KONG Whirlz Throw MD/LG

My border collie is usually bored with toys after five minutes, but this one's unpredictable bounce keeps her sprinting across the yard. The durable rubber has survived her aggressive shaking without a single tear.

The whirling action really keeps my dog engaged for longer than a standard ball. It's held up well to some serious chewing so far, though the unpredictable bounce can sometimes send it under the couch.

My dog loves the unpredictable bouncing, but I wish it was just a tad sturdier for her aggressive chewing style. It's held up well for a few weeks of fetch, though.
