This is Zephyr's first time seeing it. I was really happy with how he went right at it. He likes to use his paws and nose.
Astro was game from the start too. My click was late and then he didn't find his treat, but he continued. I first saw this puzzle done by the Greyhound Carly, with Joan Malak. Astro is related to Carly and I think it's neat that Astro used his mouth to lift the blocks like Carly.
