A shiny coat starts in the food bowl, then the brush, then a bath schedule that doesn't overdo it. Heavy or patchy shedding needs a vet; a different shampoo won't fix it.
Still not working?Common mistakes. Over-bathing: it strips natural oils.
The short answer
A healthy dog coat starts with proper nutrition (especially omega fatty acids), regular grooming, and appropriate bathing. Ask your vet before adding a supplement like fish oil. Dull, dry, or excessive shedding often indicates nutritional deficiency, allergies, or underlying health issues.

What Makes a Healthy Coat
Key takeaways
A healthy coat starts with a complete diet; ask your vet about omega-3s
Dull, dry coats often signal underlying health issues worth a vet check
Over-bathing strips natural oils, so bathe when your dog needs it, not on a timer
Regular brushing is the habit that keeps coats tidy between grooming visits
A healthy dog coat should be:
Shiny but not greasy
Soft and smooth to touch
Full without bald patches
Additional tips: free of excessive dandruff, resilient and not brittle.
Your dog's coat is a reflection of their overall health. When something's off internally, it often shows externally. Start with the food side in our skin and coat picks for dogs, then the bath side in our sensitive skin grooming picks.
Nutrition: The Foundation
Essential Nutrients for Coat Health
Protein: Hair is made mostly of protein, so quality protein sources matter
Omega-3 fatty acids: a common pick for dull coats (ask your vet about dosage)
Omega-6 fatty acids: found in many dog foods; check the label
Zinc: A standard mineral in complete dog foods
Biotin: Promotes hair growth and strength
Vitamin E: Antioxidant protection for skin cells
Signs of Nutritional Deficiency
Dull, dry coat
Excessive shedding
Brittle hair that breaks easily
Additional tips: dry, flaky skin, slow hair regrowth after shaving.
Supplements for Coat Health
Fish Oil
Rich in omega-3s (EPA and DHA)
Additional tips: look for high-quality, mercury-tested products, dosage based on your dog's weight.
Other Helpful Supplements
Coconut oil: Can be given orally or applied topically
Biotin: Supports hair growth
Zinc: Part of a complete diet; ask your vet before adding more

Common mistakes

Skip these
Over-bathing: it strips natural oils. Bathe when your dog is dirty or smelly, not on a timer.
Shaving a double coat: never. The undercoat regulates temperature.
Skimping on the rinse: shampoo residue causes dullness and irritation.
Starting supplements without your vet: always consult your vet first, and ask about omega-3 dosage.
Ignoring problems that hang on: sudden shedding, bald patches or scratching with hair loss mean a vet visit.
The Bottom Line
In short
A beautiful coat is built from the inside out. Start with quality nutrition and consider omega fatty acid supplements. Add regular grooming for your dog's coat type, and don't over-bathe. Coat problems hanging on despite good care? See your vet to rule out a health issue.
