Why Oysters Needs Care
Cooked oysters are a zinc-rich treat most dogs can have in tiny amounts, but raw oysters risk bacteria and shell fragments are a hazard.
The main thing to watch: raw shellfish carries bacteria; allergy possible.
How to Serve Oysters Safely
Cooked plain with shell fully removed; a small amount chopped over food. Never raw.
