hi, my 6 month old pit for some reason pees in the house constantly. sometimes i wonder if she knows she is going to pee, becuase she will pee while she walks. if she knows she has to pee she will walk to the door to let us know. when she was younger she didhave an urinary infection but that is long gone. she also pees about 5 to 8 times a day. any suggesttions on how to help her.
