Can Dogs Eat Oysters in General?
Yes, dogs can eat oysters. They’re not inherently toxic, like other seafood and fish. But before you give your dog an oyster, there are a few things you need to think about.
- Oysters with shells can be a choking hazard for dogs.
- They can cause gastrointestinal upset, including vomiting and diarrhea, if eaten in large quantities.
- Raw oysters can contain harmful bacteria such as Vibrio, causing vibriosis.
Also, oysters can accumulate domoic acid, which causes amnesic shellfish poisoning if ingested in large amounts. However, they usually contain less of this toxin than mussels do. So can dogs eat oysters? Generally yes, as long as they’re properly cooked and bought from a reputable source.
Health Benefits of Oysters for Dogs
Oysters are a good source of easily digestible protein. They also contain omega-3 fatty acids, which are beneficial for your dog’s health. Oysters can help:
- improve joint health;
- promote a healthy skin and coat; and
- support cognitive function.

If your dog enjoys oysters, it’s OK to let them eat this seafood in moderation, but serve them with caution. Monitor your dog for any signs of toxicity after they’ve eaten oysters. And don’t give them too many – if you’re having 6 oysters yourself, aim for 1–3 for your dog.
Can Dogs Eat Oysters From a Can?
There are many types of oysters on the market, including smoked oysters, pickled oysters, canned oysters, and many more. You can give your dog any of these types of oysters, but remember to do so with caution. If you’re unsure about how your dog will react to oysters, start by giving them a small amount. If your dog is in poor health condition, you should always ask the vet for advice before feeding them anything new.
Can dogs eat oysters that are canned? Yes, but only one or two as an occasional snack. They can be high in sodium, but they’re still healthier for dogs to eat than fried oysters.
When Shouldn’t Dogs Eat Oysters?
If your dog has any health issues such as liver disease, kidney disease, or pancreatitis, consult with your veterinarian before giving them oysters. They may not be able to eat oysters safely. If your dog has a sensitive digestive system or is allergic to seafood, do not give them oysters.

If They Contain Harmful Additives
Can dogs eat oysters? Yes, but if you want your dog to try them, make sure that there are no other ingredients that may harm their health. These include:
- lemon juice;
- spicy dressings;
- onions;
- garlic.
If They’ve Already Had Some Recently
Also, remember that moderation is key. Don’t give your dog too many oysters at once. You can feed your dog an oyster from time to time as a snack, but don’t overdo it. If you have any doubts regarding oysters, you should contact the vet and ask for instructions.
If You Suspect a Seafood Allergy
Not every dog is the same and some of them can have different response to seafood. Even though seafood is generally healthy, you should monitor your dog’s reaction to this type of food. If there are any issues such as vomiting, diarrhea or strange behavior, take your dog to the vet immediately.
If They Don’t Like Oysters
Oysters may not be food that your dog will love. Some dogs don’t like oysters at all, and in this case, adding them to their dog food could make it unpalatable. Stick to regular dog treats!
Frequently Asked Questions
Can Raw Oysters Hurt Dogs?
Yes, raw oysters can hurt dogs. The shell of the oyster can cause cuts in the dog’s mouth, and the oyster itself can contain poisonous bacteria if it isn’t cooked properly. That being said, if the oyster is deemed safe for human consumption, it shouldn’t harm a dog either.
Are Dogs Allergic to Oysters?
Experts believe that the proteins in oysters are actually beneficial for dogs, and that any adverse reactions are more likely due to an intolerance or allergy to other ingredients in the dish rather than the oysters themselves. However, some dogs may have a seafood allergy, which includes oyster allergy.
What Seafood Can Dogs Eat?
There are a variety of seafood items that are safe for dogs to consume. These include shrimp, salmon, and cod. While these are all safe options, it is important to note that some seafood may contain high levels of mercury and thus should be consumed in moderation.
