What happens if you feed a dog raw chicken heads?

Chicken heads are not recommended: they are bony with little meat, give little nutrition, and are hard to digest. While chewing, bone shards may lodge in the throat or narrow gut, causing breathing difficulty, gagging, and appetite loss.

If a dog often eats chicken heads and knows how to spit bones, moderate feeding is acceptable. Otherwise, prefer chicken breast.

Chicken breast is high in protein and low in fat, better for nutrition without obesity risk.
