Fish oil, derived from oily fish like salmon, mackerel, sardines, and anchovies, is rich in omega 3 fatty acids (EPA and DHA) and is commonly used as a supplement for dogs. Veterinarians often recommend it to support conditions such as itchy or dry skin, arthritis, allergies, and even cognitive health.
Its benefits can include reducing inflammation, improving skin and coat quality, supporting brain and eye development in puppies, enhancing joint function, strengthening the immune system, and promoting heart health. While results can take weeks to months to appear depending on the condition, consistency is key for dogs to experience the full effects.
Although fish oil is generally safe, giving too much can cause problems. Side effects may include gastrointestinal upset, fishy odor, oily skin, delayed wound healing, or - in serious cases - issues like pancreatitis or increased bleeding risks.
Puppies, in particular, require careful dosing since their bodies are smaller and many puppy foods already contain omega 3s.
For this reason, fish oil should only be used as a supplement to a balanced diet, never a substitute. It is always best to consult a veterinarian to determine the right dosage and ensure it’s appropriate for your dog’s needs.
In cases where a dog consumes too much fish oil, pet parents should contact a veterinarian or pet poison control, especially if their dog has an underlying health condition.
While acute toxicity is rare, chronic overdosing can be harmful over time. Human fish oil products should generally be avoided, as they may contain additives unsafe for dogs. Pet specific formulas with the NASC seal are safest, and with proper guidance, fish oil can be a valuable addition to a dog’s long-term health routine.
Chewy editorial team believes that every dog deserves the best care possible, and sometimes that means adding thoughtful supplements like fish oil to support their overall health.
With the right guidance from a veterinarian, this simple addition can make a meaningful difference in a pup’s comfort, vitality, and happiness.
Above all, the goal is to help pet parents feel confident in giving their dogs the healthiest, most joyful life they can.
