i have a female year and 6 month old pit bull who pees while she is sleeping. she had a UTI in the past a few times but her pee came back clean after everything was taken care of. she either piddles or pees from time to time. she also drinks an abundant amount of water through out the day. my vet told me she probably has a weak sphincter valve. i was wondering if someone can shed some light further on this topic or point me in the direction of a natural remedy or website to buy something along those lines to help tighten it.
