Your pet could be drinking excessively for many reasons. Do not assume this behavior is due to hot outdoor temperatures, as it may be an early indicator of various medical issues.
- Observe if excessive drinking is also accompanied by excess urination. This info will be useful for your vet.
Measure your pet's water intake.
- Provide plenty of water so that your pet's water bowl never runs dry. Measure, in ounces, all the water you leave out for your pet over a 24-hour period. After 24 hours, re-measure the amount remaining and subtract it from initial amount provided.
- Make sure your pet has no access to other sources of water, such as a toilet, water fountain, or other water bowls. Also, make sure no other pets have access to the water you are measuring.
- It is useful to see a pattern of excessive drinking, so repeat these measurements over 2–3 days.
- If your pet drinks more than, or close to, 1 oz (30 mL) of water per pound per day, notify your vet.
- For example, for a dog weighing 15 lb, around 15 oz per day is worrisome.
