Apparently Chase modeling the stacking box made it very desirable. I’ve been flooded with requests for contact information. John says I may put this on the blog. His web site is www.GrayfootAgility.com There is a contact link on his site or use email@example.com The box teaches muscle memory for conformation and is great for proofing the stand-stay for obedience. Nope, I don’t have stock — just love a useful, well-made product.
