Why Do Old Dogs Drink So Much Water?

As our furry companions age, we are often taken aback when their behavior suddenly changes. One common concern that pup parents have is why their old dogs are drinking an excessive amount of water. While there are simple reasons why dogs may need more water, such as hot weather or increased activity, persistent excessive thirst may be a cause for concern.

Reasons Why Healthy Dogs Drink More Water

All dogs, regardless of age, need water to stay hydrated. The amount of water they require can vary based on several factors, including the weather, thickness of their coats, level of physical activity, and diet. So, if you notice your dog emptying their water bowl on a specific day, they may simply be experiencing a normal increase in hydration needs due to these factors. However, if their excessive thirst continues for several days, there are a few things you can do to help:

  • Check the temperature for the day and provide wet towels for your dog to lay on.
  • Regularly brush your dog to remove undercoat or loose shed hair.
  • Limit their exercise time to cooler parts of the day and shorter intervals.
  • If they eat only dry kibble, consider adding some gravy or water to their food.

Reasons Why Unhealthy Dogs Drink More Water

If your old dog is drinking significantly more water than usual, it may indicate an underlying health issue. Excessive thirst is often accompanied by loss of bladder control and accidents in the house. Here are some common conditions that can cause older dogs to drink excessive amounts of water:

1. Kidney Disease or Failure

As dogs age, their kidneys may not function as effectively as they used to, leading to kidney failure. This can be caused by various factors, such as aging, chronic water deficiency, or imbalances in their diet. Additionally, older dogs are more susceptible to urinary tract infections, which can progress to kidney disease if left untreated. Kidney disease results in increased thirst and frequent urination.

2. Cushing’s Disease

Cushing’s disease is common in dogs that have experienced trauma, accidents, or multiple surgeries. It affects the adrenal glands, which produce hormones like adrenaline and cortisol. Trauma or excessive surgeries can cause adrenal glands to become overworked, leading to an imbalance in cortisol levels. Excess cortisol can cause increased urination and thirst. Treatment options include medication or surgery to remove tumors.

3. Diabetes Mellitus

Old dogs can suffer from both type 1 and type 2 diabetes. Type 1 diabetes occurs when the pancreas cannot produce enough insulin. This leads to excess sugar in the bloodstream and frequent urination, resulting in increased thirst. On the other hand, type 2 diabetes is caused by insulin resistance and is often associated with obesity and inactivity. Both types of diabetes can be managed with medication.

4. Diabetes Insipidus

Diabetes insipidus is not related to blood sugar levels like diabetes mellitus. It occurs when there is a problem with producing or storing vasopressin, an antidiuretic hormone that regulates water balance in the body. Without enough vasopressin, the kidneys filter out excessive amounts of water, resulting in constant urination and extreme thirst.

5. Other Health Issues

There are several other health issues that can cause excessive thirst in dogs, including dehydration, liver disease, infections, parasites, vomiting, and hyperthermia. If your old dog is constantly drinking water and urinating more frequently over a period of two days or more, it’s crucial to take them to the vet for a thorough evaluation.

Conclusion

Excessive thirst in old dogs can have various causes, ranging from normal factors to serious health conditions. While some situations may not require immediate concern, persistent excessive thirst should never be ignored. If your old dog is exhibiting signs of excessive thirst, it’s important to consult a veterinarian for a proper diagnosis and treatment plan.
