There are two kinds of owners when a Brisbane morning hits 32°C before nine – the ones who book a full shave-down to help the dog cool off, and the ones who learnt the hard way that a bare coat usually makes the heat worse. A good summer haircut isn’t about taking everything off. It’s about matching the cut to the coat, because the trim that suits a cavoodle is the wrong call for a husky.
Get the coat type right and the rest follows. Get it wrong and you can leave a dog hotter, sunburnt and – for some breeds – with a coat that never grows back the same. So before you pick a style off the groomer’s wall, work out which of two coats your dog is carrying.
The best summer haircut depends on your dog’s coat, not the calendar. Single-coated breeds like poodles and cavoodles can go to a short, even ‘puppy cut’ of about 2 to 4cm. Double-coated breeds – huskies, retrievers, Samoyeds – should be deshedded and tidied, never shaved. Leave at least 2cm to guard against sunburn, and trim the belly and paws for airflow.
The best summer haircut starts with coat type
Almost every summer grooming mistake starts here. Single-coated dogs grow one layer of hair that keeps coming, a bit like ours – poodles, cavoodles, maltese, shih tzus, bichons and most ‘oodle’ crosses. There’s no insulating undercoat, so a sensible trim genuinely helps them in the heat.
Double-coated dogs are the opposite story. A soft, dense undercoat sits beneath longer guard hairs, and together they regulate temperature in both directions. Huskies, golden retrievers, Labradors, border collies, Samoyeds and most working breeds carry this coat. The undercoat you’re itching to remove is the bit doing the cooling.
Single-coat breeds: cuts that work in an Aussie summer
This is where a summer cut earns its name. For curly and wool-coated dogs the most popular warm-weather option is the puppy cut – one even length all over, usually around 2 to 4cm, short enough to cut drying time and matting, long enough to shade the skin. A ‘teddy bear’ trim keeps the body short and leaves the face a little fuller, and it still works in the heat. For a miniature poodle or a cavoodle, ask the groomer for a short ‘summer puppy cut’ rather than naming a clipper number, and mention if your dog spends part of the day outdoors.
Maltese and shih tzus do well with a short body and tidy feet. Wire-coated breeds sit in between – a miniature schnauzer keeps its harsher, weather-resistant jacket if it’s hand-stripped, but most pet owners clip for convenience and accept a slightly softer result. Either way, summer is the season to keep legs and belly tidy so air can move.
Double-coat breeds: deshed, don’t shave
Here’s the rule we’d tattoo on every clipper if we could – never shave a healthy double coat to cool a dog down. The undercoat traps a layer of cooler air against the skin and the guard hairs block the sun, so the coat acts as insulation in summer as much as winter. Strip it off and you remove the dog’s own cooling system, raise the sunburn risk, and on breeds like the husky or Labrador you can trigger patchy regrowth that, in some dogs, never fully recovers.
The fix is deshedding, not shaving. A solid deshed with an undercoat rake or a deshedding tool like a Furminator pulls out the dead undercoat that’s actually trapping heat, while the protective topcoat stays put. A groomer’s force-dryer does the same job faster on a heavy coat like a Samoyed. Most double-coated dogs need this every few weeks through spring and summer, more often during the big seasonal ‘coat blow’.
The climate-smart summer trim, step by step
Order matters more than owners expect, and skipping a step is where most at-home jobs go wrong. Here’s the sequence we use.
- Brush and detangle first. Work through the coat before any water touches it (this is the bit most owners skip). Wet mats tighten and become impossible to comb. Allow 5 to 15 minutes depending on length.
- Deshed if double-coated. Use an undercoat rake to clear the dead fluff while the coat is dry. On a big coat this takes 10 to 20 minutes and removes the layer that traps heat.
- Bathe in warm water. Warm, around body temperature – never hot. Use a dog shampoo, not a human one, since our skin sits at a different pH. Rinse until the water runs clear.
- Dry fully before any clipping. Clipping a damp coat drags and leaves tracks. On small dogs keep a force-dryer on low heat, or skip the heat and use airflow only.
- Clip or trim to length – single coats only. Take curly and wool coats to your chosen length (2 to 4cm is a safe summer default). Double coats get tidied, not clipped down.
- Finish the cooling zones. Trim the belly, the groin and the hair between the paw pads, and do a light sanitary trim. The belly is a key heat-release area, so a neat trim there helps every coat type.
How short is safe – and how often
There’s a floor you shouldn’t go under. Leave at least 2cm (about an inch) on most dogs – shorter than that and you expose pale or thin-coated skin to sunburn, insect bites and irritation. Dogs with white or pink skin, like many maltese and some cavoodles, burn faster than owners think.
On timing, most single-coated dogs need a trim every 6 to 8 weeks to stay comfortable, a touch more often in peak summer. Double coats don’t get clipped on a schedule at all – you deshed them little and often instead, usually fortnightly when they’re dropping coat. In most cases a 10-minute brush twice a week does more for summer comfort than any single big haircut.
Common summer grooming mistakes
A few errors come up again and again once the weather turns:
- Shaving a double coat to the skin to cool the dog down. It does the opposite and can wreck the coat for good.
- Going too short on a pale or fine-coated dog and ending up with a sunburnt back two days later.
- Bathing before brushing, so every small tangle felts into a mat the moment it gets wet.
- Running a high-heat force-dryer on a small or flat-faced dog, which adds heat stress on a day that’s already hot.
- Booking a beautiful summer trim, then walking the dog on a 4pm footpath that’s still radiating the day’s heat.
The Australian bit: heat, footpaths and the groomer bill
Australian summers don’t behave like the northern-hemisphere ones most grooming blogs are written for. Add the humidity through Queensland and the Top End and you get a hot-spot and matting season that runs for months. The Australian Veterinary Association is blunt about heat risk – a clipped coat won’t save a dog left in a parked car, where temperatures can climb well past anything safe within minutes.
A fresh trim does nothing for the paws, either. Bitumen and concrete can sit far hotter than the air, and if you can’t hold the back of your hand on the path for seven seconds, it’s too hot to walk – trim or no trim. Stick to early-morning and after-dark walks on the grass through the worst of it.
On cost, a salon groom for a small single-coated dog runs roughly $60 to $120 in metro areas in 2026, while a mobile groomer who comes to you usually sits around $80 to $150. A proper deshed treatment for a big double coat often costs more again because of the time involved. If you’re booking a pro, look for one accredited through the Pet Industry Association of Australia – it’s a reasonable signal they’ve been trained on coat types, not just clippers.
When a summer cut becomes a vet visit
Some things are past the point of a DIY trim, and a few are past the groomer too. Book a professional or your vet if you see:
- Mats packed tight to the skin, especially behind the ears or under the legs – cutting these at home risks nicking the skin.
- Red, weepy or smelly patches under the coat, which can be hot spots that need treatment, not just a wash.
- A persistent ear smell or constant head-shaking, or scratching that doesn’t settle after grooming.
- Cracked or blistered paw pads, or limping after a walk on a hot surface.
- Heavy panting, drooling, wobbliness or collapse in the heat – treat this as an emergency and cool the dog on the way to the vet.
One more: leave the anal glands to a groomer or vet. It’s not a routine home job, and you should only flag it if your dog is scooting or licking at the area.
FAQ
Should I shave my dog in summer?
No, not if your dog has a double coat (like a husky, retriever, or collie). Shaving removes the insulating undercoat that helps regulate their temperature and exposes their skin to sunburn. For single-coated breeds (like poodles or maltese), a short trim is fine, but never shave down to the skin.
How short should I cut my dog’s hair in summer?
Leave at least 2cm (about an inch) of hair to protect the skin from sunburn and insects. For single-coated breeds, a ‘puppy cut’ of 2–4cm is ideal. Double-coated breeds should not be clipped short at all—focus on deshedding instead.
Does a summer haircut actually keep my dog cooler?
For single-coated breeds, yes—a shorter coat reduces drying time and matting, improving airflow. For double-coated breeds, no—their coat is designed to insulate against heat, and shaving it can make them hotter. Regular deshedding is the key to keeping them cool.
How often should I groom my dog over summer?
Single-coated dogs typically need a trim every 6–8 weeks. Double-coated dogs don’t need clipping, but they benefit from deshedding every few weeks during coat-blowing seasons. Brushing twice a week helps manage shedding and keeps the coat healthy.
