12 yr old border collie and urination

Question
i understand she is old and we love her very much. She is urinating all over the
home. she is only on dosaquin and no other meds. Is there any other answer
besides doggie diapers

Answer
I am not really sure what the question is here.
There isn't a lot that can be done for an incontinent dog except have the vet look her over and see if there are some hormones to help her or some bladder control medications such as phenylpropanolamine.
