Why is my dog drinking and peeing excessively after diarrhea?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Female | unspayed | 9 years old | 95 lbs

Dahlia eating boiled chicken no treats urinating a lot. Still drinking too much water. Our vet prescribed Metronazide for ten days for diarrhea. Why is she so thirsty? She has been off Cephalexin for over two weeks.

If she is drinking a lot of water and urinating a lot this can be a sign of an underlying disease - number one would be diabetes. Did your vet do any blood testing? If not, I suggest you have that done now. The other option, if she is not spayed, is a pyometra (uterine infection). Again, bloodwork would reveal this as she would have a very high white blood cell count. Please take her back to the vet for some blood testing.
