The place we attend for Agility has recently started carrying this item. Saturday morning, Willy and I attended our first Agility clinic, with Lisa Bonker. She also recommends this product, and we got to try it. It is a 'lotus' ball. You put the treats inside, it seals with velcro. You toss it as the dog completes the obstacle, this keeps the dog in drive mode. No treats on the floor, so you don't encourage 'vacuuming.' You open the velcor and the dog eats the treats inside.

The link is for the small size, which I need for my bichons. Also comes in medium and large sizes.
I was able to try it at the clinic -- which was training Discriminations. I like it for Willy and will be getting one. I know Riley will love it! Willy caught on to how it works quickly, and refused to leave Lisa to work with me, ha haaa, so she had to hand it to me so we could practice what we were learning.
Thought I'd pass it along for folks to consider on here.
