@elbrant That's how all my 8-some learned to catch.
If food dropped on the floor - you lost it ! So they all stood on their hind legs and it was like feeding a nest of fledgling sparrows. A gentle toss of the treat and someone caught it !
I saw the DNA kit in an Orvis for Dogs catalogue (you can't spend more money for a dog than with Orvis!) and in at least one other as well. I'm sure you can find one via the internet! Good luck,.
