But ...!
He loves it! Even without treats he drags it everywhere around with them, he even sleeps with it! If he throws it in the air, it jumps across the room. The fact that it always rolls in a circle (because of the shape), it can never under beds / furniture disappear.
That's sort of the perfect ball replacement, and our dog loves balls.
I always make peanut butter on the holes and fill it with wet or dry food carrots and rice.
He throws it long then always around until something out tumbles. So not everything is so dirty, you should prefer not to make carpet. We always do it in the garden or on tiles. I also bought two other Kong's something for younger dogs, and they had great fun with it. It is interesting to see, especially as each dog differently approach the thing! It is great fun, zuzugucken the dog with us.
Strong buy recommendation !!!
