Why is my dog drinking a lot of water?

Excessive thirst in dogs:

Drinking a lot of water, medically termed as polydipsia, often accompanies some underlying health and medical conditions that compel your puppies to have frequent thirst, which should be evaluated by monitoring daily water intake.

Normal amount of daily water intake:

According to some canine medical associations and pet specialists, normal and standard daily water intake should be 1 ounce per pound of body weight, but this is not for all groups of dogs, like toy, sporting, working, and herding, etc. Daily water intake varies depending upon the working and resting level; athletes and working dogs drink more water compared to toy and companion types. Irrespective of daily intake, water should be provided ad libitum and at all times. Some dogs are habitual in drinking water at night; limiting water quantity may trigger many health issues such as dehydration, digestive problems, electrolyte imbalance, and kidney diseases, etc.

Determination of daily water intake of your puppy:

Here the question arises of how to determine the daily water intake, which becomes even more difficult if you have multiple pets. A separate bowl for each pet should be installed in a specific location within the house; in the morning, fill the bowls with water, and after 24 hours, check the remaining water, for which an easy way is to use a graduated bowl. The modern way is to have microchipped dogs for which only relevant bowls open; this aids in determining differential water intake.

Reasons for excessive thirst in dogs:

There are many causes of drinking a lot of water; some may be innocuous, and some are detrimental to the dog's health and well-being. Some reasons are discussed briefly here.

Dry and seasoned foods:

Giving foods with less moisture content compels them to drink more water because it does not fulfill their water requirement. Seasoned and spicy foods also increase thirst, and dogs drink a lot of water.

Hot weather:

During hot weather water loss increases, and people become dehydrated through evaporation; this causes them to drink more water.

Exercise and working level:

Sports and working dogs need more water, as these activities cause consumption of more water. Active and athletic young dogs drink more water than older ones because of increased activity level.

Age:

Young puppies require more water because their kidneys don’t concentrate urine, and there is loss of water through urination, and also they are active and need more energy and water. Senior dogs require comparatively less water if they are fit and disease-free. Some medical conditions make them less or more thirsty.

Drugs and medicines:

Certain medications like diuretics, anti-seizure medicines, and corticosteroids cause frequent urination and loss of fluid; using such medicines increases thirst and drinking more water.

Medical problems:

Many health issues cause the dogs to drink more water, which may be either kidney-related or not.

Vomiting and diarrhea:

Loss of water through diarrhea and vomiting contributes to the dehydration and fluid imbalance, prompting them to drink more water. Problems in the large intestine cause inappropriate absorption of the consequent loss through feces; this leads to general fluid and electrolyte imbalance. Vomiting is also one of the major reasons for water depletion in the body.

Diabetes mellitus:

This is a condition that develops when the pancreas does not produce enough insulin or the produced insulin does not work normally; it causes an increase in blood sugar level. The body responds to increased sugar levels by eliminating them through the kidneys frequently, which is accompanied by water, leading to thirst and drinking more water. Thirst and frequent urination are the primary signs of diabetes in dogs.

Diabetes insipidus:

This is excessive production of urine due to hormonal changes; kidneys produce large amounts of urine, leading to loss of water from the body; dogs drink a lot of water, which is not fulfilling; and generally victims of this condition face dehydration. Even though the condition resolves on its own, if you are unable to differentiate types of diabetes, a visit to a veterinarian is recommended.

Liver problems:

Bacterial infection of the liver, most commonly leptospirosis, causes excessive urination and thirst. This is due to rodent urine, which may be transferred from ponds or rain puddles. This is vaccine preventable. If your dog is drinking or urinating a lot after swimming in a pond or rain puddles and is also not vaccinated, leptospirosis is to be suspected and should be dealt with without delay, as this is a fatal and dangerous infection.

Hyperthermia:

Fever or increased body temperature compels dogs to drink more water, as this increases loss of water. Fevers can be due to infections, inflammation, immune-mediated diseases, or toxin ingestion.

Renal failure:

Kidney failure is an inability of kidneys to filter waste products efficiently; when kidneys filter toxins, they draw more water with them, causing excessive urination and thirst. Kidney-related issues are of much importance and must be resolved at the earliest to avoid further deterioration.

How to treat polydipsia in dogs:

The first and foremost thing to do is bring your dog to the veterinarian for a general examination and detection of the prime culprit behind this condition. A veterinary doctor may take assistance of urine analysis, bloodwork, abdominal radiography or ultrasound, or specimen culture to spot the exact underlying cause, and then appropriate treatment will be offered.

Vomiting and diarrhea can be treated by antiemetics and anti-diarrheal medications, and hormone deficiency can be replaced by synthetic anti-diuretic hormone to stop excessive urine production. Fever and hyperthermia can be corrected by antipyretics and anti-inflammatory drugs. Cushing's disease, also one of the reasons for drinking a lot of water, can be treated by the synthetic enzyme trilostane, which reduces the production of excessive cortisol.

Conclusion:

There are so many reasons for your dog drinking a lot of water, which range from just an increase in body temperature to severe systemic and organ damage, which are the

signs of monstrous abnormalities within the body. This condition should be properly handled and monitored in order to limit progression to the devastating stage.
