The "Miracle" Supplement (Based on Science)

Among all dog supplements, **fish oil** is probably the one with the **most documented benefits**:

  • Shiny and healthy coat.
  • Less stiff joints.
  • Reduced inflammation.
  • Cardiac support.
  • Brain support (puppies + seniors).

Key substance: **omega-3** (EPA + DHA).

But it is necessary to **dose it correctly**. Let's see.

What are Omega-3s

**Omega-3**: essential fatty acids (not synthesized by the body, must be ingested).

**Two main types**:

  • EPA (eicosapentaenoic acid):
    • **Anti-inflammatory** effect.
    • Cardiac and joint support.
  • DHA (docosahexaenoic acid):
    • Brain development.
    • Cognitive function.
    • Vision.

**Together** = complete package.

The Sources

Fish Oil

**Types**:

  • Salmon:
    • Rich in EPA + DHA.
