Benefits of Green Lipped Mussel for Dogs 

Green lipped mussel (Perna canaliculus) is a shellfish native to New Zealand, and is commonly used in pet supplements because it contains omega-3 fatty acids and other naturally occurring compounds that may help support joint health. The main reported benefits of green lipped mussel include:

  • Joint mobility and comfort: Some studies suggest that the omega-3 fatty acids found in green lipped mussel can be effective at reducing the inflammatory processes associated with joint discomfort and stiffness in dogs with osteoarthritis, therefore helping with mobility. 
  • Supporting an active lifestyle: Maintaining comfortable movement in the joints can help dogs continue enjoying their usual walks and everyday activities.

  • Providing nutritional support: Green lipped mussel contain a range of bioactive lipids, including fatty acids, anti-oxidants and minerals, although its exact composition varies between extracts and products.

VioVet vet, Dr Sarah Dantas-Goddard CertAVP MRCVS, adds: “While there is evidence to suggest that green lipped mussel can provide positive effects such as improved comfort and mobility in dogs with osteoarthritis, the degree of improvement can vary depending on different dosages and different extracts used. It is best considered as part of a wider joint-care plan that includes appropriate exercise, weight management and veterinary advice". 

Does Green Lipped Mussel Help Arthritis in Dogs?

Green lipped mussel may help some dogs with arthritis, a condition that causes joint inflammation, discomfort and reduced mobility. Its omega-3 fatty acids, including EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are thought to contribute to its potential anti-inflammatory effects. 

Some studies carried out in dogs with osteoarthritis have reported improvements in clinical signs following supplementation, although careful interpretation of these studies and further research is needed. 

It may be worth discussing with your vet if your dog:

  • Seems stiff after resting.
  • Is reluctant to jump or climb stairs.

  • Has been diagnosed with arthritis.

  • Needs additional joint support.

Important: If your dog is limping, struggling to stand or showing signs of pain, consult your vet. Supplements should complement, not replace, appropriate veterinary treatment.

Is Green Lipped Mussel Safe for Dogs?

Green lipped mussel supplements formulated specifically for dogs are generally well tolerated when used according to their instructions. However, they are not suitable for every pet.

Possible concerns include:

  • Digestive upset: Some dogs may experience soft stools, vomiting or diarrhoea.
  • Allergic reactions: Dogs with shellfish allergies or sensitivities may react to the ingredient.

  • Product quality: Contamination, poor storage or inconsistent ingredient concentrations can affect supplement quality.

  • Interactions and underlying conditions: Your vet should review supplementation if your dog takes medication or has a medical condition.

Choose a reputable product with clear ingredient information and feeding instructions. If your dog develops symptoms after starting a supplement, stop giving it and contact your vet. 

Green Lipped Mussel vs Fish Oil

Both green lipped mussel and fish oil can provide omega-3 fatty acids, but they are not identical.

Feature

Green Lipped Mussel

Fish Oil

Main nutrients

EPA and DHA, as well as other omega-3s, anti-oxidants and minerals 

Primarily rich in EPA and DHA omega-3s

Potential benefits

Targeted joint health and mobility support

Broader anti-inflammatory benefits, supporting coat and skin health, as well as joint health. 

Formulations

Powders, oils, extracts and capsules

Oils, capsules and some powders

Best choice

Depends on the product and your dog's needs

Depends on EPA/DHA content and your dog's needs

Green lipped mussel may appeal to owners looking for a more joint-focused supplement, while fish oil provides a more direct way to supplement EPA and DHA with broader benefits.

Neither is automatically better. Compare the active ingredients, concentration, quality and recommended serving rather than choosing based on the ingredient name alone. Your vet can help determine which option is most appropriate for your dog.

Green Lipped Mussel vs Glucosamine

Green lipped mussel and glucosamine are both common ingredients in canine joint supplements, but they work differently.

  • Green lipped mussel: Provides omega-3 fatty acids and other compounds that may help support joint comfort and mobility.
  • Glucosamine: Is involved in the formation, repair and maintenance of cartilage, which in turn supports the joint. 

Evidence for both ingredients varies, and neither should be considered a cure for arthritis. Some products combine green lipped mussel with glucosamine, chondroitin or other ingredients.

The best choice depends on your dog's individual needs and the formulation being considered. Combining supplements is not always necessary, so check with your vet before adding multiple products to your dog's diet.

FAQs

Dr Sarah Dantas-Goddard CertAVP MRCVS answers your common questions about green lipped mussel.

How much green lipped mussel should  I give my dog per day?

The daily dose of green lipped mussel depends largely on your dog's weight, the brand of the product and therefore the concentration within that specific product, and the format that you are using (such as powder, capsules, or oil). Always read and follow the instructions provided on the packaging.

Can dogs be allergic to green lipped mussel?

Yes, dogs can experience allergic reactions. Green lipped mussel is a type of shellfish, therefore dogs with a known or underlying shellfish allergy or intolerance can experience adverse effects when taking this as a supplement.

Can green lipped mussel cause diarrhoea in dogs?

Yes, loose stools and diarrhoea are the most frequently reported side effects, especially if the supplement is introduced too quickly or if the dog has an underlying food intolerance of allergy to shellfish.

How long does green lipped mussel take to work in dogs?

Most therapeutic benefits are typically seen after 6-8 weeks. However, this can vary depending on the severity of the osteoarthritis, the concentration and the form of the product, as well as the loading dose given.

Can puppies take green lipped mussel?

Yes, as there is no minimum age restriction. However, while it may be safe to give to young dogs, this should be discussed with your vet first to ensure your puppy's primary focus remains on a balanced and complete diet, with good growth and weight control.

Can I give my dog green lipped mussel and fish oil together?

Yes, you can give these together, but precaution is needed as many joint supplements actually combine both ingredients already. Doubling up on supplements can result in extremely high doses of omega-3s, which over a long period can have adverse effects. 

However, given in the correct amounts, they complement each other well and offer dual-action support: fish oil handles broader systemic anti-inflammatory needs, while green lipped mussel targets joint support and mobility more specifically.
