Dogs can eat pork, but it must be cooked, plain, and lean. Raw or undercooked pork is unsafe because it may contain parasites like trichinella, which can cause trichinosis. Pork with added seasonings, sauces, or high fat content should be avoided as these can be harmful to dogs. Pork bones, especially cooked ones, should never be given to dogs because they can splinter and cause serious injuries. Lean cuts of cooked pork, used occasionally as a treat, can be a good source of protein and essential nutrients for dogs.
