Those are things that every newbie thinks about. We all worried some in the beginning. My dogs have been eating raw for over 7 years without one incident. I know literally 100's of people who feed raw and am on several discussion boards with thousands of members. I have heard of 2 incidents of dogs having problems with bones. There have probably been more incidents than that of dogs choking on kibble. Dogs also choke on balls, sticks, squeek toys, processed pig ears, rawhides and literally hundreds of other things. Almost never on bones in a meal.
You will hear all kinds of horror stories like "i have a friend, who's coworker's brother's neighbor's best friend's uncle's next door neighbor had a dog choke on a bone one time." You will probably never hear someone say, "MY dog choked on a bone and had so and so happen."
I did know a lady on a message board one time say her dog swallowed a chicken drumstick whole. The lady panicked and rushed the dog to the emergency vet's office. The vet x-rayed the dog and saw a chicken drumstick in the dog's stomach. He charged her $2,000 for surgery to remove it. I told her later that of course there was a drumstick in the dogs stomach. Where else did she expect it to go after he swallowed it. If they had left it alone for a few hours it would have digested and never heard from again.
I have seen several people on boards say their dog swallowed a big bone and what should they do. The advice is don't do anything, it will take care of itself. I have never heard of physical problems associated with things like this. The people never see any evidence the bone was swallowed.
Dogs have been eating meat, bones, and organs for millions of years. Their bodies have evolved to handle them very efficiently. They know instinctively how to do it. Find something more important to worry about like him getting run over by a car, or attacked by a larger dog, or getting hit by lightening or having a tree fall on him.
Worrying about a dog choking on bones is like worrying about a cow choking on grass. :smile:
