One of my dogs has had leakage problems twice in the last 2 years. She is a Husky Shepherd mix going on 12 yrs and about 75 lbs. After blood and urine tests to make sure there was no other indications my vet decided it was a hormonal issue due to spaying as theBCnut suggested. Both times he had her on diethylstilbestrol 1mg for only a short time (less than a month each time). I know it is a hormone supplement and it worked great both times. I do not know what others on the site think of this hormone treatment but it did work. Also it is important they get enough exercise. Good luck with your dog.
