Not sure yet?
Only have had these for 24 hours but also purchased a couple other chew toys from Amazon as well and all were delivered at the same time. Point being that my #60 silver lab was trading off between all of them and after 2 hours only you can see little shards of plastic sticking up from these chews. Not sure how long these will last before having to throw them away but they are pretty nice and feel heavy and durable. So many of these companies claim they are “indestructible” but all 4 I purchased have little plastic pieces sticking up already. Even my #14 Shih Tzu enjoyed trying to chew these and it kept her busy even though they are for larger dogs.

Golden approved
My golden retriever’s really enjoy these chew toys. They are pretty durable and last awhile. They are hard plastic but they do get rough edges after they’ve been chewed in for awhile
