Spoke to Mom this evenin' & she sez that ol' Mizzer White Coat thinks that b/c this was a 'one time' thing, ol' Sara either:

1) passed a small stone ~or~
2) the gage to her bladder was on FULL and she didn't tell anyone/didn't wanna go outside, so she dribbled a bit

She's fine now--still as playful and *bOuNcY* as ever & no leaks!

Thanks for everyone's concern!
