Good for independent play
Works well to firmly hold treats in place while your dog chews it/keeps them from choking when it gets too short to hold with their paws. Our dog is 9lbs so his strength may not fully test the durability of the holder...his friend who is about double his size was able to pull out a bully stick from the holder.

Great, except for the edible one
Flavor Name: Chicken & Original, Size: X-Small
My elderly dog and my puppy both love these bones. They are 9lbs and 4.5lbs respectively and this is a good size for them. They also like the next size up and it is manageable for them as well. The only gripe I have is the edible one, it comes apart in larger chunks (that are still very hard) and my dogs swallowed a few before I noticed how large the pieces were. I decided to throw that one away. Its been over a week and no negative side effects so maybe just me being overly cautious. For the price (gold box) just the other two bones were worth it. They last pretty much forever for my dogs, and I would say they are moderate chewers. 4 stars due to the issue with the edible bone.
