Buying Guide
- Source and purity: Look for wild-caught, ocean-sourced fish oils and molecularly distilled products to reduce toxins and heavy metals. Purity certifications and third-party testing add confidence.
- EPA & DHA balance: Higher EPA and DHA values generally support skin, coat, joints, and immune health. Check label specifics to match your dog’s needs (skin vs. joints vs. heart).
- Form and feeding ease: Soft gels are convenient for many dogs, but chews may improve adherence for picky eaters. Consider your dog’s preferences and routine.
- Allergen considerations: Some dogs have fish allergies or sensitivity. Start with a small amount and watch for digestive upset or skin reactions.
- Breed and life stage: Puppies, young dogs, or senior dogs may require different dosing guidelines. Always follow the product’s feeding directions or consult a veterinarian.
- Flavor and palatability: Tasty options (bacon, beef) can improve daily compliance but ensure flavor additives don’t introduce unwanted ingredients for other health considerations.
- Storage and shelf life: Store in a cool, dry place. Some oils are sensitive to heat and light; proper storage preserves potency.
