Urine leakage or having «accidents» also
signal problems, either with infection, loss of sphincter control, or another underlying disease.
Some leave the young dog alone too many hours, which either teaches the dog to hold its feces and
urine for too many hours (and getting comfortable with being full and not emptying themselves, and thus never
signaling they have to go potty), or causing health
problems because the dogs aren't relieving themselves frequently enough.
