Kidneys have many functions:
The kidney's filtering system is made of thousands of microscopic tubes called nephrons. A kidney can still function if some nephrons are damaged and stop working. However, if they stop working too suddenly for the good nephrons to compensate or if most of the nephrons stop working, kidney failure occurs.
The immediate risk of failing kidneys is that they cannot clear the blood of dangerous toxins.
There are 2 types of kidney failure:
There are many ways for the nephrons to become damaged:
When the kidneys are not removing wastes from the body, your dog will show many signs:
Some additional signs:
Chronic disease progresses over a period of years and can go unnoticed. When signs finally appear, the disease is already advanced. But with proper treatment, some dogs with chronic kidney failure live comfortably for years after diagnosis.
Your veterinarian may perform the following:
Aggressive action must be taken:
If the kidneys are severely damaged, medical treatment will not be able to reverse the condition. But with early diagnosis and aggressive treatment, many dogs will resume a normal lifestyle for a while.
There are more intense treatment options available:
Home treatment for Chronic Failure:
Kidney failure can develop naturallyas the kidneys wear our. Since this happens with age, there is no real preventative measure; it can only be treated.
Ingestion of even a small amount of antifreeze can lead to acute kidney failure and death. It's more common with outdoor pets that are more often exposed to antifreeze.
ARF is a life-threatening condition, with a guarded prognosis.
The prognosis is better if infection was the cause, rather than a toxic substance.
The long-term prognosis for recovery depends on the amount of kidney damage that has occurred, because kidney tissue cannot re-grow.
Your veterinarian will do blood and urine tests during treatment to see how well the kidneys are responding. If there is a positive change within the first 48-72 hours of therapy, there is a good prognosis. If there is no change, the prognosis is weak.
Most cases of CRF progress slowly. Therefore, with proper management, your dog can have a good quality of life for several years.
