The product itself looks great and is clearly very well made but my dog had zero interest initially in this which I find odd because many other similar toys she has attacked. Update —- several weeks later all of a sudden my dog decided she liked this and started chewing on it and has been her favorite - go figure Update 2 — it’s become her favorite chew and she’s obsessed with it! My older dog started chewing on it, and it broke one of her old teeth!

It’s half the size of the last one that I purchased. It’s hard to tell from the pictures sometimes.

Should always check the dimensions of items because the pictures can mislead you sometimes The bonus is a great product. It lasts a long time and it doesn’t break. I give this product five stars excellent but the size I purchased is for a smaller dog. Best Bone is what Wakanda growled. Thanks everybody 🚀🇺🇸
