Should You Add Fish Oil to Your Dog’s Diet?

Fish oil is one of the most popular supplements for dogs—and for good reason. Packed with omega-3 fatty acids, it supports everything from skin health to joint mobility.

But should you add it to your dog’s daily routine? Let’s dive into the benefits, the risks, and how to use fish oil safely.

What is Fish Oil?

Fish oil is extracted from fatty fish such as salmon, sardines, and mackerel. It contains two powerful omega-3 fatty acids:

  • EPA (Eicosapentaenoic Acid)
  • DHA (Docosahexaenoic Acid)

These acids are not only anti-inflammatory but also essential for cellular function and brain development.

Benefits of Fish Oil for Dogs

🐶 1. Shinier Coat and Healthier Skin

Fish oil can help:

  • Reduce dandruff and itching

Perfect for dogs with seasonal allergies or chronic dry skin.

🦴 2. Joint and Mobility Support

Omega-3s have anti-inflammatory properties that may:

  • Reduce stiffness in senior dogs

  • Support active, athletic dogs

🧠 3. Cognitive and Neurological Benefits

DHA supports brain development, especially in puppies and aging dogs. It may improve:
