One of my dogs is incontinent and it can happen when she is wide awake! The pills work wonders and we actually weaned her off the pills and liquid, she is now only on high quality food.
Heres an example of what happened one day: We went for a run in the park and she was worn right out! Came home and she was laying on the couch while I was petting her and she emptied her ENTIRE bladder right there on the couch! Poor girl had no idea!
Definatly see the vet, my dog also had a bladder infection and crystals before we got her. Its a problem that can be really easily fixed!
Hope she gets better soon!
