Supporting Your Pet’s Skin from the Inside Out – Why Nutrition Matters as Much as Shampoo

When pets develop itchy, dry or sensitive skin, many owners focus on When pets develop dry, flaky or sensitive skin (I would remove the highlighted section making it more direct), many owners understandably focus on shampoos and topical treatments. While gentle cleansing plays an important role, true skin health relies on more than what is applied to the surface.

Healthy skin is built from within. Nutrition provides the structural components the body needs to maintain a strong, resilient skin barrier. Without appropriate internal support, even the most carefully selected grooming products may not achieve optimal results.

Understanding the relationship between nutrition and skin health can help pet owners take a more balanced, long-term approach.

The Skin Barrier: More Than Just a Surface Layer

Your pet’s skin is not simply a covering - it is a complex organ with multiple functions. It helps:

• Protect against environmental irritants
• Regulate moisture levels
• Support temperature control
• Contribute to immune function
• Maintain coat quality

The outermost layer, often referred to as the skin barrier, plays a crucial protective role. When functioning normally, it helps prevent excessive moisture loss while limiting penetration of external irritants.

If the barrier becomes weakened, pets may become more susceptible to dryness, sensitivity or recurring irritation.

Why Skin Health Depends on Nutrition

The skin continuously renews itself. New skin cells are produced and gradually replace older cells. This constant renewal process requires specific nutrients, including:

• Essential fatty acids
• Proteins
• Vitamins
• Minerals

If nutritional intake does not fully support this renewal process, the skin may appear:

• Dry or flaky
• Less elastic
• Dull in appearance
• More reactive to environmental threats

Nutrition therefore plays a foundational role in maintaining normal skin structure and function.

The Role of Essential Fatty Acids

Among the most important nutrients for skin health are omega-3 and omega-6 fatty acids.

These essential fatty acids:

• Contribute to normal skin hydration
• Help maintain elasticity and flexibility
• Support the integrity of the skin barrier
• Contribute to a balanced inflammatory response

Because pets cannot produce these fatty acids themselves, they must obtain them through diet.

Even pets fed complete commercial diets may benefit from targeted supplementation in certain situations, particularly those with sensitive or environmentally challenged skin.

Why Shampoo Alone Isn’t Enough

Topical cleansing helps remove:

• Surface debris
• Environmental allergens
• Excess oil
• Loose hair

However, shampoo acts only on the outer layer of the skin and coat. It does not provide the building blocks needed for skin cell renewal or barrier maintenance.

This is why an inside-out approach — combining nutrition and appropriate grooming — provides an integral care that is more supportive than relying on either strategy alone.

Nutritional Support with COATEX®

The COATEX® range from VetPlus has been formulated to provide targeted essential fatty acid support for skin and coat health. 

COATEX® Capsules

• Provide a balanced combination of omega-3 and omega-6 fatty acids
• Designed for daily use
• Suitable for long-term nutritional support
• Help maintain normal skin hydration and coat condition

COATEX® Essential Fatty Acid Liquid

• Offers flexible dosing
• Easily mixed with food
• Particularly useful for cats, small dogs or pets reluctant to take capsules

These products are nutritional supplements, not medicines. They are designed to support normal skin and coat function when used consistently as part of a balanced diet.

Combining Internal and External Care

For many pets, the most supportive routine includes:

• Daily essential fatty acid supplementation
• Regular brushing to remove debris
• Gentle bathing with pet-specific shampoos
• Environmental management where possible

Within the COATEX® topical range:

• COATEX® S Shampoo supports gentle cleansing for sensitive skin
• COATEX® M Shampoo may be used when deeper cleansing is advised by a veterinary professional

This combined approach helps maintain skin comfort and coat quality over time.

Realistic Expectations

Skin renewal takes time. Because supplements support the natural skin cycle, visible improvements may develop gradually over several weeks.

Consistency is key. Daily nutritional support helps maintain ongoing skin barrier integrity rather than attempting to address issues only once they arise.

When to Speak to Your Vet

While nutritional support can contribute to maintaining healthy skin, persistent or severe symptoms should always be assessed by a veterinary professional.

Seek veterinary advice if your pet shows:

• Ongoing itching
• Redness or swelling
• Hair loss
• Skin lesions
• Sudden coat changes

Your vet can determine whether nutritional support, topical care adjustments or further investigation is required.

If you’re concerned about your pet’s skin health, speak to your vet about whether an inside-out approach using COATEX® products could form part of their tailored skin care plan.
