I've been working on sit with Anita today. She does it pretty well, but it's hard to make her respond to just a signal, without a treat. At first, she also only seated when I was standing, but then I starting moving around the house and telling her to sit while I was on my knees or sitting on the floor, it has worked well.

We'll have to keep working on this, but I'm sure she'll be a sitting expert soon
