Maybe I need to be more specific. I do not give my dogs any of the flavored, consumable chews just because they do get gnawed down too small too quickly. I stick to the solid, hard plastic. A 12 week old should not be gnawing them down very quickly unless you are giving him the very smallest ones. They also make softer, more flexible ones. Some dogs destroy them quickly too. I like them for when I take a puppy out in public because they are quieter. Xanthe was 12 weeks old today. So far, we haven't had to take any dog toys away from her.
Every fall when we get our new puppy, we dig out the smaller Nylabones and some soft rubber toys not suitable for older dogs. Our 14 year old Aster plays little attention to anything except balls, so we can have things out for the puppy. As the puppy grows, one toy after another slowly goes in the storage ottoman including nubbins OK for a small dog. They really seem to prefer broken in chews. When visitors come, we have to collect all the small stuff, and then get it out again later.
The bigger the bone, the longer it will last. Nylabone also makes a tougher grade called Galileo. RubyPitbull is the only one that has ever reported that a dog destroyed the Souper size. You may have to go online to find them and other good stuff such as dinosaurs, rings, Y bones, etc. We even have a set of keys teething toy. We have bought a lot of stuff from
Dog & Pet Supplies - Vet Vax, Inc Pet Supply Store for dogs, cats, horses. I promise I have no financial interest in them.
