recommend a special prescription diet designed to support kidney function. These diets are lower in protein, phosphorus, and sodium and can help ease the workload on the kidneys.

There are many different brands, and varieties of prescription diet, so if your pet doesn't seem to like the first one, try some more! When possible, introduce a new food gradually, this way most pets will accept a new diet more readily.

There are also some supplements that can be added to 'regular' food to improve its compatibility with kidney disease, but always ask your vet before trying these.

If you really are struggling with a new diet, then you may ask your vet if they can recommend a nutritionist to help you tailor a diet to your pet's needs. Similarly, if your pet is refusing to eat, speak to your vet about alternative feeding methods and appetite stimulants.

Medication and Fluid Therapy

Depending on the stage of kidney disease, your veterinarian may prescribe medications to help manage symptoms and slow the progression of the disease. Additionally, fluid therapy can help maintain hydration and support kidney function.

Regular Veterinary Check-ups

Regular veterinary check-ups are crucial for pets with kidney disease. These check-ups allow your vet to monitor your pet's condition, adjust treatment plans as necessary, and catch any potential complications early.

Similarly, pets with kidney disease must have regular blood pressure checks as kidney disease and high blood pressure can often go hand in hand.

Supporting Quality of Life

While kidney disease can't be cured, you can still support your pet's quality of life. Here are some tips to help your furry friend:

  • Maintain a calm environment: Reducing stress can help your pet feel more comfortable.

  • Provide easy access to water: Make sure your pet has access to clean water at all times.

  • Administer medications as prescribed: Follow your vet's instructions to manage symptoms effectively.

  • Maintain a regular routine: Consistency can help reduce anxiety and stress for your pet.

  • Lots of love: Shower your pet with affection and attention to keep their spirits high.


Kidney disease is a challenging diagnosis for pet owners to face, but with proper care and support, your furry friend can continue to enjoy a good quality of life. Remember to consult your veterinarian for a diagnosis and a treatment plan, maintain a balanced diet, administer medications as directed, and provide a loving and stress-free environment. By following these guidelines, you can help your pet manage kidney disease and continue to enjoy a happy and fulfilling life by your side.
