Yes, Stage 4 renal failure in dogs causes significant discomfort and can be painful due to toxin buildup, leading to symptoms like nausea, vomiting, lethargy, mouth ulcers, and overall malaise, often described as feeling "icky" or like a bad hangover, requiring veterinary management for comfort.
Yes, kidney failure in dogs can be painful. Kidney failure in dogs can be painful because the kidneys are responsible for filtering body waste and toxins. When they fail, these toxins build up in the bloodstream and can cause discomfort and pain.
The life expectancy for individuals with stage 4 kidney disease can vary widely and is influenced by age, overall health, treatment choices, and access to medical care. With appropriate management and treatment, many people can live with stage 4 CKD for several years.
Prognosis is associated with severity of disease. Studies have shown shorter median survival times in dogs with higher IRIS stages. Median survival time for IRIS Stage 1 dogs was over 400 days, Stage 2 ranged from 200 to 400 days, Stage 3 ranged from 110 to 200 days, and Stage 4 ranged from 14 to 80 days.
Symptoms of stage 4 kidney disease
Urination changes (foamy; dark orange, brown, tea-colored or red if it contains blood; and urinating more or less than normal) Kidney pain felt in their back. Sleep problems due to muscle cramps or restless legs. Nausea and/or vomiting.
Patients may experience a wide variety of symptoms as kidney failure progresses. These include fatigue, drowsiness, decrease in urination or inability to urinate, dry skin, itchy skin, headache, weight loss, nausea, bone pain, skin and nail changes and easy bruising.
We found that participants with progressive CKD spent a median of 7.9 years in stage 3a, 5 years in stage 3b, 4.2 years in stage 4, and <1 year in stage 5.
It depends on the stage of the disease, the dog's age and overall health, and how they respond to treatment. Early to mid-stage CKD: Dogs may live 1–3 years with proper care. Advanced-stage kidney failure: Life expectancy can range from a few weeks to several months.
Although most dogs do not recover completely from chronic kidney failure, the condition can often be successfully managed, allowing pets to live a normal life for months or years. Acute Renal Failure - Acute kidney failure is characterized by a suddenly decrease in kidney function over a period of hours or days.
Loss of Appetite and Weight Loss
Dogs experiencing kidney failure may refuse food or eat significantly less than usual. Over time, this can lead to noticeable weight loss, muscle wasting, and a lack of energy.
The ideal diet for a dog in the advanced stages of kidney failure is lower in protein, low in phosphorus, and is not acidified. This type of diet helps reduce the amount of protein wastes or metabolic toxins that may make your pet feel sick and lethargic.
Unfortunately, CKD is usually a progressive disease. However, progression is relatively slow, and pets with CKD often survive for many months to years with a good quality of life. It is important to recognize that in pets with advanced CKD, treatment will not reverse or stop the disease but will slow it down.
Chronic kidney failure can lead to tremors. So can neurological problems that may include inflammatory brain diseases. An Addisonian crisis, a condition related to an underactive adrenal gland, and demyelinating disorders may also lead to shaking in dogs. Dogs may shake when their anal sacs are full.
Increased thirst and urination, vomiting, and low energy can indicate kidney problems but also appear with diabetes, liver disease, or urinary tract infections. Only proper veterinary evaluation can determine if your dog's kidneys are failing.
A dog's kidney failure diet should contain plenty of water. Fresh food diets can be quite beneficial in adding moisture to your dog's diet. Always be sure your dog has access to fresh, filtered water at all times. Even if they have plenty of access to water, keep an eye on your dog to watch for signs of dehydration.
As kidney disease progresses in your dog, they can become very lethargic and prefer to sleep much of the day. When they are awake, their back legs may appear weak and cause them to shake while they walk or even stumble and fall.
Sores in the mouth: When kidney disease becomes very advanced, dogs can develop extremely painful sores in the mouth. These indicate the disease is end-stage and are incredibly painful, so if your dog is developing mouth sores I recommend euthanasia.
It's most often related to infections or toxinss. Acute kidney failure in dogs may happen due to dehydration or a bacterial infection called leptospirosis, which a dog can contract by ingesting contaminated water. Other causes of acute kidney failure in dogs include ingestion of: Human heart medications.
The Link Between Bad Breath and Kidney Failure
One of the waste products that can build up is urea. Excessive urea (called uremia) can cause the dog's breath to smell like ammonia, urine or even “fishy” when they exhale.
Stage 4: Kidney failure is end-stage, and symptoms intensify, including extreme lethargy, dehydration, and loss of appetite. At this stage, the dog's kidneys are no longer able to function effectively, and euthanasia may be considered if quality of life deteriorates significantly.

Foods to Avoid for Dogs with Kidney Disease
Certain foods put extra stress on the kidneys and should be avoided: High-protein foods (especially red meat) Jerky treats, bones, pig's ears, rawhide.
In the last weeks and days of kidney failure, signs that death is near include: Little or no urine output. Decreased blood pressure. Decreased body temperature.
