This thing is AWESOME. Chaco is a PitBull/Rhodesian Ridgeback mix. Safe to safe - he is a CHEWER!! His first WestPaw toy was the Bumi - he adored it. But he got the ends chewed off in about a week or so. He has been slowly whittling it down over the last year. I saw the Tux and thought we would give it a try. I think what makes it perfect is that it's the Zogoflex design - but solid end pieces. He can chew and chew but because he can't get his jaw around it - it's holding up and he loves it!! He tried to use it like a tennis ball but it doesn't quite have the same 'bounce' lol.
We are a West Paw family now and love your product!!
