Durable bone that you can add a spreadable treat to
Color: Blue
Our German Shepherd was 4 months old when we purchased this. She’s going to be 6 months soon. She has been teething really bad. We wanted some way to sooth her pain. This product was just what we needed. We put it in the freezer with some peanut butter in the center on both sides. Once frozen we give to our puppy. She loves it. When we open the freezer she recognizes the ziplock package that it was delivered in which we store it in our freezer. She jumps around until we give it to her. She loves it and it keeps her occupied for a while. It is very durable. I did not notice any smell when we received it. It does not make any noise. The plastic material is safe for animals. To clean I put in the dishwasher. The only reason I did not give it 5 stars is because sometimes the peanut butter gets stuck in it and may need to go through the dishwasher twice which is not a big deal. Or you can hand wash it. I found the dishwasher was best for us. You do not even have to put anything on it, but our pup likes it. I would recommend to others.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!

Durable Great for aggressive chewers
Color: Blue
Will make one whole room smell like fake bacon, but my dogs love it and it’s super strong and durable. I have a lab mixed with rotty and a full lab so it’s a perfect match.

We have a bully that chews through everything, believe it when I say, he loves this n it is still in one piece. Where I put treats in it or not. He’s also able to play tug of war with is brother with this toy. I will be buying additional ones!

Durable, Dogs love it
Color: Red
My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big
