The World's Strongest Dog Bone by Nylabone is made of heavy-duty virgin DuPont nylon.

These bones are 10 times tougher than any other nylon or polyurethane bone.

Recommended especially for aggressive hard chewing dogs.

It is so strong that you don't have to throw it away when the knuckles are chewed down.

Discard it only when it is small enough for your dog to swallow whole.

Galileo is safe to chew. The thin shavings that are raked off during chewing and swallowed pass through harmlessly.

Galileo saves teeth by effective cleaning and vigorous gum massage

Galileo is non-abrasive so there is no tooth wear.

Natural color. Each bone comes with a booklet.
