You can take her in for a check up to discuss options, the vets in our town tell us our one option other than expensive perscriptions, is the antihistamine, in sudafed.
the antigistimine tightens the stuff in their body, and helps them so they are not incontinent.
same thing is in the proin and other scripts, it is best though to take her in, make sure it is not uti or any other thing, like tubes not hooked up properly to the kidney or bladder wich can be seen on xray or ultrasound.
after spay, they can become overweight, so be ever vigilant, you should be able to feel ribs and spine easily.
without pushing into the ribs to feel them.
many think they are fit, when they are not.
anyway, not saying you are one of them.
the thinner she is the easier it will be on her bladder problem,
