No doubt, water is an essential component of the body. More than 50% of the body is water. Dogs cannot perform their metabolism without water, and therefore they require enough water to run their body.

According to some research, dogs require two and a half times more water than the food they take. It is a rough count since the actual water needs are variable among every dog. The actual water requirement depends on its daily activity, outside environment, and type of food they take. But on average, they need one ounce of water per pound of body weight.

Technically, it is not wise to measure the exact amount of water for your dog and don't let him drink more than that. It is wise to contact your veterinarian, and he will advise the minimum and maximum intake of water according to your dog's body condition.

If you know how much water your dog drinks in a day and notice a horror increase in the water intake, you should probably call your vet because there may generate serious complications. Indeed, there can be many causes for your dog being thirsty, some are mild, and some are serious. Here are some symptoms you may need to be aware of:


Dehydration can be the most common reason that causes your dog to be thirsty. Environment changing is one of the big factors, the water requirements of winter are less than summer. Just like us, we drink more water in summer to relieve thirst.

Normal level dehydration is acceptable because of the hot weather. However, if your dog doesn't feel enough after drinking a lot of water, there might be a sign of severe dehydration. You need to change your dog's daily routines and diet immediately. Severe dehydration may lead to vomiting and diarrhea, and sometimes your dog may become unconscious.

Your dog might be ill. Many diseases such as diabetes mellites, diarrhea, infection, fever, Cushing's disease, and infection may cause excessive thirst. Dogs suffer from excessive urination in conditions like diabetes mellites which may be the cause of excessive drinking.

It is important to consult your veterinarian to diagnose the disease completely. A proper diagnosis of the disease will lead to a proper solution to excessive thirst.


If your dog is suffering from the disease that needs long-term medication for treatment, those drugs may cause excessive thirst. Furosemide, a heart failure drug, and other drugs that are used to treat seizures, asthma, allergies, and inflammation are also cause the result of excessive thirst.


Dry foods that contain a very low amount of water contents are one of the reasons. Dry foods that contain high sodium are the primary cause of increased thirst. The more your food contains salts, the more your dog feels thirsty. Moreover, large amounts of salts can be poisonous to your dog.

So, your dog's diet should contain enough water contents. For example, using canned foods or proving your dog's raw food, or you can ask your vet for a detailed diet plan for your dog.

Besides solving the diet problem, you should also revolutionize the water feeding behavior. In common, household water may contain excess solutes, which can be the factor in increased thirst in your dog.
