If the dog is diagnosed with kidney disease or kidney failure the dog could die within a few weeks to a few months depending on how severe the kidney disease is in the dog.
If the dog gets treatment for the kidney disease then they can live up to 4 years after the diagnoses of kidney disease.
Dialysis for dogs can be pretty expensive although it can help extend the life of the dog and if you have pet health insurance it will usually cover the cost of the dog dialysis treatment as long as the kidney disease happened after you got the pet health insurance.
If the dog has end stage kidney failure they may still die within a few weeks but sometimes the kidney dialysis treatment can help extend the life.
Dogs with kidney failure may have urinary incontinence, Lethargy, loss of appetite, vomiting, weight loss, bad breath and Oral Ulcers.
