I don’t see where anybody said it was healthy.
For larger dogs (40 lb or more) the idea that they can’t eat chicken bones is largely a myth. The danger of splintering/perforation is mostly with small dogs.
Yep, that’s why one of my dogs had a $1000 tooth extraction. Cracked tooth from eating beef bones. So no more bones for either dog.
That’s not true for the chicken parts I buy. They always contain part of the pelvis when I buy them. Might be a regional preference here in the central U.S.
