Why is my 5-year-old dog suddenly having accidents in the house?
With sudden accidents, it is always best to schedule a vet checkup first to rule out any underlying issues such as infection, GI upset, neurological or muscular issues, etc.
if she checks out healthy, it may be that something has startled or upset her,
especially if this was the same time last year that she had accidents last, causing her to have accidents inside instead of going out. You may need to temporarily revert to a "puppy" style of potty training again, just to get her back into the routine of going outside until she is more comfortable with whatever caused the accidents to start. Using enzymatic cleaners on any accidents can help discourage her from going there again, and making sure to offer some exciting treats and praise when she does go outside may help speed up the process.
