This Yak stick arrived a week ago for my 21 week old miniature cockapoo, so the pictures attached are after 1 week of use. I’m pleasantly surprised about how well it’s lasted my teething pup, and its stopped him from destroying my furniture! All other Yak’s I’ve tried from different companies haven’t lasted even half as long as this one as they seem to crumble. This item also arrived 2 days early. Very happy!
