I think you need to first have her get an ultrasound and sterile urinalysis done on her first. After they are spayed they can get urinary incontinence which mine has had since she was spayed. Ours is on 1/4 tab of a 25 mg. Proin once a day. We have had some pee problems but we been staying on top of it. We always have ours get her check ups so maybe the best thing is have that test done. I think there are other meds they can give for incontinence. There are other members that are very knowledgeable about this subject. Susan |
