Summer Coat Prep: When to Trim, When to Leave Length, and Why It Matters
The Short Summer Cut Isn't Always the Right Answer
Every June, client requests flood in for the same thing: "Take him short for summer." It's well-intentioned, but depending on the dog's coat type, shaving or trimming short can do more harm than good. Summer coat prep isn't a one-size-fits-all service — it's a coat-type-specific decision that requires you to push back on clients when necessary, explain your reasoning, and deliver results that actually keep the dog comfortable.
The short version: double-coated breeds should almost never be shaved. Single-coated breeds can often be trimmed down safely. And the in-between cases — your Doodles, your Bichon mixes, your heavily coated Spaniels — require a judgment call based on current coat condition, lifestyle, and what the owner is willing to maintain between appointments.
Double Coats: What Actually Happens When You Shave Them
A double coat — the kind you find on a Golden Retriever, Husky, Bernese Mountain Dog, or Labrador — consists of a soft, insulating undercoat and a coarser, protective topcoat (guard hairs). These two layers work together to regulate body temperature in both directions: they keep the dog warm in winter and create an insulating barrier against heat and UV radiation in summer.
When you shave a double coat down to the skin, you remove that entire system. The dog loses its natural sun protection and heat regulation. Worse, the undercoat often grows back faster than the guard hairs, leading to coat funk — a texture change where the coat comes in soft, cottony, and prone to matting. In some dogs, especially older ones or those with hormonal issues, the guard hairs never fully recover. This is sometimes called post-clipping alopecia, and it's a real risk you need to communicate to clients before putting a blade to a Husky.
The right approach for a double-coated dog in summer:
- Thorough deshedding with a high-velocity dryer and appropriate undercoat tools — a Furminator, undercoat rake, or slicker used properly removes the bulk of the dead undercoat that's trapping heat
- A light trim of feathering and sanitary areas where practical — tidying up without removing the protective topcoat
- Increased appointment frequency — every 6–8 weeks through summer instead of quarterly keeps the shed manageable and the coat functioning correctly
When a client insists on a shave anyway, document it. Note in the client record that you advised against it and they requested it over your recommendation. This protects you professionally if the coat comes back damaged.
Single Coats: When Trimming Short Actually Helps
Single-coated breeds — Poodles, Bichons, Shih Tzus, Maltese, most terriers — don't have the same dual-layer insulation system. Their coat grows continuously and doesn't shed seasonally. For these dogs, a shorter summer trim genuinely reduces heat retention and makes coat maintenance easier for the owner.
How short is appropriate depends on the breed and the coat's current condition. A Poodle in good coat can go to a #4F or #5F on the body comfortably in summer. A Bichon with a soft, open coat might mat more easily if left long in humidity. A Wheaten Terrier in full coat through a humid July is going to be uncomfortable — and miserable to comb out at the next appointment.
For single-coated dogs, summer prep typically means:
- Moving one or two blade sizes shorter than the client's usual cut
- Paying close attention to heavily feathered areas (ears, legs, underbelly) where heat and moisture accumulate
- Discussing maintenance expectations — a #7 on a Poodle looks very different from their typical Continental clip, and the client should understand that before you start

Doodles and Mixed Coats: The Problem Category
Goldendoodles, Labradoodles, Bernedoodles, and their cousins present a unique challenge because their coats don't follow predictable rules. Depending on which genetic traits dominate, you might be dealing with a wavy, low-shed coat that behaves more like a Poodle — or a thick, double-layer coat that behaves more like a Golden. Many fall somewhere in between.
The mistake groomers make is treating all Doodles the same. Here's a more accurate approach:
- Assess the undercoat first. Run your fingers through the coat near the base. If you feel dense, cottony undercoat under the wavy or curly topcoat, treat it more like a double coat. Don't shave without a thorough deshed first.
- Check the mat situation. A Doodle that comes in matted past the point of humane dematting gets shaved down regardless of season. The skin and coat health take priority. Document it, show the owner before if possible, and explain the shave-down protocol.
- Adjust for coat density, not breed name. Two Goldendoodles from the same litter can have completely different coats. Your blade choice should reflect what's actually on the dog, not what breed is printed on the intake form.
In summer, most Doodles with healthy coats do well trimmed to 1–2 inches on the body, with tighter trimming around the face, paws, and sanitary areas. This keeps airflow moving without removing whatever protective layer exists.
Heat Retention Zones: Where Groomers Can Make the Biggest Difference
Even when you're leaving overall length on a dog, targeted trimming in specific areas reduces heat retention significantly. These are the zones worth focusing on regardless of coat type:
| Zone | Why It Matters | Approach |
|---|---|---|
| Undercarriage / belly | Close to the ground, traps heat and moisture | Trim tight; #10 or #7 on belly strip where appropriate |
| Armpits and groin | High friction and sweat zones; prone to mat formation | Keep closely trimmed; check for early matting every visit |
| Ear canals and ear flaps | Warm, humid environment encourages yeast and bacterial growth | Keep ear canal hair clear; trim flap underside for airflow |
| Paw pads and between toes | Dogs regulate heat through their paws; interdigital hair traps debris and moisture | Trim flush between pads; keep tidy but don't over-strip |
| Face and muzzle | Panting is the primary cooling mechanism; heavy facial hair can obstruct airflow | Trim around mouth and nares; keep eyes clear |
How to Handle the "Just Shave Him" Client Conversation
You're going to have this conversation multiple times every summer. A client with a Husky or a Bernese drops off and says they want everything off. Here's a framework that works:
- Acknowledge the intent. "I completely understand — you want him to be more comfortable in the heat."
- Explain the mechanism briefly. "The problem is that this coat type actually insulates against heat, not just cold. Shaving removes the protection from the sun and can permanently change how the coat grows back."
- Offer the alternative with specifics. "What I'd recommend is a full deshedding bath and blowout — I'll remove the dead undercoat that's actually trapping heat, and I can tidy up the feathering. He'll feel noticeably cooler and we won't risk the coat."
- Let them decide, and document it. If they still want the shave, note it in the client record and proceed. You've done your job.
Most clients respond well to option three once they understand why. The ones who don't? That's their call as the owner. Your job is to inform, not override.
Timing Summer Prep Appointments Correctly
Summer coat prep isn't a one-visit event. The dogs that come in well-maintained through spring will be in much better shape for summer than those who skipped two appointments. If you're not already communicating seasonal scheduling to your regular clients, May is the time to do it.
For high-shedding double-coated dogs, a targeted deshedding appointment in late April or early May — before the peak summer heat — sets them up for the season. A follow-up 6–8 weeks later keeps the shed under control. Laying this out proactively also fills your summer calendar before clients start calling in July wondering why you're booked out three weeks.
Managing that kind of forward scheduling is much easier when your appointment calendar and client reminders are running automatically. If you're still doing it manually, tools like GroomBoard's 14-day free trial are worth a look — the SMS reminder system alone reduces the number of no-shows that blow up your carefully planned summer schedule.
A Few Coat-Type Quick References
When you're moving fast through a busy summer day, here's the cheat sheet:
- Huskies, Malamutes, Samoyeds: Deshed only. No shave. Explain every time.
- Golden Retrievers, Labs: Deshed, tidy feathering, sanitary trim. No body shave.
- Bernese Mountain Dogs: Same as above. Flag any matting behind ears and under arms.
- Standard, Miniature, Toy Poodles: Can go shorter — blade choice based on client preference and coat quality.
- Bichons, Maltese, Shih Tzus: Shorter summer cuts reduce matting risk, especially in humidity.
- Cocker Spaniels: Body coat can be taken shorter; ears and feathering trimmed for airflow and cleanliness.
- Doodle types: Assess coat individually. Deshed if undercoat is present. Trim to 1–2 inches if coat is healthy.
- Wire-coated terriers (Scottie, Welsh, Lakeland): Hand-strip or roll the coat ideally; if clipping, maintain length over the back for protection.
If you're looking at a breed you're less familiar with or want a deeper breakdown of a specific clip, managing difficult dogs during grooming and breed-specific guides are worth building into your reference library — the handling principles transfer across seasons.
