High quality toy loved by my dogs
Color: Brown, Pattern Name: Tree stump 2 Pack
These are amazing, my dogs favorite toys now. I have two strong chewers who haven’t been able to destroy these. I use yogurt, peanut butter and eggs, broth, really any dog friendly liquids to fill it. I recommend these to all my friends and family with dogs of all sizes.

Excellent Purchase!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
My dogs and I really like these treat toys! I was surprised and questioning whether to keep them when I took them from the box. They are heavier and harder and larger than I envisioned. I didn't realize how hard a nylon/coffee wood combo actually is. However, I want to emphasize that the sales description IS accurate. It details the specifications, materials and size. Clearly states that they are designed specifically for aggressive chewers. I just haven't purchased anything quite like this before.
That said, I was happy it came in a 2 pack and it seems a good value for the price. The dogs have chewed on them, I can see the marks, but they haven't made a dent after about 6 treat sessions. These logs are at least as hard as antlers. They will last a long time. The silicone trays are easy to fill and freeze. I made low calorie popsicles with bone broth and some added mix-ins like pureed pumpkin, healthy freeze dried dog food topper sprinkle, etc. You could also add some peanut butter in the small open end of the log if you want. I just ran hot water over the bottom of the silicone tray to melt the freeze slightly and the frozen treats slid right out. They are shaped perfectly to fit the hole in the log. The seller provided small tools to unscrew/screw the cap in and out for filling with treats.
Even the smaller of my 2 dogs (30 lb Brittany) can get her mouth around the end of the log to carry it to her bed to lay and lick/chew it. I guess another advantage, beyond the durability, of the material is that my dogs don't want to play with it like a toy. They know it is time to relax and have a treat timeout. More like chilling with a chew bone.
Overall we really do love these!! Glad I tried them.

Great Product!
Size: Medium, Color: green, orange, pink, Pattern Name: clean tuff bone bacon
My dogs love their dental chews! This product is durable and the perfect size for each of my dogs. I've purchased two of them (medium and large). One of my dogs is an aggressive chewer and this product is holding up. Hartz makes great pet products. I'm very happy with the product.

Winnie Loves Them!
Size: Medium (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
My Winnie is an aggressive chewer and she loves these bones. They're indestructible and they must be delicious because she works on them every day. I was a bit concerned when they were out of stock for a few months. Please don't discontinue them!
