KONG Air DogTennis Ball with Squeaker - M

Same as the other rubber balls, lasted two hours before the squeaker stopped working.

Not mediocre: just plain bad! In the past... these balls used to last for months – now, my Dachshunds destroy them in a day, tops. Reduced to pieces! Just avoid them, simple as that.

The balls lasted only 2 minutes, just playing fetch and bringing the ball back. The dog's teeth pierced them really quickly—very disappointing for Kong. I won't buy them again.
