not recommended for power-chewer by Libby's mom from NH01/28/2015
my 14 month lab puppy loves tennis balls but is an aggressive chewer. she liked this but shortly grew frustrated trying to remove the tennis ball so she chewed it to bits until the clover-leaf hole was big enough to put her whole face in.
If it were a bit easier to get tennis ball out, it would last longer. The quality is decent, but not for power-chewer.
