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.
