I know the danger: the bone will splinter and the shards will puncture the intestine and your dog will die a slow and horrible death.
I am skeptical of this claim, not because the danger doesn’t exist — I’m sure it does — but for these reasons:
1) dogs are nuts about bones, I think for the fun of gnawing and the reward of calcium in the bone itself and for the protein-rich marrow; I think they know what they are doing after 250,000 years of experience and that they have acid in their stomachs to help digestion and guard against this danger;
2) my own dog periodically shatters a bone as fast as possible and swallows the particles because he knows I will take it away from him just when he’s getting to the good part; he always digests with no distress; and
3) when I took my daughter’s dog to the vet in a panic because he had cracked, shattered and swallowed a Vietnamese-cooked chicken bone to keep me from taking it, the vet said, “Not only is he okay, but I have never in 25 years had a dog die from eating a bone.”
What is your theory and your practice? Yes, I have tried buying the big bones that he can’t break and swallow, but he isn’t interested.
