I have two male dogs who will pee in the house in less than 10 minutes. After being outside for an hour. If I leash them and tie the leash to lets say, a table, they will not pee even after 6 hours. But if they are unleashed they will pee on the refrigerator, table, couch, etc. I take them out every 4 hours. They are 2 and 3 years old and I am sick of wiping up pee! Help!
