Fish oil is super popular for dogs and for good reason: it’s packed with omega-3s, like EPA and DHA, that help with everything from their brains to their joints.

Most dog owners know these healthy fats are great for their pet’s overall well-being, but what they might not realize is that producing fish oil can be rough on the environment. Overfishing to meet the demand for fish, squid, and krill oil is straining ocean life in a big way.

That’s why it’s time to look at more eco-friendly alternatives that still provide all the awesome benefits of fish oil.

Spoiler: there are great DHA options out there that not only keep your dog healthy but also help protect our oceans from overfishing.

Let’s dive into why omega-3s are so important for dogs and the planet-friendly ways you can get them.

The Health Benefits Of EPA And DHA

First of all, why worry about these fats in the first place?

Well, EPA and DHA are basically the powerhouses of omega-3s. They do wonders for your dog’s health, like keeping his brain sharp, joints moving smoothly, and eyes clear.

DHA, in particular, is great for puppies and older dogs because it supports brain function and vision, while EPA helps with keeping inflammation in check—super important for dogs with joint pain or skin issues.

On top of that, omega-3s are great for boosting a dog's immune system, helping your dog stay strong against infections and illness.

If you pair omega-3s with probiotics, you’re giving your dog an even bigger health boost. Probiotics help your dog absorb these fatty acids better, making sure they get the most out of every meal.

Green Lipped Mussels: A Sustainable Alternative

The only problem with DHA is that some of its sources contribute to overfishing or other sustainability problems. This is especially the case with fish oil.

Luckily, green-lipped mussels are a fantastic, earth-friendly substitute for fish oil. They’re loaded with EPA and DHA, plus an extra omega-3 called ETA that’s known for its ability to support a healthy inflammatory response.

Unlike farmed fish, which can be full of omega-6 (the not-so-good fats), green-lipped mussels feed naturally on phytoplankton, making them a super clean and sustainable choice.

If your dog struggles with joint pain, green-lipped mussels might even be better than fish oil. Studies show that dogs given green-lipped mussel supplements see a bigger improvement in their joint mobility and stiffness.

Plus, these mussels come with a little bonus: SOD (Superoxide Dismutase), a powerful antioxidant that fights aging and keeps your dog feeling young and active. So, not only are you supporting your dog’s health, but you’re doing it in a way that’s kind to the planet.

Phytoplankton: The Source Of Marine Omega-3s

Phytoplankton might be tiny, but they’re another sustainable DHA source packed with big benefits for your dog. These microscopic marine plants are loaded with EPA and DHA, making them an awesome, eco-friendly alternative to fish oil.

Since phytoplankton is a primary source of omega-3s for ocean life, you’re going straight to the source when you add them to your dog’s diet. Phytoplankton is also rich in antioxidants, including SOD (Superoxide Dismutase), just like green lipped mussels.

The great thing about phytoplankton is that a little goes a long way. Since it’s so concentrated, you only need to add a tiny amount to your dog’s food to get those valuable nutrients. Usually, 1/8 teaspoon a day is enough for any size dog, making it an easy, low-maintenance way to boost your pet’s omega-3 intake while being kind to the planet.

Brains And Eyes: An Unconventional Yet Nutritious Option

While it may sound a bit unconventional, feeding your dog brain and eye tissues can be a powerhouse for nutrition.

Both organs are loaded with EPA and DHA, the same omega-3s found in fish oil, and they come packed with extra nutrients like phosphatidylserine and vitamin A. These nutrients aren’t just good for physical health; they also do wonders for your dog’s cognitive function, helping support memory and brain health—especially important for older dogs or those showing signs of cognitive decline.

If you want to try adding brains and eyes to your dog’s diet, start slow. These organ meats are incredibly rich, so introducing them gradually can help avoid any tummy trouble. Over time, your dog can enjoy the full benefits, and you’ll know you’re giving him a natural, nutritious boost that supports both body and brain.

Bonus: GLA-Rich Plant Oils For Skin And Coat Health

While omega-3s get a lot of attention, there’s another fatty acid you should know about ... and no, I'm not talking about alpha-linolenic acid (ALA) or even eicosapentaenoic acid (EPA).

I'm talking about gamma-linolenic acid (GLA). GLA is a type of omega-6 that’s actually anti-inflammatory and great for supporting healthy skin, a shiny coat, and balanced hormone levels. If your dog has skin issues or joint pain, adding a GLA-rich oil like hempseed oil to their diet can provide much-needed relief. Hempseed oil not only offers GLA, but also omega-3s and SDA (stearidonic acid), which support heart health and help manage inflammation.

For a plant-based option that’s even richer in GLA, check out ahiflower oil. It has a more balanced omega-6 to omega-3 ratio than hempseed, making it an ideal choice for dogs who need a little extra help with inflammation or skin hydration.

To start, give your dog about 1/4 teaspoon of ahiflower oil for every 20 to 25 pounds of body weight. It’s an easy, natural way to nourish your dog’s skin and keep their coat looking its best while supporting overall wellness.

Choosing Earth-Friendly Alternatives To Fish Oil

The environmental impact of fish oil production is pretty significant. Sourcing fish, squid, and krill oil contributes to the depletion of already stressed marine ecosystems, not to mention the harmful practices of overfishing.

By turning to the earth-friendly alternatives above like green-lipped mussels, phytoplankton, or plant-based oils, you’re doing your part to reduce the strain on the planet. Plus, you’re helping preserve the ocean’s delicate balance—after all, our pets aren’t the only ones that rely on marine life for survival. Whales, dolphins, and seabirds are all affected by the massive removal of these crucial species.

Switching to sustainable options doesn’t mean sacrificing your dog’s health benefits either. In fact, alternatives like green-lipped mussels often pack even more benefits than traditional fish oil. With the same powerful omega-3s (EPA and DHA) and added nutrients like SOD or GLA, you’re not only supporting your pet’s well-being but doing so in a way that’s kinder to the environment. It’s a win-win for your dog and the planet!

Practical Tips For Adding Omega-3s To Your Dog’s Diet

When it comes to adding omega-3s to your dog’s diet, it’s important to get the dosage right.

• For green-lipped mussels, aim for around 1,500 mg for a 50-pound dog, while phytoplankton typically only requires 1/8 teaspoon per day for any size.
• If you’re using plant-based oils like hempseed or ahiflower oil, start with about 1/4 teaspoon per 20-25 pounds of body weight.

Start slow to avoid any digestive upset—new additions to a diet can be a bit of a shock to your dog’s system. Gradually increase the amount over a week or so, giving their body time to adjust.

To make sure these omega-3s are absorbed properly, pair them with healthy fats like coconut oil or kefir. This not only boosts absorption but also gives an extra nutritional punch, making sure your dog gets the most out of these health-boosting additions.

And remember ... it’s always best to consult with your holistic vet, especially if your dog is on other medications or has health conditions.
