Introduction
Kidney disorders in dogs can occur from a variety of different reasons, and they can affect dogs in different ways. While kidney disorders have various causes and effects, they are categorized into two classes of disorders: chronic kidney disorders and acute kidney disorders.
Types of Kidney Disease in Dogs
Chronic Kidney Disorder
Chronic kidney disorders occur over a gradual period of time, and it can take months to years until the dog begins to show symptoms of the disorder. Chronic kidney disorders can be caused by physical injury, infections, poisons, or chemicals. This type of kidney disorder can be particularly devastating because the symptoms do not appear until the kidneys are severely damaged. Once symptoms do occur their onset is very rapid. Dogs suffering from chronic kidney disorders may display such symptoms as increase in urination, increased thirst, vomiting, diarrhea, loss of appetite, weight loss, ulcers in the mouth, and depression. While this type of disorder can not be cured, supportive therapies can extend the dog’s longevity and greatly improve the quality of life.
Acute Kidney Disorder
Acute kidney disorders in dogs appear suddenly and generally before the kidney has been damaged. If treatment is provided quickly, permanent damage to the kidney can be avoided. Acute kidney disorders can be caused by snake bites, shock, as a side effect from infections of specific types of bacteria and viruses, and as an effect of exposure or ingestion of some poisonous products such as antifreeze. The symptoms of acute kidney disorder are much like chronic kidney disorder symptoms, but they can also include changes in the urine itself and pain.
If your dog is experiencing any of these symptoms, prompt diagnosis and treatment is essential in order to prevent any further damage to the kidneys. Your veterinarian will perform a series of tests, such as x-rays and blood tests, in order to find out if the kidneys are damaged and to what extent.
