To give a quick and fast answer Yes dogs can eat oysters as long as they are not fried and in moderation. However it isn’t recommended that you feed this food to your dog as they could be allergic and there isn’t much nutritional benefit for dogs.
Oysters are often eaten raw by people but this can be very dangerous for a dog to do. As well oysters really don’t have nutritional benefits for a dog.
In addition you cannot feed anything that is fried to your dog as it is bad for their health.
Some dogs are also allergic to seafood and could have some adverse effects after eating seafood. Therefore it would be best to avoid the situation all together and not have dogs eat seafood.
However if your dog was to sneak some seafood it is important to watch them closely to see if you notice any negative health issues they may experience.
If you are worried it would be best to take your dog to the vet right away to get checked out.
Again to answer the question can dogs eat oysters the answer is technically yes but it isn’t recommended and they cannot be fried.
