Skin and Coat Problems

Dietary Causes

  • Essential fatty acid deficiency (omega 3/6 balance)
  • Zinc deficiency (genetic malabsorption)
  • B-vitamin deficiency (biotin)
  • Protein source allergy
  • Poor food quality

4 Pillars of a Skin-Supporting Diet

1. Omega-3 (EPA, DHA) 50-100 mg/kg/day, fish oil. Noticeable improvement after 4-8 weeks.

2. Zinc Red meat, liver, fish. Especially for Husky-type breeds (genetic).

3. Biotin and B-Vitamins Egg yolk, liver.

4. High-Quality Protein For allergies: novel protein (duck, venison, kangaroo). For atopy: hydrolyzed.

Atopy

  • Daily Omega-3 supplementation reduces itching
  • Hypoallergenic/novel protein food
  • Washable bedding, frequent bathing

Dandruff, Dry Coat

  • Increase omega-3 intake
  • Egg yolk 2-3 times weekly
  • Avoid dry, low-fat food
  • Thyroid function check

Dull Coat

  • Copper deficiency (black dogs turn gray)
  • Tyrosine deficiency
  • Old age (normal)

Excessive Scratching

  1. Flea check (most common!)
  2. Food elimination diet 8-12 weeks
  3. Atopy test
  4. Thyroid function

8-Week "Skin Improvement Program"

  • Daily fish oil supplementation
  • High-quality food
  • Medicated shampoo once weekly max
  • Egg yolk 2 times weekly

If no improvement after 8 weeks → veterinarian.
