She wants to drink of water, all the time. When I take her for a walk, either on or off lead, she pee's a lot-way more then a healthy dog should. She will go pee outside, I will bring her in and sometimes 15 minutes later she will either pee on the carpet or need to go out again. However, she can hold it from 11pm-7am out of her crate and never have an accident. I limit her water after 8pm.
She is crated during the day when I'm not home. I have family that is home, and they let her out during the day. Even then, she sometimes has accidents, though this has cut down a lot in the past month.
She has been to two vets. She got a urine analysis done at the first one, and it came back totally normal. She was given a round of clavamox for 14 days. I decided to switch vets, the second vet noticed that her vulva was quite recessed and thinks this may be part of the issue. He wants me to take her for an ultrasound. She is not spayed yet
I guess I just want any suggestions or input before I pay for the $400 ultrasound.

Funny thing is, Bliss the Lab that I bought from a great breeder has never had a single issue in 9 years. Leena, the free dog, has many issues
