Balls on a rope are a favorite. Balls on their own are so boring
but on a rope they are the best. I think he just likes the rope part, but the ball makes it a better toy (easier to throw and fling around with the added weight). I just buy the green Chuck It balls (the "erratic" ones) and thread a cheap rope through. They also make nice jewelry, if you're into that sort of thing (yes, he did this to himself):
He loves fur tugs from Clean Run, but is terrible about bringing them back. His entire goal is to get them from me and shred them. Frustrating. He just won't retrieve soft toys no matter how much I work on it.
Any stuffed animal is a favorite, but he shreds them pretty fast so they are not a frequent thing. My MIL got him this monkey that plays music and it was his favorite thing in the entire world until he ripped off its limbs and I took it away. I think I need to get one for agility class and see if he'll work for it. Just picture me running around with a stuffed monkey playing the most annoying song you've ever heard.
