Introduction
Double-coated dog breeds — including Labradors, Golden Retrievers, German Shepherds, Siberian Huskies, and Border Collies — present a particular grooming challenge during summer months, as owners often face conflicting instincts about how to manage their dog's coat during hot weather. Understanding the genuine function of a double coat, why shaving is generally inappropriate despite seeming intuitive, and the grooming approaches that actually support comfort during summer heat helps you make informed decisions for your specific dog.
Quick Summary: Double coats provide genuine insulation against both heat and cold, and shaving typically does not help with cooling — it can actually increase sunburn risk and disrupt natural temperature regulation. The most effective summer grooming approach is thorough deshedding to remove loose undercoat, supporting the coat's natural cooling function rather than removing it entirely.
Understanding the Double Coat's Function
A double coat consists of two distinct layers: a dense, soft undercoat that provides insulation, and a longer, coarser outer guard coat that provides weather protection and helps regulate the dog's temperature. Critically, this coat structure provides insulation against heat as well as cold — the same mechanism that keeps a double-coated dog warm in winter also helps regulate their body temperature in summer by creating an insulating layer of air between the skin and the external environment, somewhat moderating the direct heat exposure the skin would otherwise experience.
Why Shaving Is Generally Not Recommended
Despite seeming intuitively helpful for keeping a double-coated dog cool, veterinary and grooming professional consensus generally advises against shaving double coats for several specific reasons:
Disrupted Natural Cooling Function
Removing the coat entirely eliminates the natural insulating air layer that helps moderate temperature, potentially making the dog more vulnerable to heat absorption directly onto the skin rather than less so, contrary to the intuitive assumption that less coat automatically means better cooling.
Increased Sunburn Risk
A shaved double-coated dog has minimal protection from direct sun exposure, significantly increasing the risk of sunburn, particularly on lighter-skinned areas, which can be genuinely painful and increase long-term skin cancer risk with repeated sun damage over time.
Potential for Coat Damage
Double coats, once shaved, do not always regrow in the same pattern and density as before — some dogs experience uneven regrowth, or a permanently altered coat texture and pattern, sometimes referred to as 'coat funk' or post-clipping alopecia, which can be a frustrating, sometimes permanent cosmetic change beyond the immediate summer season's concerns.
Reduced Protection From Insect Bites and Minor Injuries
The coat provides a degree of physical protection from insect bites, minor scrapes, and general environmental contact that becomes absent with significant coat removal.
What Actually Helps: Thorough Deshedding
Rather than removing the coat entirely, the genuinely effective summer grooming approach for double-coated breeds is thorough, regular deshedding — removing the loose, dead undercoat that would otherwise trap excess heat against the skin, while preserving the structural integrity and protective function of the remaining, properly maintained coat.
Why Deshedding Helps
A coat full of loose, dead undercoat traps heat considerably more than a coat that has been thoroughly groomed to remove this excess material. Loose undercoat reduces the airflow that supports the coat's natural cooling function, effectively working against the insulation mechanism rather than supporting it. Thorough deshedding restores the coat's intended function, allowing it to work as designed rather than being compromised by excess trapped material.
The Deshedding Process
- Begin with a thorough brush-through using a slicker brush to address the outer coat and any surface tangles
- Follow with an undercoat rake or de-shedding tool specifically designed to reach and remove the dense undercoat that a standard brush alone cannot adequately address
- Work through the entire body systematically, paying particular attention to areas where undercoat tends to accumulate most densely — typically the back, sides, and rear
- Increase frequency during peak shedding season, which for many double-coated breeds intensifies notably as the transition into summer occurs, sometimes called 'blowing coat'
Supporting Tools for Effective Summer Grooming
The ROJECO Pet Spray Brush supports this seasonal grooming need effectively — its integrated misting function helps reduce static and can provide a refreshing, cooling sensation during grooming sessions in warm weather, while supporting thorough loose hair removal. For dogs requiring particularly thorough detangling alongside deshedding, the ROJECO Chick Pet Spray Comb combines moisturising mist with effective combing, valuable for working through any denser areas of coat requiring extra attention during intensive summer deshedding sessions.
Bathing Considerations for Summer
Regular bathing, combined with thorough deshedding, supports overall coat and skin health during summer months. A bath can help loosen and remove additional dead undercoat that brushing alone might not fully address, with subsequent brushing during the drying process catching loosened hair before it falls out naturally around your home.
The ROJECO Automatic Pet Bubble Machine makes summer bathing sessions more efficient, while the ROJECO Smart Pet Dryer Box ensures thorough drying afterward — particularly important for double-coated breeds, where retained moisture deep within the dense undercoat can create an environment conducive to skin irritation or hot spots if not addressed through complete, thorough drying.
Additional Summer Comfort Strategies Beyond Grooming
While appropriate grooming plays a meaningful role in summer comfort, it works best alongside broader heat management strategies:
- Adjusting exercise timing to cooler parts of the day, avoiding peak heat hours
- Ensuring constant access to fresh, cool water
- Providing shaded retreat areas, both outdoors and ensuring adequate indoor ventilation
- Recognising early signs of heat-related distress and responding promptly
When Trimming (Not Shaving) May Be Appropriate
While full shaving is generally discouraged for double-coated breeds, modest, professional trimming of certain areas — particularly around the feet, ears, or sanitary areas — for hygiene and practical purposes differs from full-body shaving and does not carry the same concerns regarding coat function disruption. This distinction matters: targeted, modest trimming for specific practical purposes is quite different from removing the protective double coat structure entirely across the whole body.
Breed-Specific Considerations
While the general principles discussed apply broadly across double-coated breeds, individual coat density, specific breed standards, and any particular skin sensitivities can vary. If you are uncertain about the appropriate summer grooming approach for your specific dog's breed and individual coat characteristics, consulting a professional groomer experienced with your particular breed, or your vet, can provide tailored guidance beyond these general principles.
Conclusion
Summer grooming for double-coated breeds centres on thorough, regular deshedding to remove excess loose undercoat — supporting the coat's natural, genuinely functional cooling mechanism — rather than shaving, which typically disrupts this function and introduces additional risks including sunburn and potential coat damage. Combined with broader heat management strategies, appropriate seasonal grooming helps double-coated dogs remain genuinely comfortable throughout the warmest months while preserving their coat's long-term health and protective function.
