Kidney Failure Affects Pets
By: Michael Lamping, DVM
We all want our pets to live longer, more comfortable lives. Due to improved nutrition and disease prevention, we see many cats and some dogs thrive past 15 years of age. However, as dogs and cats age, their internal organs inevitably show signs of deterioration. The kidneys often decline at such a subtle rate that symptoms progress slowly. When kidneys fail to properly form urine due to damage to the filtering system, normal by-products of the body begin to accumulate in the bloodstream. The stomach, mouth, skin, and muscle are especially affected by kidney failure. Weight loss, decreased appetite, strong thirst, increased urine volume, vomiting, bad breath, unkempt hair coat, and lethargy frequently occur as a result of kidney disease.
At Murphy Road Animal Hospital, we diagnose and evaluate the severity of chronic kidney failure by performing blood and urine analysis, including a test called the urine protein to creatinine ratio. Using the results of these tests, we can better assess the prognosis and formulate an optimum treatment plan. Unfortunately, failing kidneys progressively worsen. Without treatment, many affected pets live less than a year. These pets need supplemental fluids regularly to replenish their body's hydration. With fluids, a prescription formula diet, and other supportive care, pets may live 2-5 years after diagnosis.
The pet food recall (www.menufoods.com/recall
) has affected many pets. The tainting of some brands of soft pouched or canned cat and dog foods with a toxin has lead to sudden onset kidney failure in some pets. Recovery from this type of kidney failure is possible. We have been able to help several affected pets at our hospital.
If you believe your pet is showing signs of decline, be careful not to attribute these symptoms to "just getting old". Rather, visit your veterinarian for an examination and pet health plan.
