Generally speaking, yes.

Sardines offer plenty of omega 3 fatty acids which are great for your dog’s skin and coat health. Furthermore, these fatty acids may also ease inflammation (which helps with mobility, particularly for older dogs.)

Are Sardines Safe For Dogs?

The best canned option will come with only water. You don’t want to pick the cans with added salt or additives.

Can Dogs Eat Sardines in Olive Oil?


It’s best to stick with water-based sardines only.

While a small amount of olive oil might be beneficial to a dog, too much is likely to cause stomach upsets. It’s also high in fat and calories, which isn’t good for overweight dogs, or those who may be susceptible to pancreatitis.

Can Dogs Eat Sardines in Sunflower Oil?


Sunflower oil is very high in omega-6 fatty acids, and it’s not in proportion with the omega-3s.

As such, it’s not well suited to a dog’s digestion, and it could be bad for their immune system, too.

Can Dogs Eat Sardines in Soybean Oil?


Soybean oil contains a lot of saturated fat, especially compared to other common vegetable oils. As such, it’s best to avoid it and stick to sardines in water.

However, it’s better to use sardines in water, especially if you’ll be giving sardines to your dog on a frequent basis.

Can Dogs Eat Sardines in Mustard Sauce?


Mustard is toxic to dogs, and it will usually make them vomit.

Sardines are soft-boned fish that shouldn’t cause any issue. What’s more, the calcium content may even be beneficial.

But if you want to be on the safe side, it’s useful to chop the sardines into smaller pieces before you serve them.

Also, be careful with larger sardines… as you may need to remove the backbone from these ones.

Can Dogs Eat Sardines Every Day?

It’s generally not a good idea to feed your dog sardines everyday.

Instead, it’s better to give them as an occasional treat, as part of a balanced, healthy, canine-friendly diet.

Some dogs may develop a fishy smell if they’re eating sardines too often.

Also, sardines can be quite calorie-heavy.

How Can I Serve Sardines To My Dog?

You can chop them up into smaller portions to mix with their regular food, or simply use them as a tasty fish-based treat that your dog will enjoy.

Keep in mind: You should only feed your dog either fresh sardines or canned sardines served in water. You’ll want to avoid anything in brine, mustard, or oils.
