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 🚀🇺🇸
