Wow, that little guy is getting sizable. He sure is looking like a fine dog. Frisbees. We buy them online at ±$1.50 each if you get a box of 50. No problem. 5 or 6 times out and we need new ones anyway. Now if they'd catch them with their paws, the frisbees would last indefinitely. If you ever want to go that route, I can send you a link.
