Here is what I found:

"This is one of the biggest myths of all time! Raw chicken bones are fantastic for your dog. They are soft enough so that they bend easily, and break well for the dog to digest.

On the other hand, cooked chicken bones can be a problem, and I recommend that you DON'T feed COOKED chicken bones.

Some people are worried about their dog choking on bones. While such incidents are very rare (far more incidents occur with dogs choking on kibble), I encourage the feeding of bigger portions of meaty bones, or if available, whole carcasses, such as whole chickens or rabbits.

So could a raw chicken bone kill a dog? Well I guess that anything is possible. Certainly scientifically you can't prove a negative argument. However what we do know is that dogs have died from inhaling kibble the wrong way and choking and suffocating to death.

Feeding your dog is about management of risk. No matter which path you decide to take there is always risk. There is always someone who will criticise your decision. However you, and only you can decide what is best for your dogs. Weigh up all the benefits and risks. Do your own analysis. Do your research. Do what will have the greatest overall benefit for your dog."I believe this is what was posted earlier.
