I've been having a hard time fully potty training them because they had free roam of the family room. I could never pin point who was having accidents. At night they have their own crates and sleep well in them. However, during the day, if say I was sleeping from a long shift the night before, rather than crating them I would let them have the family room since I couldn't bear to crate them. I wanted a pen but most are too small for 3 dogs. Someone on here recommended Sea Breeze and I must say I can't be happier!! It's sturdy, they have a variety of sizes and the price was amazing compared to all the others. I've maneuvered it so it can enclose the 3 crates, a pad and food/water bowls. I can still make it larger but I'm trying to keep the area smaller till they're right on with the wee pad!
