I tried to find the best treats I could. I wanted them to be made in the USA, I wanted to keep cereals to a minimum, and I wanted meat to be a significant ingredient. It's even better that the two dogs like them, and guard them from each other. I will buy this product again.These are a fantastic option for dogs who chew through things quickly. They take ages for them to tackle. I purchased largest size for Great Dane and Lab who chew large bully sticks instantly. Much more economical. It's not their favorite choice of chew, but it definitely keeps them busy. Has longer staying power than Buffalo Horns and other natural options. Friends recommended based on their small dogs love of these chews that last forever.My dogs love these bones. They last them about a year before we have to order new ones.I have a 1 yo lab and 7 y.o beauceron. Very heavy chewers. HiWhat I like, they are clean, unfilled, large (thick and long) and natural. Not filled with weird stuff I wonder if it'll make a mess, grow old and yucky, or my dog lick her tongue raw. My dog loves to chew these, or toss them around. Which leads to the one thing that concerns me. She loves to playfully toss these bones around, especially in the stone floor. I have figured out she has learned that this can make the bone chip. On a old bone it eventually cracked the length of the bone. But still these bones are long and thick, so they still won't be dangerous. But it is Our responsibility to pick up chips and toss dangerous bits/boness. These are Large natural bones doing natural things, but these still have lasted months so far. I expect they will be around for months yet. Unlike the $40 ach antlers I bought my dogs for Xmas, chewed to dangerous nubbs in under 2 weeks. I will continue to buy these bones.I highly recommend these bones.
