Excessive Thirst in Dogs: What It Means and When to See a Vet

Published on March 11 by Julia

Increased water intake in dogs can be normal in some cases, but excessive drinking (polydipsia) may signal an underlying health issue. If you notice your dog drinking more than usual, here are some possible reasons:

1. Hot Weather or Increased Activity

Dogs naturally drink more water when it's hot outside or after exercise to stay hydrated.

2. Diet and Food Type

Dry kibble diets require more water intake compared to wet food. High-sodium foods or treats can also increase thirst.

3. Medical Conditions

Excessive thirst can be a sign of various health problems, including:\n- Diabetes Mellitus – High blood sugar levels cause increased thirst and urination.

• Kidney Disease – The kidneys struggle to filter waste, leading to dehydration.
• Cushing’s Disease – Excess cortisol levels can cause increased drinking and urination.
• Urinary Tract Infections (UTIs) – Can lead to frequent urination and more water consumption.

4. Medications

Certain medications, like steroids or diuretics, can increase thirst as a side effect.

When to See a Vet

If your dog’s excessive thirst is accompanied by weight loss, lethargy, vomiting, or frequent urination, consult your veterinarian promptly. Keeping track of water intake can help your vet diagnose any underlying issues.
