So we ordered, and just received, our Air 235 Hero Disc. It's nice...but I think it's too big for Lexi! I think maybe we need a smaller one...maybe the 215 or something?
She has a really hard time holding on to it, even when we roll it. It's big and heavy for her.
Oh well, it was only like $3.
The 215's are what I use. They are perfect for a Sheltie!
