Does your four-legged friend love fish? Should they reap the rewards, or should they avoid this type of fish altogether? In this blog post, we’ll answer the question “Can dogs eat sardines?” and provide tips on how to feed them this healthy snack.
Is It Good to Feed Sardines to Dogs?
Can dogs eat sardines? Sure thing! Sardines are small, oily fish that are often canned and used as a source of protein. They’re an excellent source of omega-3 fatty acids, which have been shown to improve cardiovascular health, joint function, and cognitive function in humans.

In addition, sardines contain high levels of B vitamins, iron, and calcium. Vitamin B12 improves energy levels and mental function. As your dog gets older, the nutrients in sardines can be especially beneficial. Sardines can help to reduce inflammation throughout the body, including the skin and joints. This can lead to a shinier, healthier coat and less itching, scratching, swelling, and pain. Thanks to the fish oil!
Are Sardines Always Safe for Dogs?
While sardines offer a wealth of health benefits for dogs, there are some potential side effects to be aware of as well. So, can dogs eat sardines? These fish are very fatty, which can harm dogs if consumed in large quantities. Too much fat in a dog’s diet has been linked to weight gain and an increased risk of pancreatitis.
Therefore, it’s important to only feed your dog a small amount of sardines at first to see how they react. If everything seems okay after a few days, you can gradually increase the serving size over time.
You may have heard that some fish are high in mercury. Mercury is a heavy metal that is harmful to dogs (and humans) if consumed in large quantities. Fortunately, sardines are the fish species that contains the lowest level of mercury.
Can Dogs Eat Sardine Bones?
There is some debate over whether dogs can eat sardine bones. Some people say that they’re fine for dogs because they’re soft, but others argue that the bones can splinter and cause internal damage. There is no definitive answer to “Can dogs eat sardines with bones?”, as each dog will have a different reaction to eating them.
It also depends on whether you’re buying the sardines raw or canned. When they’re cooked before being put in a can, the bones soften so much that they’re unnoticeable. But if you’re buying them raw, the bones are still hard and fibrous.
If you’re at all unsure about whether your dog can eat sardine bones, it is best to err on the side of caution and avoid giving them to him. It’s a good rule of thumb not to give dogs any type of bone, as they can often choke on them. Stick with chew toys instead!
Can Dogs Eat Canned Sardines?
Canned sardines are typically a good option, as they’re pre-cooked and have soft bones. However, it’s important to check the label to make sure that the sardines haven’t been smoked or heavily processed, as these treatments can add unhealthy levels of sodium and chemicals to the fish. If you’re feeding your dog canned sardines for the first time, start with a small portion and watch for any signs of gastrointestinal upset.

What Types of Sardines Are Good for Dogs?
The best type of sardine for your dog depends on their size and preference. Smaller dogs may do better with canned sardines because they’re easier to chew, while larger dogs may prefer fresh sardines. Sardines packed in water, olive oil or sunflower oil are all safe for dogs.
Avoid the sardines in tomato sauce, as these contain sugar, salt, additives and seasonings like garlic and onions. Otherwise, you can freely give your dog these small fish, adding them to the daily dog food bowl. However, don’t feed them too many because they do contain high levels of cholesterol (about 60% higher than beef). But if you’re not giving them more than 1–2 sardines 2–3 times a week, it should be fine.
Can Dogs Eat Sardines? Final Reassurance
Time to sum up! Can dogs eat sardines? Yes! Sardines are a great source of protein and fatty acids, which makes them an excellent choice for dogs. They can be fed whole or canned, and their soft bones are rather safe to eat. Make sure to give your dog plenty of water when feeding them the small fish, as they can be high in salt.

Frequently Asked Questions
How Much Sardines Can I Give My Dog?
If you have a small dog, one sardine per week is a good amount. Medium-sized dogs can have a sardine 2–3 times a week. For large pups, you can increase the portion size to 2–3 sardines a few times per week (instead of a regular meal).
What Happens If a Dog Eats Sardines?
If your dog eats sardines in moderation, they’ll be healthier and happier! But if they somehow eat the entire can in one sitting, there could be some side effects such as weight gain, digestive upset and constipation.
Is It OK to Give Dogs Sardines Every Day?
No, it’s not a good idea to feed your dog sardines every day. Too much fat can be harmful, so it’s important to only give your dog sardines occasionally.
Can I Mix Sardines With Dog Food?
As long as your dog is fine with it, yes, you can mix sardines into their regular dog food. Just make sure to introduce them slowly and monitor your pup’s reaction. If they experience any side effects, stop giving them sardines right away!
Can Sardines Give Dogs Diarrhea?
Yes, sardines can contain high levels of salt and fat, which can lead to diarrhea if given in excess. However, this side effect is more likely to occur if your dog eats canned sardines, as these tend to be more processed and contain added ingredients.
Is Salmon Better Than Sardines for Dogs?
Yes and no. Salmon is a leaner fish, meaning that it’s a better source of protein. However, salmon does not contain the same amount of omega-3 fatty acids as sardines. As a result, it’s really up to you and your dog to decide which fish is best for them.
