I have a yellow lab we rescued from hurricane Katrina. We got her in November and have been trying to break her potty problem since. She is 1 1/2 years old and seems to know that the outside is for "doing her business". She has never popped in the house, but we have a problem with her peeing in the lower level family room. She can be left alone for up to 6 hours and not pee anywhere, (we gate off the lower level) but if we forget to let her out every two hours when we are home she will sneak downstairs and pee. I have restricted her acess to the family room, and that seemed to help, but with four kids ages 8,6,4,2 they often forget and leave the gate open. There are times when we have just let her out and 20 minutes later she has peed. The problem is, she is rarely every caught in the act. I was told it doesn't do any good to scold them if you don't catch it right away. She has no signal to tell us she needs to go out, although she has learned to bark to come in. What can I do next to help her?? or at least get her to give me a signal that she has to go outside to pee. Help
