okay I have 3 dogs all over 50 lbs. I love nylabones. I don't like this product. It is soft and flexible and has tons of little nubbies. The dogs will chew this apart it is a given but it should last a little while if they aren't an aggressive chewer. Mine are aggressive chewers and shredded this bone. Then the younger one proceeded to eat the pieces. This is not a hard nylabone so I don't recommend to many people.
