Why Is My Senior Dog Drinking a Lot of Water?

Have you noticed that your senior dog has been drinking a lot of water lately? Depending on the cause, this can be a serious concern or one that’s easily remedied. Here are some reasons your old friend might suddenly be thirsty, including when you should take them to the vet:

It will develop over time.

If you notice your senior dog is drinking more water than usual, don’t panic. This is a common issue and can be caused by several conditions. Your veterinarian will need to do some tests to determine the cause of the increased thirst, but it’s important that you are aware of some possible causes so that you can discuss them with your vet.

  • Kidney disease: If your senior dog has been diagnosed with kidney disease, his or her kidneys may not be able to function properly and regulate water levels in the body as well as they once did. In this case, it is likely that there will be other symptoms associated with kidney failure such as excessive urination (pottying), weight loss, vomiting and low energy levels.
  • Diabetes: If your older dog has diabetes it means their blood sugar levels are too high for them to use insulin efficiently anymore—which means it could have an impact on how much water they need throughout the day!
  • Urinary tract infection (UTI): An infection anywhere along your pet’s urinary tract could also lead them to drink more water than normal because bacteria irritates their bladder walls and makes them feel like they have to go frequently—so this would explain why they might suddenly find themselves needing an extra bowlful daily! While UTIs aren’t normally dangerous if caught in time (meaning when symptoms first start showing up), if left untreated they could become life threatening if allowed spread into other areas such as kidneys or liver tissue.”

It is a signal of something serious.

Your dog may be drinking more water than usual if he or she is experiencing some serious health issues. If your senior dog has been exhibiting these symptoms for a few days, it’s time to make an appointment with the vet:

  • Kidney failure
  • Diabetes
  • Tumors
  • Liver disease (see also: liver failure)
  • Thyroid disease (see also: hyperthyroidism and hypothyroidism)

It is likely due to medication.

Most of the time, high water consumption is caused by medications. Diuretics are often used to treat heart failure and other cardiac problems; however, they can also cause your dog to drink more water than usual. NSAIDs (non-steroidal anti-inflammatory drugs) such as Rimadyl and carprofen can lead to increased drinking as well. Steroids are a third category of medication that can cause your dog’s thirst level to rise. Antidepressants may also increase the amount of water being consumed by your senior dog if he or she is taking them alongside another type of prescription medication.

If you think your aging pet’s increased thirst might be caused by something he or she has been prescribed by his veterinarian, talk with the vet about this side effect so they can help find ways for you both to deal with it!

It does not signal a problem.

  • Your dog may just be thirsty.
  • Your dog may be stressed out and needs more water, particularly if he or she is a puppy and has been teething recently.
  • Your dog may have a urinary tract infection (UTI). If you notice that they have to go frequently to the bathroom, then this could be the cause of their increased thirstiness. It’s important to note that UTIs can also be caused by other things like cancerous tumors or stones in the bladder, so this is something you should bring up with your vet if your dog continues drinking lots of water after any home remedies have been tried!
  • Dogs can get sick from viruses that make them feel very ill—and result in increased thirst! When we humans get sick we drink more liquids because our bodies need more nutrients from food when fighting off an illness, but dogs don’t necessarily eat more when they’re sick (or at least not enough for us humans to notice). This means that when our dogs get sick we might see a lot of extra drinking on top of normal behavior.”

Your pet might have a tumor or a kidney stone.

If your dog is drinking an excessive amount of water, but otherwise seems to be healthy and happy, there may be a tumor or kidney stone. These are serious conditions that must be treated by a veterinarian immediately. Typically, when a dog has one of these conditions they will start urinating more frequently, which can also lead to increased thirst.

If your pet is experiencing any of the symptoms listed above, bring them in for an exam.

Your pet has cataracts.

Cataracts are caused by the clouding of the lens of a dog’s eye. This can be due to age (senior dogs), genetics and trauma. They can be treated with medication, prevented through early detection and removed or replaced if necessary.

In addition to being more common in older dogs, cataracts may also result from obesity, diabetes mellitus and hyperthyroidism—all conditions that make keeping your pet healthy more challenging than usual.

Your pet is diabetic.

Your dog may be diabetic if he has any of the following symptoms:

  • Excessive thirst. If your pet is drinking more than usual, it could be a sign of diabetes.
  • Frequent urination. If your pet is urinating frequently, especially at night and in the morning, it may be a symptom of diabetes.
  • Weight loss despite increased appetite and/or reduced activity level. To test for diabetes in dogs, you can purchase a glucometer to check their blood sugar levels at home or take them to the vet for testing (it’s often cheaper). There are two types of diabetes that affect canines—insulin-dependent and non-insulin dependent—which require different treatments depending on their severity; however, both types can lead to blindness problems as well as kidney failure if left untreated

It needs to be checked by the vet immediately.

If your dog’s water intake has increased by more than 25 percent, it could be a sign of something serious. It’s important to see a veterinarian immediately. If your dog is drinking an unusual amount of water, it may have a urinary tract infection, diabetes or even cancer.

Often, it’s nothing to worry about, but your dog may need to see the vet soon if you’re concerned its drinking too much water.

If you’re worried about your dog’s excessive water consumption, it’s a good idea to see the vet. The vet can run some tests to check for diabetes or kidney issues that could be causing the thirst. They’ll also search for tumors or other health problems that could be affecting their thirst levels. If your dog has cataracts or glaucoma, they may need special medication or surgery to help them drink less water and keep their eyes healthy.

The sooner you get in touch with the vet, the sooner they can begin treatment and get your pet back on track!
