Not made for Golden Retrievers.
Nope. Did not last an hour with our Golden Retrievers. We bought these for Christmas hoping to entertain our 2 and 4 year old Goldens while cleaning their teeth. Within an hour they were destroyed.

Dental health
Not a convenient place to place a treat. Then my dog picked not chewed much. Sturdy. Great for a hard chewer.

Poor durability
My 15lb dog destroyed this within a couple hours. He is small but a might chewer. Not chew proof. The end pieces came off easily which could be a choking hazard. He loved it, the idea is good, but it did not last. If you get it, supervise your dog, only allow for short "teeth brushing" chew time.
