Dogs can exhibit signs of
excessive water drinking for a variety of reasons, including life - threatening dehydration, illness, side effects to medication, diet and physical activity, according to WebMD.
Primary polydipsia is used to
describe excessive water drinking that is not due to illness or psychosis: bored puppies or water loving breeds may tank up on water occasionally or consistently.
This behavior may include pacing, panting, drooling or
excessive water drinking.
