I have a tough 10lb little dog that chews thru kongs like crazy. HE loves his 13" TUG, his decorative 3" Jingle ball (it is listed separately and is $3 on the site--look for it) and his bouncy top from this set of toys. You will LOVE how durable they are, natural rubber and fun! they last!
Love love love these! I have bought every kind of toy you can think of. With three aggressive chewers it takes them 12 months to get these down to nothing. Even better I love the price! I have ordered the rubber bones, ball with bell, and the rings and was very happy. However for the aggressive chewers do not get the Rubber Multicolored Studded Toy or the Rubber Tug (13") both were done in about 30 minutes.
