Hi,
My yorkie had pee problems and has drank alot of water, I took her to the vet and he ran tests and said she had cushings disease. This was 4 years ago I am not sure about the age cushings can attack, but keep an eye on your baby if she drinks alot more over than a normal time span please ask about the cushings! I don't mean to scare you, it can be she's a thirsty little girl.
update: cushings only attacks older dogs (tilly was 6 years old) now 10
so please forgive me if I had cause you any alarm.
tilly's & sami's mom
