This is the second set of dics we have bought the last ones lasted 5 yrs our border collies finally got the better of them with teeth marks etc; plus one split down the middle but I think 5yrs is well worth the money and would let everyone know to buy them the Kong which my 1st border collie had was very hard on his teeth ha ha.And was very impressed by them being made in USA.
