When kidneys don't function properly, toxins build up in the blood and a dog will become ill. What Causes Kidney Problems in Dogs? Acute kidney failure is an abrupt decline in function that occurs over a period of days. Dogs can develop acute kidney problems as a result of ingesting toxins, including antifreeze, certain medications, tainted foods, etc. Other reasons for this type of kidney failure include decreased blood flow or oxygen delivery to the kidneys, infections and urinary obstruction. While some kidney problems have an immediate cause that can be treated, chronic kidney disease shows up over a period of time and its causes are harder to determine. This condition develops slowly and affects mostly older dogs.
