Why is My Chihuahua Drinking So Much Water: Is It Beneficial or Crucial?

If you’ve ever shared your home with a Chihuahua, then you know these small but mighty dogs can be full of surprises. From their notoriously spunky personalities to their adorable antics that bring plenty of laughs and joy, there is no denying that Chihuahuas make for entertaining housemates. One particular surprise may leave some owners scratching their heads, though, “why is my Chihuahua drinking so much water lately?”

While it’s normal for any dog to need adequate hydration to remain healthy and happy, the amount consumed by some little Chi pups can often seem extreme or excessive compared to larger breeds. Before worrying about potential health issues, let’s take a closer look at why your pup might have started drinking more than usual.

Advantages of A Dog Drinking A Lot of Water

It’s no secret that dogs need plenty of water to stay hydrated, but did you know that drinking a lot of water can benefit your pup in many ways? Here, we will discuss the advantages of having a Chihuahua drink lots of water. 

💧Maintaining Proper Hydration 

The most obvious advantage to providing your Chihuahua with plenty of water is that it helps maintain proper hydration. Dogs naturally lose moisture through their breath, urine, and feces and need to be replenished to stay healthy.

If you notice that your dog isn’t drinking much water or seems lethargic, it could indicate that they are dehydrated and need more fluids. Ensure you always provide ample fresh drinking water daily, so they don’t become dehydrated.  

đź’§Improved Digestion

Dogs are much like humans in the way they digest food. They need plenty of water to break down food and absorb nutrients. Without adequate hydration, it can significantly hinder digestion.

If your Chihuahua is not getting enough water, he may be at risk for health issues such as indigestion, vomiting, and constipation. Allowing them access to fresh, clean drinking water helps ensure their digestive system works properly. 

đź’§Healthy Skin and Coat

A healthy coat and skin are essential for any dog. Aside from protecting the dog from the elements, a healthy coat and skin also tell us a great deal about its overall health.

Since our canine friends don’t sweat, they rely on drinking lots of water to regulate body temperature and keep their coats shiny and supple. Additionally, it helps flush out toxins that can build up over time due to poor diet or environmental factors.

💧Increased Energy Levels 

When Chihuahuas consume enough fluids, they can absorb more nutrients from their food since it is better digested due to increased hydration levels in their body. It means that your Chihuahua will have more energy, which not only comes in handy during playtime but may also make potty training easier!

Chihuahuas who don’t drink enough may struggle with fatigue or lethargy due to a lack of nutrition absorption from their food sources which can be easily solved by giving them access to fresh water throughout the day. 

đź’§Reduced Risk Of Urinary Tract Infections

One of the most common medical issues seen in dogs is urinary tract infections (UTIs). These infections are painful and can cause discomfort or even more serious complications if left untreated.

Making sure your pup has access to plenty of fresh drinking water throughout the day can help reduce its risk of developing UTIs by flushing out bacteria that could otherwise become lodged in the urinary tract walls. It also encourages regular urination, which is important for proper kidney function. 

Can A Dog Drinks Too Much Water?

You’re aware of the current saying, “Stay hydrated!” That also applies to your Chihuahua. Ensure enough fresh, clean water is on hand, particularly on hot summer days.

It may be essential to prevent dehydration, but it’s possible to go overboard. Many dog owners, as well as some vets, are not aware that having too much water in their dog’s system may cause terrifying symptoms, as well as death.

What is Water Intoxication in Dogs?

Water intoxication occurs when a dog drinks too much water, resulting in a dangerous electrolyte imbalance in its body.

Electrolytes are essential minerals like sodium, magnesium, and potassium crucial for healthy organ functioning. When a Chihuahua is drinking excessive amounts of plain water, it dilutes the levels of electrolytes in its body and can cause them to become dangerously low.

Water intoxication is caused by ingesting large quantities of water over a short period. It can be caused by playing games such as “fetch,” where the dog runs back and forth, catching the ball and coming back for more water each time it returns. It can also occur when dogs drink from puddles or ponds while playing or drink too much after being outside in hot weather.

Signs of Excessive Thirst in Chihuahuas

Chihuahuas are small but mighty creatures and need the right amount of water to stay healthy and hydrated. However, a dog’s excessive thirst can signify health problems like diabetes or kidney disease. If you suspect your pet is drinking too much, watch for these signs that could indicate a problem.

💦Increased Water Intake 

An increased water intake is one of the most obvious signs of excessive thirst in Chihuahuas. If you notice you’re constantly refilling water on your pup’s drinking bowl or pup normally drinks one entire bowl of water per day and suddenly increases its intake to 2 bowls, it might be a sign that something is off.

💦Panting and Drooling 

Another common symptom of excessive thirst in Chihuahuas is excessive panting and drooling. If your pup has been panting more than usual or drooling much more than normal, this could indicate something wrong with their hydration levels.

These symptoms could also indicate other health issues, such as heat exhaustion or diabetes, so make sure to contact your vet immediately if you notice either one. 

💦Increased Urination 

Another sign of excessive thirst in Chihuahuas is excessive urination. Suppose your pup seems to be going to the bathroom much more frequently than usual or producing larger volumes than normal when outside.

In that case, this could indicate that they’re not drinking enough water due to an underlying health issue like diabetes or kidney disease.

đź’¦Weight Loss

If you’ve noticed your Chihuahua losing weight despite eating the same amount of food and drinking the same amount of water, this could be a sign that there is something wrong with their hydration levels. Excessive thirst can lead to rapid weight loss as the pup’s body struggles to keep itself hydrated.

Why is My Chihuahua Drinking So Much Water

While a sudden change in your pet’s water intake can be caused by something as simple as a warm day, it can also signal an underlying health issue. Here are some reasons your Chihuahua may be drinking more than usual.

⭕Heat Exhaustion                                    

If it’s unusually hot outside or there isn’t much air circulation in your house, this could cause your pup to drink more water than normal due to heat exhaustion and dehydration.

Heat exhaustion is especially common among small breed dogs like Chihuahuas because their bodies cannot regulate their body temperature as efficiently as larger breeds. However, all pets should be supervised when the weather gets hot and humid outside.


Dehydration can occur if your pup is not drinking enough water or has been vomiting and/or having diarrhea for several days. It can cause your pet to become lethargic, weak, and dehydrated, leading to increased thirst.

⭕Dietary Changes 

If you just switched up your pup’s diet or brand of food, this could explain the increased water intake. A new diet means different ingredients and different amounts of certain essential nutrients. It can affect how much fluid they need to stay hydrated. In addition, if their food contains more sodium than usual, it can lead to increased thirst.

⭕Illness or Injury 

An increase in water consumption can also indicate some injury or illness in dogs (and cats too). It includes bladder infections, kidney issues, diabetes, and Cushing’s disease.

It’s important to keep an eye on any other behavior changes that could accompany excessive thirst, such as frequent urination or lethargy. These could be signs of a serious medical problem requiring immediate attention from your vet.


If your pup takes any dog’s medication, then this could also be why they’re drinking more water than usual. Some medications can cause side effects such as increased thirst or dehydration and should always be monitored closely by a veterinarian.

â­•Diabetes Mellitus

High blood sugar levels are brought on by diabetes mellitus and result from inadequate or resistant insulin. The kidneys expel extra blood sugar into the urine, which carries water.

In this instance, excessive urine in dogs might result in excessive thirst. Insulin is given to the pup, and the dog’s diet is changed to manage diabetes mellitus.

On the other hand, Diabetes Insipidus is a condition in which the pup’s body cannot regulate its hydration level. This disorder requires hormone therapy and fluid replacement to manage the symptoms.

â­•Urinary Tract Infection

A urinary tract infection (UTI) is caused by bacteria and can increase thirst. If your pup has a UTI, it will experience frequent urination and increased thirst due to the body trying to flush out the bacteria. If you think your Chihuahua may have a UTI, it is important to take them to the vet as soon as possible for treatment.

â­•Kidney Failure

Water conservation is one of the different functions of the kidneys. Both water intake and water loss are necessary for the body to stay hydrated.

The dog’s kidneys have to save water in response to dehydration. It implies that the kidney must handle the extraction of all the substances the body needs to dispose of while utilizing the least water.

A pet whose kidney function is compromised may have trouble concentrating urine and will require more liquid to process the body’s waste products.

How to Stop a Chihuahua from Excessive Drinking

If your Chihuahua drinks excessive amounts of water, there are ways to help it manage this condition.

🛑Identify the Cause of Excessive Drinking 

The first step in understanding why your Chihuahua is drinking too much is to figure out what’s causing their increased thirst. It could be due to several things, such as diabetes, kidney disease, or stress.

It’s important to speak with your veterinarian if you notice signs that your dog may feel unwell. Your vet can accurately diagnose the issue and provide appropriate treatment options. 

🛑Provide Healthy Alternatives 

Once you have identified the cause of excessive water drinking in your Chihuahua, it’s time to take action. Ensure your pup eats a balanced diet of nutritious foods appropriate for their age and size. Feeding your adult chihuahua twice a day with frequent snacks throughout the day would be best. Puppies should eat three times a day with plenty of treats between meals.

Healthy alternatives such as low-calorie treats or small pieces of boiled chicken in the dog’s bowl can help reduce their desire for water. These snacks should only be in moderation and should not exceed 10% of their daily caloric intake. Avoid salty treats as much as possible as well.

Providing plenty of toys that require chewing or licking can also distract them from wanting more water than necessary. 

🛑Proper Hydration Techniques 

Once dietary changes have been made, it’s important to focus on providing proper hydration for your pup. Water should always be available throughout the day but try not to let them drink too much at once. Instead, spread their intake over multiple smaller servings throughout the day (at least 4-6 times).

Also, add ice cubes or frozen fruits like blueberries into their water bowl. Not only will this encourage them to drink more slowly, but it will also provide extra nutrients and flavor!

If you have any concerns about dehydration, contact your vet immediately, as they may recommend electrolyte supplements or other treatments depending on the severity of dehydration symptoms exhibited by your pet chihuahua. 

🛑Creating a Routine 

Creating a routine for your pet is also an effective way to manage their excessive drinking habits. Setting regular meal times and walks throughout the day can help keep them hydrated and provide mental stimulation and exercise, both essential for their overall health and well-being.

Additionally, setting specific times for playtime and potty breaks can help create consistency in their life, ultimately leading to fewer instances of them wanting more water than needed. 

Frequently Asked Questions

How much water should my chihuahua drink? 

The amount of water your Chihuahua needs daily will depend on size, age, activity level, and overall health. However, most adult chihuahuas should drink around one ounce of water per pound of their body weight every day. For example, an 8-pound chihuahua would need around 8 ounces (or 1 cup) of fresh water daily to stay hydrated. Puppies may need even more than that, depending on how active they are!

What can Chihuahuas drink besides water?

Chihuahuas can drink fluids besides water, such as low-fat milk, diluted fruit juices, or bone broth. However, these should only be given in moderation and should not exceed 10% of their daily caloric intake. Also, it’s important to avoid giving your pup caffeinated beverages like soda or energy drinks, as this can cause dehydration.
