Dog Health Questions? Ask a Dog Vet for Answers ASAP
Hi there and thanks for your question.
I get very concerned when an older dog starts to drink and urinate a lot. There are a few things that can cause these symptoms.
In an older dog we worry about kidney disease. This can be due to toxin ingestion or a virus called leptospirosis but is often simply due to aging changes in the kidneys.
Diabetes can cause these symptoms as well.
If you girl is not spayed, an infection in the uterus can cause this and is very serious.
There is also a condition called Cushing's Disease that can cause an increase in thirst and urination. This usually also causes an increase in appetite, but as the disease progresses it can cause other sicknesses that reduce the appetite.
You can read more about Cushing's here:

It does sound like she should see a vet and have some blood and/or urine tests done.
I hope she is ok!
