I'm sorry to hear that Lili is having these problems.

I really do get concerned when a dog has a sudden increase in thirst and urination.

There are several possibilities. One possibility is that she has gotten into something that is toxic to her kidneys. Some examples would be certain plants, or possible antifreeze, or even an organism called leptospirosis which can be spread from drinking from puddles where a skunk or raccoon had been nearby. In any of these situations there is damage to the kidneys and then they release too much fluid. In return the dog becomes very thirsty.

Another possibility is diabetes. A diabetic animal has too much glucose (sugar) in their system. The glucose causes more urine to be drawn into the bladder and then the animal ends up being thirsty.

If this has been a gradual increase and if it is combined with an increase in thirst, a disease called cushing's disease is possible.

Is she spayed? If not it is possible she has a condition called pyometra which is a serious infection in the uterus. This is most common within 1-2 months of having a heat cycle. This is a very serious condition and the treatment is to have her spayed right away.

Some female dogs as they get older can have problems keeping their bladder closed when they are relaxed and can leak urine when sleeping. This is easily controlled with medication. However, this is not a condition that would cause an increase in thirst.

I would highly recommend a vet visit. All of these conditions are treatable but for many, the longer we wait the more serious the condition becomes.

I really hope everything is ok!
