I've never had a counter surfing dog fortunately but it seems to me that Tikeya knows she's not supposed to be doing it which is why she only does it when you're not at home. I don't think there really is a way to teach her to stay off as she obviously knows it's wrong already. Dogs have a very hard time resisting temptation as others have said, so I think the only way you're going to get by this would be to remove all food items from your counter tops. You could try the tape idea as suggested also, I've heard that works for a lot of dogs. If all else fails, can you block off the kitchen so that the dogs can't get in there when you're gone with a baby gate or something?
