Without mods, bones serve as food for dogs and I think you can make fishing hooks from them.

Let me add that bone is 'low density' dog food (compared to meat in any form) while it is logically expected, I would like to mention that it does make a difference in the game.
If you are not in rush to go elsewhere after feeding dogs that is of course no problem at all, they will slowly chew the bone and eventually will feel full...
On the other hand if you are in rush to feed dogs & then go elsewhere with your dogs, then this will be a delayer as it takes dogs a long time to consume adequate bone to feel full.
