SHAVING DOUBLE COATED BREEDS REPORT 

The Health, Welfare, and Grooming Strategies for Fur-Bearing Breeds: Addressing Shaving Risks, Post-Clipping Alopecia, and Black Skin Disease

1. Introduction

Shaving fur-bearing dog breeds, particularly those with double coats such as Pomeranians, Siberian Huskies, Golden Retrievers, and Samoyeds, is a controversial practice. While some pet owners believe shaving helps keep their dogs cool, it can have serious, long-term health implications. This report explores the risks associated with shaving and excessive scissoring of these breeds, focusing on post-clipping alopecia (PCA) and black skin disease (BSD). It will also provide best grooming practices for supporting hair regrowth in dogs affected by these conditions.

2. Understanding the Double Coat

2.1 What Is a Double Coat?

Double-coated breeds have two layers of fur:

• Guard Hairs (Topcoat): A coarse, longer layer that repels dirt, moisture, and UV radiation.
• Undercoat: A soft, insulating layer that regulates body temperature by trapping air.

These two layers work together to protect the dog from both heat and cold. When shaved or excessively trimmed, the natural insulating and protective functions of the coat are compromised.

2.2 The Myth of Shaving for Cooling

Contrary to popular belief, shaving a double-coated dog does not make them cooler. Instead, it:

• Disrupts their natural temperature regulation.
• Exposes their skin to sunburn and potential heatstroke.
• Reduces their ability to insulate against both heat and cold.

3. Thermal Imaging and the Surface Temperature Misconception

3.1 Why Shaved Dogs Appear Cooler on Thermal Cameras

Thermal (infrared) imaging measures the surface temperature of the dog — not internal body temperature or overall comfort. When a dog is shaved, the skin is more exposed to the environment, allowing heat to escape more freely. This leads to a lower external temperature reading.

However, this does not mean the dog is better at thermoregulating or more comfortable internally. In fact, they may be less equipped to manage their core body temperature without the natural insulation of their double coat.

3.2 How the Double Coat Actually Helps Regulate Temperature

The undercoat traps a layer of air, creating insulation that works both ways:

• In hot weather: It protects against heat by reducing solar gain and reflecting UV rays through the topcoat.
• In cold weather: It retains body heat and reduces loss to the environment.

Removing the coat eliminates this buffer, causing the body to work harder to maintain equilibrium. In extreme temperatures, this can overwhelm the dog’s internal cooling mechanisms, especially since dogs don’t sweat like humans — they rely primarily on panting.

3.3 The Real Meaning Behind a Thermal Image

Important Note:
Thermal cameras show surface heat, not internal thermoregulation. A shaved dog may feel cooler to the touch or show lower heat signatures on a thermal scan, but this doesn’t mean their core temperature is better regulated. Their coat’s insulating barrier has been removed, increasing the risk of sunburn, heatstroke, and hormonal disruption.

4. Risks of Shaving and Short Scissoring Fur-Bearing Breeds

4.1 Post-Clipping Alopecia (PCA)

• Hair follicle damage can disrupt the natural growth cycle, leading to patchy regrowth or permanent hair loss.
• Hormonal sensitivities at the follicle level: The coat’s removal can interfere with localised hormone activity essential for hair growth.
• Breed predisposition (e.g. Pomeranians, Chow Chows, Huskies).
• Excessive scissoring even without shaving can cause PCA in sensitive breeds.

Once PCA occurs, regrowth may be slow, uneven, or permanent hair loss may occur.

4.2 Black Skin Disease (BSD)

Also known as Alopecia X, BSD is a progressive condition that results in:

• Hair loss
• Skin darkening (hyperpigmentation)
• Sensitivity and higher risk of infection

BSD may be triggered or worsened by shaving. Contributing factors include:

• Genetics
• Hormonal imbalances (e.g. hypothyroidism, Cushing’s disease)
• Nutritional deficiencies
• Repetitive grooming damage

Affected dogs often require lifelong skin and coat management.

5. Hormonal Impact of Clipping Double-Coated Breeds

While shaving doesn’t cause endocrine disorders like Cushing’s disease, it may impact local hormone signalling at the skin and follicular level, especially in predisposed breeds.

• Thyroid hormones, melatonin, and sex hormones play a role in hair cycling.
• Removing the coat alters environmental inputs (light, temperature), disrupting anagen-telogen cycles.
• Photoperiod signalling is reduced, delaying seasonal regrowth.

This may trigger coat cycle arrest in sensitive dogs — hair enters resting or shedding phase and does not return to growth.

6. Best Grooming Practices to Encourage Hair Regrowth

6.1 Avoid Further Clipping or Shaving

• No clipper work on affected areas
• Use scissors for hygiene only

6.2 Gentle Brushing and Stimulation

• Use soft bristle brushes or mitts
• Brush daily to promote blood flow
• Avoid aggressive de-shedding tools

6.3 Bathing and Skin Hydration

• Use gentle, natural shampoos (e.g., oatmeal, aloe)
• Keratin-boosting formulas may support follicle strength
• Follow up with moisturising sprays or leave-ins

6.4 Massage and Coat Recovery Treatments

• Use light circular motions
• Oils like coconut, emu, or argan can help stimulate skin
• Consider red light therapy (with veterinary guidance)

7. Nutritional and Supplement Support

7.1 Diet

• Feed high-quality, protein-rich diets with omega fatty acids
• Avoid artificial additives that may irritate skin

7.2 Supplements

• Biotin, B vitamins, Vitamin E, Zinc
• Collagen, gelatin, and essential oils
• Melatonin under veterinary direction

8. Creating a Long-Term Coat Recovery Plan

8.1 Consistency is Key

• Regrowth may take months or years
• Daily maintenance and owner education are essential

8.2 Monitor and Document Progress

• Use coat photos and grooming logs
• Work alongside a vet to rule out medical causes

Conclusion

Shaving a double coat compromises the dog's natural ability to regulate temperature, protect the skin, and maintain follicular balance. Conditions like PCA and BSD can be triggered or worsened by shaving and require patient, ongoing support.

Groomers play a vital role in helping owners understand coat health and promoting safe grooming techniques. By combining gentle care, nutrition, stimulation, and environmental awareness, we can support healthy coat maintenance and regrowth.
