Knowing the stage of your dog's kidney disease requires a veterinarian to perform blood tests (specifically for creatinine and SDMA) and a urinalysis to check for dilute urine and protein loss, typically using IRIS guidelines. The disease is classified into four stages, with Stages 1-2 often showing few symptoms and Stages 3-4 presenting as increased thirst, weight loss, and vomiting.

How do I know what stage of kidney disease my dog has?

Following diagnosis of CKD, the IRIS Board recommends using serum creatinine or SDMA (ideally both) to stage CKD with substaging based on assessment of arterial blood pressure and proteinuria. Results of both tests should be interpreted in light of patient's hydration status.

How do I know if my dog's kidney disease is getting worse?

The clinical signs of more advanced kidney failure include loss of appetite, lethargy, vomiting, diarrhea, and very bad breath. Occasionally, ulcers will be found in the mouth.

How fast does kidney disease progress in dogs?

Kidney disease progression in dogs varies widely, from slow, years-long declines in chronic cases (CKD) to rapid, days-long failure in acute cases, often taking years to show signs because kidneys have reserve function, with factors like age, breed, hydration, and other illnesses influencing speed, though treatment aims to slow progression, not cure it.

What does stage 3 kidney disease look like in dogs?

Some dogs with early Stage 3 chronic kidney disease have mild symptoms like intermittent loss of appetite, change in haircoat, or weight loss. Other dogs, especially those with creatinine values closer to 5, may feel quite unwell. Some dogs may vomit, have diarrhea, or be a lethargic dog.

How long can a dog with stage 3 kidney disease live?

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.

What are the symptoms of stage 2 kidney disease in dogs?

Symptoms that your pet is showing include: drinking excessively, weight loss, frequent urination, vomiting, significant decrease in appetite, significant increase in lethargy. At this stage medications and treatments are necessary to maintain the quality of their life.

How long does it take to go from stage 3 to stage 4 kidney disease?

There's no fixed timeline to go from Stage 3 to Stage 4 kidney disease (CKD); it varies widely, with some people staying in Stage 3 for years or even decades, while others progress faster, depending on risk factors like diabetes, high blood pressure, heart disease, age, and proteinuria. Some studies show about half of Stage 3 patients progress to Stage 4 within 10 years, while others note median times in Stage 3 can be over 12 years, highlighting that management with lifestyle changes and medication can significantly slow progression.

What color is a dog's poop when the kidneys fail?

In severe kidney failure, the amount of urine may actually decrease, or the pet may stop making urine altogether. Other signs as things get worse include digested blood in the stool making the stool look black and tarry, or vomiting digested blood, which looks like coffee grounds.

Kidney damage isn't usually reversible, but there's a lot you can do to slow further kidney damage.

How to slow progression of kidney disease in dogs?

How long can a senior dog live with kidney disease?

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.

Can stage 2 kidney disease be reversed in dogs?

It is important to recognize that in pets with advanced CKD, treatment will not reverse or stop the disease but will slow it down. Your veterinarian will need to monitor your pet regularly to assess whether the disease has progressed and, if so, determine a new course of therapy.

How to determine the stage of kidney disease in dogs?

Sub-staging of kidney disease involves screening for urine protein loss and measuring blood pressure. A urine protein: creatinine ratio is performed on a urine sample and the protein amount is classified as either non-proteinuric, borderline proteinuric, or proteinuric.
