Why Is My Old Dog Drinking So Much Water? Top Causes

Is your senior dog emptying their water bowl faster than ever? Are you noticing them asking to go outside to pee much more often? This might seem like a simple change. But often, a big increase in how much an old dog drinks is a sign of a health problem. This symptom, called polydipsia (excessive drinking older dog), happens when your dog’s body is trying to deal with something wrong inside. A vet check senior dog thirst is always a good idea when you see this change. It is one of the common Causes of excessive drinking in dogs, especially as they get older.

What is Too Much Drinking? Defining Polydipsia

Dogs need water, just like us. It keeps their body working right. But how much is normal?
Most dogs drink about 1 ounce of water for each pound of their body weight per day.

• A 10-pound dog might drink about 10 ounces.
• A 50-pound dog might drink about 50 ounces.

This is just a rule of thumb. It can change based on:

• How hot it is outside.
• How active your dog is.
• What kind of food they eat (dry food makes them thirstier).
• Some medicines they might be taking.

So, what counts as excessive drinking older dog? It’s when your dog drinks much more than this usual amount. Vets often say it’s too much if your dog drinks more than 2 ounces per pound of body weight per day.

Maybe you haven’t measured it. That’s okay. Just seeing a big change is a sign. Signs of Senior dog increased thirst can include:

• Emptying the water bowl much faster.
• Wanting water right after coming inside.
• Trying to drink from toilets or other water sources they didn’t use before.
• Asking for water more often.

When your dog drinks a lot, they also pee a lot. This is because the body has to get rid of the extra water. So, Dog drinking and peeing a lot often go together. This pair of symptoms is a key sign that something is likely wrong.

If you see your old dog drinking and peeing a lot, don’t wait. Talk to your vet.

Why Older Dogs Drink More: Possible Health Issues

As dogs get older, their bodies change. Just like older people, senior dogs can get certain health problems. Many of these issues can make them drink more. It’s the body’s way of trying to fix things or flush out bad stuff.

Here are some of the top reasons for polydipsia senior dogs:

Kidney Problems (Renal Disease)

Kidneys are super important organs. They filter waste from the blood. They help the body keep the right amount of water and salts.

In older dogs, kidneys can start to wear out. They don’t filter as well. They also have trouble holding onto water. This means the dog loses more water when they pee.

To make up for lost water, the dog drinks more. This is a main reason for senior dog increased thirst.

Symptoms of kidney disease in dogs include:

• Drinking much more water.
• Peeing much more often or peeing larger amounts.
• Losing weight.
• Not wanting to eat as much.
• Throwing up.
• Bad breath that smells like chemicals or pee.
• Looking tired or weak.

Kidney disease can be managed, especially if caught early. A Vet check senior dog thirst is vital to test kidney function.

Diabetes Mellitus

Diabetes in dogs is like diabetes in people. The body has trouble using sugar (glucose) the right way. This is usually because the body doesn’t make enough insulin, or can’t use the insulin it makes.

Sugar then builds up in the blood. When blood sugar gets too high, it spills into the pee. The sugar takes water with it. This makes the dog pee a lot.

Because they pee out so much water, they get very thirsty. They drink a lot to replace the lost water.

Signs of diabetes in senior dogs include:

• Drinking a lot of water.
• Peeing a lot (Dog drinking and peeing a lot).
• Losing weight even though they are eating normally or even more.
• Acting very hungry.
• Lacking energy.
• Sometimes, cloudy eyes (cataracts).

Diabetes needs careful management with insulin and diet. Getting a diagnosis quickly is important for your dog’s health.

Cushing’s Disease (Hyperadrenocorticism)

Cushing’s disease happens when a dog’s body makes too much of a hormone called cortisol. Cortisol is made by small glands near the kidneys called adrenal glands.

Too much cortisol causes many problems in the body. One big effect is on how the kidneys handle water. Too much cortisol makes dogs pee out more water than they should.

Just like with diabetes or kidney problems, peeing more leads to drinking more to stay hydrated.

Cushing’s disease dog symptoms can be many. They often include:

• Drinking a lot of water.
• Peeing a lot (Dog drinking and peeing a lot).
• Getting a pot-belly look.
• Losing hair, often on the body but not the head or legs.
• Having thin skin that bruises easily.
• Panting a lot, even when resting.
• Acting more hungry.
• Losing muscle strength.

Cushing’s is a complex disease. It needs specific tests to diagnose. Treatment often involves medicine to control the amount of cortisol.

Urinary Tract Infections (UTIs)

A urinary tract infection is when bacteria get into the bladder or other parts of the urinary system. This causes swelling and pain.

While UTIs are common in younger dogs too, older dogs can get them. A UTI can make a dog feel like they need to pee more often, even if there’s not much pee there. The irritation can also sometimes lead to increased thirst, though peeing issues are the main sign.

Sometimes, dogs with UTIs drink more because their body is fighting the infection. Or they drink more simply because they are going to the water bowl more often after failed attempts to pee.

Symptoms of Urinary tract infection dogs include:

• Trying to pee more often.
• Peeing only small amounts, or trying hard but nothing comes out.
• Having accidents in the house.
• Licking their private parts more than usual.
• Peeing might look cloudy or have blood in it (hard to see sometimes).
• Drinking a bit more water.

UTIs are usually treated with antibiotics. They are often simple to fix, but they need a vet visit to diagnose and get the right medicine.

Other Causes of Excessive Drinking

Besides the main ones, other things can cause polydipsia senior dogs. These are also important to check for.

• Liver Disease: The liver helps clean the blood and makes important substances. If the liver isn’t working right, it can affect many body processes, including thirst control. Liver problems can cause increased thirst, weight loss, poor appetite, and yellowing of the skin or eyes.
• Electrolyte Imbalances: Electrolytes are salts and minerals in the body. Things like too much calcium (hypercalcemia) can make a dog drink and pee a lot. Hypercalcemia can be caused by different issues, including certain types of cancer.
• Addison’s Disease (Hypoadrenocorticism): This is the opposite of Cushing’s. It means the adrenal glands don’t make enough hormones. While often causing lack of appetite and weakness, it can sometimes affect water balance and cause increased thirst in some cases, though it’s less common than with Cushing’s.
• Certain Medications: Some medicines can make dogs drink and pee more. The most common are steroids (like prednisone). Medicines for heart problems or seizures can also have this effect. If your dog started a new medicine and then started drinking more, tell your vet.
• Diet: Eating very dry food can make a dog thirstier than eating wet food. Eating very salty treats or human food can also cause temporary increased thirst. However, a sudden, big increase is unlikely to be just diet unless there was a major, recent change.
• Dehydration: If a dog hasn’t had enough water for a while, they will drink a lot when they get access to it. This is normal catch-up. But ongoing dehydration might point to an underlying issue causing them to lose too much water.
• Psychological (Behavioral) Polydipsia: Rarely, a dog might drink too much out of stress, boredom, or just habit. This is less common as a sudden, major change in older dogs compared to medical causes. It should only be considered after a vet rules out all physical problems.

These are some of the main Causes of excessive drinking in dogs. Because there are many possible reasons, and some are serious, a vet visit is always needed.

When to Worry: Seeing Your Vet

Anytime your old dog starts drinking a lot more water than normal, you should call your vet. This is not a symptom to ignore or just put down to “getting old.” Senior dog increased thirst is a sign their body is struggling with something.

Seeing a vet quickly is important for several reasons:

• Find the cause: Only a vet can figure out exactly why your dog is drinking more.
• Start treatment: Many of the causes (like diabetes, UTIs, even kidney disease) can be managed or treated, especially if caught early.
• Prevent worse problems: Waiting can let a treatable issue become much harder to manage.
• Improve quality of life: Getting the right diagnosis and treatment helps your dog feel better. They will be more comfortable if their thirst and peeing are under control.

Don’t limit your dog’s water before seeing the vet, unless your vet tells you to. If they are drinking a lot, it’s likely because their body needs that water due to a medical issue. Limiting it can make them sicker.

When you talk to your vet, be ready to tell them:

• Exactly what you’ve noticed (how much more drinking, how much more peeing).
• When it started.
• Any other symptoms you’ve seen (weight change, change in appetite, behavior changes, panting, etc.).
• What food your dog eats.
• Any medicines or supplements your dog takes.

This information helps your vet figure out what might be going on.

What Tests Might Your Vet Run?

To find out why your senior dog has increased thirst, your vet will likely do some tests. These tests help them see what’s happening inside your dog’s body.

• Physical Exam: The vet will look at your dog overall. They will check their weight, listen to their heart and lungs, feel their belly, and look at their eyes and mouth. This can give clues.
• Blood Tests: A small sample of blood is taken. This is very useful.
  • A Complete Blood Count (CBC) checks red blood cells, white blood cells, and platelets. It can show infection or anemia.
  • A Blood Chemistry Panel checks things like kidney values (BUN, Creatinine), liver values, blood sugar (glucose), and electrolytes (like calcium, sodium, potassium). High sugar points to diabetes. High kidney values point to kidney disease. High calcium needs more investigation.
• Urine Tests (Urinalysis): You might need to collect a urine sample (or the vet can get one).
  • This checks if there’s sugar in the pee (a sign of diabetes).
  • It checks for signs of infection (white blood cells, bacteria).
  • It checks how concentrated the urine is. Thin, watery urine when the dog is drinking a lot can point to kidney problems or hormonal issues like Cushing’s or Addison’s.
• Specific Tests for Certain Diseases:
  • If the vet suspects Cushing’s disease, they will do special blood or urine tests that measure cortisol levels after giving certain medicines or at specific times.
  • If kidney disease is suspected, they might do a urine protein test or image the kidneys.
  • If diabetes is diagnosed, they might do a test called Fructosamine, which shows average blood sugar over the past 2-3 weeks.

These tests, combined with the vet’s exam and what you tell them, help them pinpoint the cause of the excessive drinking older dog problem.

Caring for a Senior Dog with Increased Thirst

Finding out why your dog is drinking so much is the first step. The next is caring for them based on the diagnosis.

The most important thing is to follow your vet’s plan exactly.

• Medicine: Give any prescribed medicines on time and as directed. For diabetes, this might be insulin shots. For Cushing’s, it’s specific pills. For UTIs, it’s antibiotics.
• Diet: Your vet might suggest changes to your dog’s food. Special diets can help manage kidney disease or diabetes.
• Water Access: Always provide fresh, clean water. Unless your vet tells you to limit it for a specific reason (which is rare and usually only for short periods under strict watch), your dog needs access to water, especially if they are losing a lot by peeing.
• Monitoring: Keep an eye on your dog. Are they still drinking and peeing a lot? Are other symptoms getting better or worse? Tell your vet about any changes.
• Regular Vet Visits: Depending on the condition, your dog might need frequent check-ups and blood tests to make sure the treatment is working.

Taking care of a senior dog with a chronic condition requires dedication. But managing their symptoms, like polydipsia senior dogs, makes a big difference in their comfort and happiness.

Living with a Dog Who Drinks and Pees More

Even with treatment, some conditions might mean your dog continues to drink and pee more than they used to. This can be challenging, but manageable.

• More Potty Breaks: Plan for more trips outside. This might mean first thing in the morning, last thing at night, and several times in between. If you work, consider a dog walker or setting up a safe potty area outside if possible.
• Managing Accidents: Accidents can happen, especially overnight or if you’re not home.
  • Use absorbent pads in their favorite resting spots.
  • Consider pet diapers for inside the house, especially at night.
  • Use enzymatic cleaners to clean up accidents completely. This helps remove the odor so your dog isn’t drawn back to the same spot.
• Protecting Furniture: Use washable covers on furniture where your dog rests.
• Patience is Key: It’s not your dog’s fault they are having accidents. They likely can’t help it due to their health issue. Be patient and understanding. Scolding them won’t help and can cause stress.
• Easy Access to Outdoors: If you have a fenced yard, consider adding a dog door if your dog is able to use one safely. This lets them go out as needed.
• Nighttime Routine: Take your dog out right before bed. Some people also set an alarm to take their dog out overnight if needed.

Living with Dog drinking and peeing a lot requires adjustments to your routine. But seeing your dog more comfortable and healthier because their condition is being managed is worth the effort.
