Quick Answer. 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. If a dog is dehydrated, it may also have a dry tongue and gums, be lethargic and exhibit thick ropelike saliva. Illnesses such as liver disease, diabetes, Cushing's disease, diarrhea, fever and infection can also cause dehydration.
Other potential factors behind polydipsia and polyuria are low protein diets, medications that are prescribed for removing excess fluid from the body (diuretics), and age. The younger and more active a dog is, the more likely it is that it will have intermittent increases in thirst and urination.
