If that dog found a clever way in...the girls might find that same way out. I would walk the yard and find the answer. Sometimes it's not always best to make things simple.
[MENTION=572]Libra926[/MENTION]: I KNOW that dog didn't come under the gate or the wall. I think the kids next door (turns out that's where the dog lives) must have left a chair or something up against the wall that she hopped up on and came on over. It hasn't happened again, so hopefully it was a one time visit. If not, I'll be going over to my neighbors for a chat.
