Is your dog drinking more water than usual? Have they seemed a little off lately, perhaps with a reduced appetite or a general lack of energy? These can be subtle but important signs that something is wrong. In dogs, as in humans, the kidneys are vital organs that perform crucial functions to keep the body healthy. When they stop working effectively, it can lead to a life threatening condition known as kidney disease, kidney failure or renal disease.
This post is designed to help you understand canine kidney disease, how to spot early symptoms and how it is diagnosed and treated.
Understanding the Kidneys’ Role
Your dog’s kidneys act as the body’s primary filtration system. They are responsible for:
- Filtering waste products from the blood, such as urea and creatinine, and excreting them in urine.
- Balancing important substances like electrolytes and water.
- Regulating blood pressure.
- Producing hormones that help with red blood cell production.
When a dog’s kidneys begin to fail, they lose their ability to filter the blood. As a result, waste products start to build up, leading to a toxic state called azotaemia. This build-up of toxins is what causes many of the noticeable symptoms of the disease.
Recognising the Signs and Symptoms
Kidney disease is often a gradual process, and the early signs can be easy to miss. However, recognising these symptoms early is critical for a better prognosis.
Key Symptoms to Look For:
- Increased thirst and increased urination (polydipsia and polyuria): This is one of the most common early signs. As the kidneys lose their ability to concentrate urine, the dog needs to drink more to stay hydrated and flushes out more dilute urine.
- Vomiting, loss of appetite, and weight loss: The accumulation of toxins in the bloodstream can cause nausea and a general feeling of being unwell, leading to a reluctance to eat.
- Lethargy and weakness: Your dog may seem tired, less interested in playing, and generally lacking in energy. This is a direct result of the toxins affecting their nervous system and overall body function.
- Pale gums: Anaemia, a common side effect of advanced kidney disease, can cause your dog’s gums to look white or paler than usual.
- Bad breath (uremic breath): The build-up of toxins can give your dog’s breath a distinct, unpleasant smell similar to urine or ammonia.
If you observe any of these symptoms, it’s a strong indicator that something is wrong and your dog requires urgent veterinary care.
Causes and Risk Factors
Kidney disease has many potential causes, but is most commonly associated with a dog’s age. It is often a chronic condition that progresses slowly over time.
- Age: The most significant risk factor is age. Kidney function naturally declines over a dog’s lifetime.
- Genetic Predisposition: Certain breeds, such as Yorkshire Terriers, Cavalier King Charles Spaniels, German Shepherds, Boxers and Samoyeds, may be genetically predisposed to kidney problems.
- Diet: A dog’s diet can play a significant role. High-protein diets or those with improper mineral balances can place additional strain on the kidneys.
- Other Medical Conditions: Kidney disease can be a secondary condition caused by bacterial infections, high blood pressure, or dental disease.
- Toxic Substances: Ingesting toxins such as antifreeze, certain human medications like ibuprofen and aspirin, or foods like grapes and raisins can cause sudden and severe kidney failure.
If you suspect your dog has ingested a toxic substance, this is an immediate emergency. Please contact The Lighthouse immediately on 01243 765247.
Diagnosis and Treatment
A diagnosis of kidney disease can only be made by a vet through a combination of tests. The sooner a diagnosis is made, the sooner treatment can begin.
- Blood tests: These are used to check for elevated levels of blood urea nitrogen (BUN) and creatinine, which are key indicators of kidney function.
- Urine analysis: This test assesses the concentration of the urine and looks for the presence of protein and other abnormalities.
- Ultrasound: An ultrasound can provide a detailed view of the kidneys to check for cysts, kidney stones, blood flow, signs of infection and changes in size and shape.
There is no cure for chronic kidney disease, but it can be effectively managed to slow its progression and improve your dog’s quality of life. The main treatment options include:
- Specialised Renal Diet: A vet-prescribed diet low in phosphorus and protein can significantly reduce the workload on the kidneys.
- Fluid Therapy: Subcutaneous or intravenous fluids can help flush toxins from the body and keep your dog hydrated.
- Medications: Various drugs can be prescribed to manage symptoms, such as medications to control blood pressure, reduce nausea, or bind phosphorus in the diet.
- Supplements: Certain supplements may be recommended to help manage specific symptoms.
Living with a Dog with Kidney Disease
Managing a dog with kidney disease is a partnership between you and your vet. With supportive care, many dogs can live a happy life for months or even years. Be prepared to provide consistent care, including:
- At-home monitoring: Keep a close eye on your dog’s appetite, thirst, and energy levels. Report any changes to your vet.
- Dietary changes: Be patient and persistent when transitioning your dog to a new food.
- Follow-up visits: Regular vet check-ups are essential to monitor the disease’s progression and adjust treatment as needed.
