I have been looking for a bed to have outside for Schatzi. One that is waterproof, especially. I found this one on the Bed Bath and Beyond website and think I will order it. She loves being outside now that we have the porch and the patio area. This should be perfect for her and I think the small size should work just fine,

That's an interesting bed. I'll have to check it out for the Hunter.
