I she eating drinking and acting fine besides the pee pee incidents??
All I can tell you is my experiance with my Bella. (Great name by the way

)
ANyway, she relates going pee to treats...so she asks to go outside whenever she wants a treat. SHe hikes her leg, so she goes out and hikes her leg and does the bucking thing....then runs insode and wants a treat! Im thinking holy crap she does this like every half hour (even worse to my hubby) So I started going out with her, and she isnt peeing at all...she is faking to get a treat! Have you actually seen the pee or is she just squatting so you assume she is peeing? Could she be kidding you???
