Excessive drinking and urination in dogs can be alarming—and it’s rarely something to ignore. In this episode, Laura Reeves and veterinarian Dr. Marty Greer take a deep dive into polydipsia and polyuria (PD/PU), breaking down the most common causes, the less common “zebras,” and the critical diagnostic steps every dog owner should understand before restricting water.

Brief Show Notes:

1. Common causes of excessive thirst in dogs: kidney disease, diabetes, Cushing’s
2. Less common (but serious) causes including lepto, hypercalcemia, Addison’s, and psychogenic polydipsia
3. Why urine testing is just as important as bloodwork
4. The danger of restricting water without a full veterinary workup
5. How leptospirosis affects dogs (and people) and why it’s now considered a core vaccine
6. Early kidney disease, protein loss, and why prescription kidney diets matter
7. Practical management tips for “water-obsessed” dogs—after medical causes are ruled out

A must-listen for dog owners dealing with excessive drinking, chronic kidney concerns, or confusing diagnostic results—and for anyone who wants to better advocate for their dog’s health at the vet.
