Excessive Water Drinking

by Camille
(Powhatan, Virginia)

Our 4 year old GP has always been a big water drinker but this winter has been drinking water excessively. She is a rescue dog and has been with us for almost 3 years now. When we adopted her she was heartworm positive and underwent treatment successfully. She has since been healthy. With the onset of this excessive water drinking she has been tested for multiple conditions including diabetes insipidus and hormone imbalances but everything comes back normal. Of course, she has had a high urine output but her kidneys have been tested and are normal. She has been urinating in the house on occasion as well. Is there any known condition that GP's get that may cause these symptoms?

My rescue 19 month old Great Pry male drinks
16 to 24 cups/day. He's been tested for
EVERYTHING with normal results. I've had
him for two months - was in rescue for about
six months. His food is different, he's getting
a lot more exercise and is outdoors all day.
He also pants a lot - heavy coat and not

I want to thank everyone for their responses.
We did initially treat her for a urinary tract infection. She continues to remain healthy otherwise and perhaps it is not an excessive amount for these dogs. I probably will seek a second opinion just to make sure she is okay.
