Great product
Flavor Name: Peanut Butter, Size: Medium
I have a very active, medium sized dog (heeler). I wish this product was just a little bigger but it is still a great product. I fill it with pureed meat baby food and freeze. A 2.5oz jar will fill this product about 2 times. This keeps my dog busy for a while. Its also great when she's outside on a hot day. I absolutely recommend this product and at such a great price ($6 when I purchased it) i may buy a few more so I'll always have a frozen one ready when needed.

Extra durable and hard
Flavor Name: Marshmallow & Peanut Butter, Size: Large
Much harder and tougher than most of the chews and bones I get. Too tough for my own dog, but it’s become a favorite of two other dogs in my life who are stronger chewers. Also looks adorable when they carry it around.

Treasured chew toy
Flavor Name: Marshmallow & Peanut Butter, Size: Large
I'm on my 2nd one of these as my dog is obsessed with it! He's a heavy chewers and the 1st one lasted 1 month. Held up pretty well for his strong jaws and he loves it. Great buy!

Dog likes it
Flavor Name: Marshmallow & Peanut Butter, Size: Large
It wears faster on the longer side, my dog does love this, but 2 sides are not chewed as much.
