Long Sit

Wyatt has gone down on his long sit at home a few times when I have gone outside so it's good, in a way.  At least I can reproduce the problem and correct him at home.  I go outside at night so I can see him and he can't see me.  If he goes down, I go in right away, say, "Oops", and put hime back in a sit.  I need to remember to mix in some downs too or he will start coming up on the downs, especially in the winter.  I use a blanket when is is really cold.
