High BUN (Blood Urea Nitrogen) and creatinine levels in dogs, known as azotemia, signal issues with kidney function or decreased kidney blood flow, often caused by dehydration, urinary blockage, kidney infections/disease, toxic injury, severe heart disease, or even a very high-protein diet, with the key being to determine if it's pre-renal (dehydration/flow), renal (kidney damage), or post-renal (obstruction).

What causes elevated BUN and creatinine in dogs?

Increased BUN is most often associated with significant hypovolemia, renal disease, or urinary obstruction and can be found in conjunction with other markers of decreased glomerular filtration (eg, increased creatinine). Clinical signs are associated with underlying pathology.

How to reduce BUN and creatinine levels in dogs?

The most effective way of lowering the BUN is to treat the underlying issues. With kidney disease or dehydration, giving fluids frequently lowers the BUN. With ulcerations/bleeding in the intestines, often antacids or anti-inflammatory medications can help lower the value.

Does high creatinine always mean kidney disease in dogs?

Elevated creatinine levels are usually associated withkidney disease ; however, not all dogs with kidney disease have high creatinine, nor does high creatinine necessarily imply the presence of intrinsic nephropathy .

How long can a dog live with high creatinine?

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.

Kidney Disease in Dogs and Cats: Signs and Natural Solutions

Can creatinine be high without kidney disease?

The opposite can also be true – some people with a “high” creatinine level may not have kidney disease, or it may be less severe than it seems. So, the best way to know how well your kidneys are working is to look at your estimated glomerular filtration rate (eGFR).

What to feed dogs with high creatinine?

High-quality protein: Providing high-quality, easily digestible proteins like chicken, turkey, or fish can help reduce the kidney burden. Omega-3 fatty acids: These can help reduce inflammation and support kidney function. You can find omega-3 fatty acids or fish like salmon and sardines in fish oil supplements.

Does drinking water lower BUN levels?

However, the easiest way to reduce high BUN levels is to make changes to your diet. If you don't have kidney disease and aren't on kidney dialysis, you should make sure to drink more fluids — an isolated rise in BUN while your serum creatinine is relatively low could indicate dehydration.

Can high creatinine be reversed?

When a kidney infection is responsible for high creatinine levels, treatment with an antibiotic should return them to normal. Likewise, if the increased creatinine levels are due to high blood pressure, taking medication to treat this should also lower creatinine levels.

What medications cause high bun creatinine ratio?

Medications: Antibiotics such as tetracycline and corticosteroids used to treat inflammation can increase BUN/creatinine ratio.

What is stage 1 kidney failure in dogs?

Stage 1 Kidney Insufficiency Diagnosis:

Urine Specific Gravity (urine concentration) of early morning sample is less than 1.030. This means the urine is not concentrating correctly 3. Protein is in the urine. If bloodwork is normal, but protein is in the urine, this is a sign of early kidney failure.

What lab values indicate kidney failure in dogs?

Stage 4 CKD includes dogs and cats with severe azotemia (serum creatinine values greater than 5.0 mg/dl). This stage is also called chronic kidney failure and is frequently associated with clinical signs that occur as a consequence of loss of kidney function.

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.

How to lower creatinine levels in dogs naturally?

“A low protein diet is recommended to slow the progression of renal disease in pets,” says Dr. Grzyb, as is a diet that is low in phosphorus, calcium, and sodium. Diets lower in protein and these minerals can help stabilize and even improve kidney enzymes—leading to a healthier pet with a longer life span.

What does dog poop look like with kidney disease?

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.

How to reverse kidney disease in dogs?

While there is no cure for chronic kidney disease in dogs, in many cases the condition can be managed with the assistance of a therapeutic diet, which may help your pet to enjoy a good quality of life for months, depending on their specific circumstances.

What are the three warning signs of kidney disease?

• Urinating more frequently. If you feel the need to urinate more often, especially at night, this can be a sign of kidney disease. ...
• Blood in urine. ...
• Foamy urine. ...
• Persistent puffiness around eyes. ...
• Swollen ankles and feet.

What is the most common cause of high creatinine?

The most common cause of high creatinine levels is kidney dysfunction or disease, as kidneys filter creatinine from the blood, but dehydration, a high-protein diet, intense exercise, certain medications, and muscle mass can also temporarily raise levels, with diabetes and high blood pressure being leading causes of chronic kidney issues.

What foods should you avoid with high creatinine?

Typically, eating large amounts of animal-based protein — found in red meat, fish, shellfish like shrimp, chicken and other poultry, eggs, cheese, and yogurt — can affect creatinine buildup.
