Why Feed Sardines to Dogs?

Sardines are often considered one of the best fish to include in a dog’s diet because they provide naturally occurring omega-3 fatty acids, which support healthy skin, a shiny coat, joint health, brain function, and overall health.

When buying canned sardines, choose ones packed in water with no added salt, oil, or seasonings.

FAQ

Are sardines better than fish oil for dogs?

Both have benefits. Fish oil provides concentrated omega-3 fatty acids, while sardines offer omega-3s plus protein, vitamin D, calcium, vitamin B12, selenium, and other whole-food nutrients. Sardines are an excellent way to add a variety of nutrients naturally, while fish oil is best when a higher dose of omega-3s is needed.

Choose sardines that are packed in water with no added salt or seasonings. As a general guideline, look for products with less than 150 mg of sodium per 85 g (3 oz) can whenever possible. While higher-sodium varieties can still be fed occasionally to healthy dogs, lower-sodium options are a better choice for regular use.

These are the sardines we suggest

Can dogs with kidney or heart disease eat sardines?

Dogs with kidney disease, heart disease, or those on a sodium-restricted diet should be more cautious with sardines, as canned sardines naturally contain sodium—even when they're packed in water.

If your dog has one of these conditions, choose the lowest-sodium sardines available (ideally 150 mg of sodium or less per 85 g / 3 oz can) and speak with your veterinarian or nutritionist before feeding them regularly.

Can dogs eat fresh sardines?

Yes! Fresh sardines are an excellent choice for dogs and are naturally rich in omega-3 fatty acids, high-quality protein, vitamin D, vitamin B12, and selenium.

You can feed sardines:

  • Raw, if they've been properly handled and frozen according to food safety guidelines.

  • Cooked by baking, steaming, poaching, or grilling without added salt, oil, or seasonings.

Fresh sardines are generally lower in sodium than canned sardines, making them a great option for dogs that need a lower-sodium diet. If feeding whole fresh sardines, the soft edible bones are an excellent source of calcium.
