For this reason, the tests for GFR need to also assess other factors such as the level of urea and phosphorous. There are other factors which may affect the accuracy of test results. However, just because a dog has elevated creatinine levels, does not necessarily mean there is kidney failure. It is used as an effective test for kidney function in dogs as whatever the cause of renal failure, creatinine levels will be raised. Serum is part of the blood and is measured for creatinine levels in dogs. This is the rate at which the kidney is able to process waste products via bloodflow. Recognizing an elevated creatinine level in your dog is a good way of testing glomerular filtration rate (GFR) of the kidney.

If the dog is older than 7 years of age, they are considered a ‘ senior’ and may even need more regular visits. Taking your dog to the vet for at least a regular annual checkup is imperative. This means damage to your dog may be occurring, even if there are no obvious physical symptoms or behavioral changes.

Unfortunately, even if the renal system is being deteriorated, it can still function well for a long time. We mentioned in the introduction that age is an important factor in vital organ functionality, but a disease, disorder, infection or even trauma can lead to renal failure. The causes of kidney failure, and therefore high creatinine levels in dogs, can be various. If the kidneys are not functioning, it means there is kidney failure.

However, if the levels are too high, it implies the kidneys are unable to process the creatinine adequately. If the kidneys are functioning properly, then there should be a normal level of creatinine in both the urine and blood. However, it can be useful in diagnosing kidney function. It is not particularly useful in itself and, as a waste product, it is processed by the kidneys and excreted via urine. Creatinine is a waste product which is created by the breakdown of creatine phosphate (also known as phosphocreatine) from muscle tissue.
