I just bought my 6th and 7th zogoflex. We've got two 80 lb weims. Only the 8 year old female likes toys, but she is totally obsessed with the Zogo. We get two at a time and it takes about 2 years for her to destroy one. Absolutely amazing considering she'll shred a black kong in a matter of minutes. We don't even participate in the return policy, because after two years of playing, I think we've gotten our money's worth. The Zogo is worth absolutely every penny, probably more.
