Water is vital, but how much is right? Here's a simple guide to how much your dog should drink — and when to worry.
The general rule
As a rough guide, dogs need about one ounce of water per pound of body weight per day. So a 50-pound dog needs roughly 50 ounces. Needs rise with heat, exercise, and dry food diets.

Watch the trends
More important than exact amounts is noticing changes. A sudden increase or decrease in drinking can signal a health problem, so know your dog's normal and pay attention to shifts.
Too little or too much
Under-drinking risks dehydration (dry gums, lethargy). Excessive thirst can signal diabetes, kidney disease, or other conditions. Both warrant attention, especially if sudden or persistent.
Encourage healthy hydration
Keep fresh, clean water available at all times, wash bowls regularly, and add a bowl or fountain if needed. On hot days or after exercise, offer water frequently. If drinking habits change noticeably, see your vet.
