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.

Durable, Flavorful, Chew Toy
Size: Medium & Large, Color: Red Scorpion
This bacon flavored scorpion shaped dog toy has been a huge hit with my Labrador. The material feels extremely durable and appears to be made from a hard nylon that can stand up to serious chewing. At first, I was skeptical about the bacon scent because I couldn’t smell anything when I opened the package. The moment my dog started chewing on it, though, the bacon scent became much more noticeable. Anyone else who doesn’t smell it immediately shouldn’t worry because it definitely seems to activate once the toy gets some use. My dog is an enthusiastic chewer and has not been able to destroy this toy. Even better, I haven’t seen any meaningful signs of wear, gouging, or damage despite repeated chewing sessions. That level of durability is exactly what I was hoping for. The design also includes areas where treats can be added for extra enrichment, which adds even more value. Most importantly, it has seemed very safe during use, and I haven’t had to worry about pieces breaking off. Overall, this toy has been durable, engaging, and well worth it. My dog loves it, and I love having a chew toy that can actually survive more than a few days.
