These have lasted my dogs way longer than I thought. My dogs chew on them probably a few times a week, they rotate which ones they use. The only reason I am not giving 5 stars is because they are small. I think Large Chew toy, I think a Large Chew Toy. These are better fitted for Medium to Small Sized Dogs.

Durable for the aggressive chewer.

Color: 3 PCS

My dogs love this product. One of them is a really aggressive chewer. She will chew on this for over an hour at a time. They are very durable and I don't have to worry about them breaking off large chunks and swallowing them.
