Older dogs, as with older people, they lose the ability to control their bowels & bladder. I don't know if that might be the problem
with Myndi or not. Every thing Freedom suggested is good to consider, more walking around to stimulate the natural function, if she
is capable to walk more, it might help.17 yrs in dog age equals how old in humans? I hope you find something that helps. Must be
a pain for you and for Myndi if she thinks she's done something wrong.
