Determining 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 urine concentration (USG) and protein levels. Veterinarians typically use the IRIS (International Renal Interest Society) system, which ranges from Stage 1 (early/mild) to Stage 4 (severe/end-stage).

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 long do dogs live with stage 3 kidney disease?

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.

How fast does kidney disease in dogs progress?

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.

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.

Can stage 3 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.

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

Dogs with acute kidney failure often show dramatic symptoms like persistent vomiting, complete refusal to eat or drink, and severe low energy. Without quick medical help, this condition can be fatal.

How to slow progression of kidney disease in dogs?

Limiting dietary phosphorus in dogs with CKD appears to help delay disease progression. Phosphorus content in the diet is linked to protein content, so to achieve lower phosphorus levels, there must be some reduction in dietary protein.

Can dogs come back from kidney failure?

Acute kidney failure can sometimes be reversed with rapid and intensive vet care. But it's a life-threatening illness and around 30-50% of dogs who develop acute kidney failure won't survive. Dogs who do recover may develop long-term problems, especially chronic kidney disease (CKD).

Do dogs drink a lot of water with kidney failure?

Dogs with kidney failure often drink more water than usual and may need to urinate more frequently. This occurs because the kidneys are no longer effectively filtering waste, leading to excess water loss.

What level of creatinine indicates kidney failure?

There's no single creatinine level for kidney failure; it's assessed with GFR, but levels above 4-5 mg/dL often signal severe impairment, with levels exceeding 10 mg/dL indicating potential kidney failure (Stage 5) needing dialysis, though doctors use GFR <15 mL/min as the key marker. Normal ranges are roughly 0.6-1.3 mg/dL for adults, varying by sex, age, and muscle mass, with higher levels indicating worsening kidney function.
