Possible causes of dog diarrhea and drinking lots of water
The urge to drink a lot of water due to thirst sometimes occurs alongside diarrhea. A dog may experience both diarrhea and thirst as a result of an underlying condition.
Severe thirst and diarrhea in a dog may indicate a disease or a more serious medical issue.
The possible causes of diarrhea and drinking a lot of water are:
Gastrointestinal infection by bacteria, intestinal parasites, or viruses is the most common cause of diarrhea and thirst in a dog.
Gastrointestinal infections can lead to thirst in dogs by causing vomiting and diarrhea, which can result in fluid loss and dehydration.
A dehydrated dog feels thirsty as their body creates the urge to drink lots of water to replace the lost fluids.
Change in diet
A change in your dog’s diet can cause dog diarrhea and drinking of a lot of water due to food intolerance or allergy, an upset stomach, and thirst because of the type of food they eat can affect their water intake and hydration levels.
This is because it takes time for your dog’s stomach to adjust to the new food and a sudden change to a new food may cause diarrhea.
In addition to causing diarrhea, some foods, especially those that are high in sodium, can increase a dog’s thirst and cause them to drink more water.
If a dog’s new diet contains less water content than their previous diet, they may also feel a need to drink more water. For example, if a dog switches from wet to dry food, they may feel a need to drink more water.
To avoid these problems, it is important to introduce changes to your dog’s diet gradually, over the course of several days or weeks, to give their digestive system time to adjust.
Also, it is important to choose a high-quality, nutritionally balanced dog food that meets your dog’s individual needs.
Diarrhea and drinking a lot of water can be symptoms of a wide range of illnesses in dogs, including viral or bacterial infections, gastrointestinal disorders, and systemic diseases.
When a dog is sick, they may experience symptoms such as vomiting, diarrhea, fever, or excessive panting, which can cause them to lose fluids which causes dehydration.
In response to this loss of fluids, a dog’s body triggers thirst to encourage them to drink more water and rehydrate.
Some illnesses may cause a dog’s body to produce more urine, which can also lead to increased thirst in an effort for the body to replace the lost fluids.
A stressed dog also experiences diarrhea including drinking of a lot of water, which may appear at the same time. Stress can come from different sources such as a change in their environment or routine, new people or pets, loud noises, and other fear-related stressful situations.
Stress can lead to thirst in dogs because their body’s response to stress can trigger an increase in fluid loss and dehydration.
When a dog is stressed, their body produces stress hormones which cause an increase in the heart rate and breathing rate, leading to excessive panting and sweating.
This increased panting and sweating causes a dog to lose fluids and become dehydrated. In response to this, a dog may feel the need to drink more water to restore the fluids lost due to stress.
Stress can also affect a dog’s appetite which can lead to behavior changes in their food and water intake. This means a stressed dog may eat less and also drink less water resulting in thirst.
Stress and anxiety also cause a variety of symptoms including pacing, licking, drooling, yawning, crying, barking, and hiding.
Side effects of medication
Medications can sometimes cause side effects in dogs, including diarrhea and drinking of a lot of water which may happen at the same time.
The side effects can occur due to irritation of the digestive tract and allergic reaction which causes diarrhea.
Some medications can cause dehydration or increase a dog’s need to drink water. For example, medications such as diuretics can increase urine production which causes a dog to lose more fluids, leading to dehydration.
Also, certain medications can cause a dog to have an increased appetite and a dry mouth which increases a dog’s thirst sensation, leading to a need to drink lots of water.
Poisoning in dogs can lead to a variety of symptoms, including diarrhea and drinking of a lot of water. This is because many poisons and toxins can cause gastrointestinal upset and also thirst because certain toxins can cause dehydration, leading to an increase in the dog’s need for water.
When a dog is poisoned, their body responds by trying to remove the toxin, which can lead to vomiting, diarrhea, or increased urination.
These symptoms can cause a dog to lose electrolytes and fluids which leads to dehydration. In response to this, a dog may feel thirsty and a need to drink more water to replace the fluids lost due to poisoning.
Some toxins can also cause damage to a dog’s organs, such as the liver or kidneys, which can affect their ability to regulate water and electrolyte levels in their body. This can lead to an increase in thirst as their body tries to maintain hydration.
Dogs may accidentally ingest toxic substances such as household cleaners, contaminated food or water, pesticides, insecticides, poisonous plants or human medications, which can cause diarrhea and other symptoms.
Dog diarrhea and drinking lots of water: What to do and when to seek help
If your dog is experiencing both diarrhea and drinking of a lot of water, it is important to seek veterinary care as soon as possible.
Here are other signs that indicate that you should see a veterinarian immediately:
Severe or bloody diarrhea: If your dog’s diarrhea is severe or if there is blood or mucus in the stool, this could be a sign of a serious underlying condition and requires immediate veterinary attention.
Other symptoms: Other symptoms may accompany diarrhea and drinking a lot of water, such as vomiting. If your dog is vomiting along with diarrhea, this can quickly lead to dehydration and other complications and requires immediate medical attention.
Other symptoms to look out for include lethargy, lack of appetite, breathing difficulties, signs of pain or discomfort, fever, and signs of dehydration, such as a dry nose or mouth and sunken eyes.
Suspicion poisoning: If you suspect that your dog has been poisoned, it is important to seek veterinary care immediately.
If your dog is a puppy or an older dog: Puppies and older are generally more vulnerable than healthy adult dogs so delaying treatment could result in their condition worsening or becoming more difficult to treat. Therefore, it is essential to seek immediate medical care.
