A puppy is usually thirsty throughout the day, but it might be a warning sign that there’s a problem if it’s excessively thirsty. This condition is known as Polydipsia, and it can also be a symptom of other issues, such as Diabetes, Epilepsy, or Seizure medications. If your puppy’s thirst seems excessive, consider seeking a veterinarian’s advice.
Polydipsia
If your puppy is drinking water at a rate of about four to five gallons per day, you may be facing a medical condition called Polydipsia. This condition results from the kidneys’ inability to concentrate urine. The condition is usually treatable with gradual deprivation of water. Nevertheless, you should always seek medical advice before attempting to cure your puppy yourself.
A dog usually drinks 20 to 40 millilitres of water per pound of body weight per day. This would translate to around three to four cups of water per day for a 20-pound puppy. But puppy is drinking a lot of water amount, this is considered excessive water intake and needs to be checked by a veterinarian. If your puppy is constantly drinking water, it may have other health problems or be simply a sign of normal eating habits.
Diabetes
A veterinarian should be consulted if your puppy is showing signs of diabetes. A dog with diabetes requires insulin injections administered under the skin. A small needle is used to administer insulin, and most dogs tolerate them well. In some cases, a dog may become non-diabetic and no longer require insulin, although this is rare. If your dog has diabetes, regular blood and urine tests and dietary changes are necessary to manage the condition.
Your puppy may be drinking a lot of water. The excess glucose in his bloodstream is absorbed into his body through urine. As a result, the water-filled tissues in his body become dehydrated, causing him to urinate more often. Dehydration and high blood sugar can lead to seizures, coma, and depression in your pup. This condition is a serious concern and requires a visit to the veterinarian as soon as possible.
Why Your Puppy is Whining For No Reason
Epilepsy
Drugs for the treatment of epilepsy in a puppy drinking a great deal of water include bromide, phenobarbital, and potassium bromide. However, some dogs are refractory to these drugs, and the frequency of seizures remains high. New anticonvulsants, such as levetiracetam and gabapentin, may be effective in these dogs.

There are several different types of epilepsy in dogs. The most common type is focal epileptic seizures. However, some seizures may occur without obvious triggers. Seizures in puppies are often more severe than those in older dogs. It’s best to visit a veterinarian early to assess the severity of the symptoms and identify the appropriate treatment options. If the symptoms persist even after the dog is diagnosed with epilepsy, medication is usually recommended.
Seizure medications
A vet may prescribe one of the many anticonvulsants to treat seizures in a puppy. Potassium bromide and phenobarbital are two common anticonvulsants. But they can have unpleasant side effects in some dogs. You can try another medication if one of these medications doesn’t work. A veterinarian may prescribe levetiracetam if phenobarbital and potassium bromide doesn’t work for your puppy. However, you should note that levetiracetam has minimal side effects and is most often prescribed with other drugs.
If your puppy is having seizures, it is important to consult your veterinarian as soon as possible. While it’s tempting to wait until the symptoms go away on their own, if you do, you may have to deal with serious complications. In addition to water, seizures can be caused by poisoning. If you suspect a seizure results from poisoning, visit your veterinarian immediately.
Pedialyte
This type of dog beverage contains a high amount of sugar and is meant to help your puppy replenish the lost water in the body. It is best to give Pedialyte to your puppy slowly for over an hour.
The good news is that Pedialyte for puppy drinking gallons of water is readily available over-the-counter at most pharmacies. It can be found in the medical or children’s aisle, or you can order it online. It is useful for preventing dehydration but should only be used when severe dehydration is suspected. When used as directed, Pedialyte can be given to your puppy if you notice the symptoms of dehydration are severe.
