Reasons for increased thirst could be early renal disease, hyperthyroidism, urinary tract infections, increased salt intake, Cushing's Disease, and diabetes.
Renal disease: Kidney disease isn't detectable on bloodwork until they are 75% damaged, this means that your dog could be in early kidney disease and this may be the cause for increased thirst. You might also notice increased urination and a picky appetite. A urinalysis is important in this instance as it can detect failing kidneys before bloodwork can at about 60% failure. It will also help to determine whether your dog is concentrating her urine. Low specific gravities (concentration) can be a determining factor of kidney disease along with other disorders above including Cushing's Disease and Diabetes.
Please let me know if you would like more information regarding other conditions.
Thank you
