"lasted for a couple weeks with my 8 month old, 20 lb. corgi/aussie mix. After a couple weeks of long and intense fatch games, some tugging sessions, and some old fashoned chewing, he chewed through the center then chewed all the way through the rim. He is a POWER CHEWER in every sense of the word and this lasted longer then some of his other toys so I would reccomend it."
