Excessive drinking of water is just one potential kidney disease symptom of many in dogs, and kidney diseases are the second leading cause of canine deaths after dog cancer.
The kidneys are the vital organ responsible for producing urine, and they also act as a sort of filtration system, removing harmful contaminants from the bloodstream.
When the kidneys fail, the body loses these functions and the dogs health drops considerably.
With a type of kidney disease known as renal failure, the presence of failing kidneys will usually cause the animal to produce dilute urine, and their bodies will be contaminated with waste that was left unfiltered due to the organ's loss of function.
Naturally, this is often fatal due to the poisoning of the blood.
In dogs, two of the most common types of dog kidney disease symptoms are chronic and acute renal failure. Chronic renal failure is perhaps the most common kidney disease symptom in dogs, affecting as much as a fifth of older dogs.
This type of kidney disease is usually caused by some other root problem, which is often tied to the dog's age, and so there aren't many specific preventive measures that can actively be taken against it. Acute renal failure, by contrast, is usually the result of the dog ingesting some kind of toxic substance like rat poison, antifreeze or dog poisons.
In general, the symptoms of these afflictions are rather subtle and can go unnoticed for a long time, until the diseases have had time to become more malignant.
Due to excessive consumption of water, a dog kidney disease symptom that might be spotted early on is the production of abnormally large quantities of urine.
But only when renal failure has reached its most advanced stages do the other symptoms become readily visible - often the signs are things like increased lethargy due to their contaminated blood, but it's not uncommon for more physically apparent symptoms to appear, such as a steep drop in the dog's weight, vomiting, an abnormal posture due to pain in the kidneys, and even inability to produce urine at all when dealing with acute renal failure.
Unfortunately, aside from the obvious advice to make sure your dogs stay out of reach of toxic foods that could lead to acute renal failure, there isn't much that can be done to ensure that a pet will never experience kidney disease.
However, there are various forms of dog first aid that can be used to treat some of the conditions. One of the most effective of these is perhaps a full kidney transplant.
However, as can be expected, this type of procedure isn't exactly cheap, and due to its price, it isn't even an option for many people. Still, it often helps to watch the animal's diet, as certain types of dog food can overwork the kidneys by introducing more toxins into the dog's body.
Due to the often-fatal nature of these diseases, it is urgent that you visit your vet to get your pet checked out immediately if you notice even a single dog kidney disease symptom, just to be on the safe side.
