Love, love, love this thing!! It's easy to sneak a variety of small treat products into the little prongs, sturdy enough to hold them there long enough for a 35-pound dog to dig it out. She LOVES this thing -- carries it around even and she's never done that before with a treat-dispensing product of any kind. The little rubber prongs (feels like rubber any way; might be a blend of some kind. Package doesn't say.) From observation of her working to get the treat out it does appear to provide gentle gum stimulation and teeth cleaning without harming teeth, gums, or lips. Package does say to supervise it's use in case it's torn or ripped to prevent a pet ingesting any particles. Package states "Invented in U.S.A." with the business address of Missouri. They are manufactured in China though. Personally I probably would not have purchased it if I had known it was made in China... I'm so leery of those products now. Especially for a pet who cannot verbalize whether good or bad. Just me... My dog loves it and it keeps her busy so I can do things rather than play frequently. That makes it a 5 Star product!!Dog enjoyed but was able to destroy it relatively quickly, I have a 7 month old lab puppy.very small, and the chews did not stay on as shown in the picture. however, that didnt matter because my dog hated them. giving it two stars because she does like to chew on the rubber partIt makes it extra challenging for my dog to dig out the treats and keeps him occupied.My dog had torn this apart before he even had it for a minute. It does not do well with a large dog. He pulled on the points shredding it quickly. It didn't stand up to his bite.Our dog broke this into 3 pieces within 5 minutes of having it. NOT durable as advertised at all. Also, the color dyed his paws and mouth red for the rest of the day. DO NOT get this.Our 7 month old boxer/bulldog has had this about 2 hours and it is pretty much ready for the trash can. I'm not sure who makes these things but they must not have dogs.Disappointed in this. Bought one for a gift and one for my dog. The dogs both chewed them apart (under supervision thank goodness) in a matter of minutes. I will not purchase again.Unfortunately this product I felt was unsafe. I gave it to my 18 month GSD cross who isn't a big chewer as I liked the idea of attaching the treats around the outside. She destroyed it in a short space of time and the plastic teeth broke off easily so for this reason I feel it is not fit for purpose and it's now in the bin. I'll stick with Kongs.Great quality, shame my dog didn't find it very interesting.All good here! Tough plastic lasts a while even with a terrierIt was exactly what I wanted. It has proved to be indestructible so far and is my dog’s favourite toymy boy loves this toy, he chews it a lot and has not damaged it like others toys he has had, good toy well worth the money
