Why Your Dog Sheds More in Autumn (And How to Stay Ahead of It)

The Thorncombe Team · 8 min read · Last updated May 2026

If you live in NZ and own a dog, you've probably noticed the fur pile under the couch doubled sometime in March. That's autumn shedding — and most Kiwi owners are surprised by just how heavy it gets. Here's the science behind it, why NZ dogs shed differently than Northern Hemisphere dogs, and the exact grooming routine that gets you through it without losing your mind (or your carpet).

Why dogs shed more in autumn — the short answer

Answer firstDogs shed in autumn because shortening daylight hours trigger their hormones to swap out the lighter summer undercoat for a denser winter one. This biannual "coat blow" is genetically programmed, peaks over 2–4 weeks, and is heavier than the spring shed in most double-coated breeds. The fix is more frequent brushing (3–5 times a week), the right tools for your dog's specific coat, and supporting skin health from the inside.

The trigger isn't temperature — it's photoperiod (day length). As days shorten through March and April in NZ, your dog's pituitary gland reduces melatonin production, which signals follicles to release the summer undercoat and grow in heavier winter fur. This is true even for dogs who live entirely indoors with steady artificial lighting, because evolutionary patterns are stubborn.

Single-coated breeds (Poodles, Bichons, Maltese) shed minimally year-round and have less dramatic seasonal swings. Double-coated breeds (Huskies, Labradors, German Shepherds, Border Collies, Golden Retrievers, Staffies) "blow coat" twice a year — and autumn is usually the heavier of the two.

What "blowing coat" actually looks like in NZ

Answer first"Blowing coat" is when a dog releases a large volume of undercoat over a short period — typically 2–4 weeks of heavy shedding, with a longer 6–8 week tail of moderate shedding. In NZ this usually starts in late March and runs through April–May for autumn, and August–September for spring.

Owners who haven't experienced a full coat blow before are sometimes alarmed by the sheer volume. A medium Lab or Staffie can drop enough undercoat in a single brushing session to fill a small shoebox. This is normal. What's not normal is bald patches, irritated skin, or shedding that doesn't slow down after 6 weeks — those warrant a vet check.

Timing in different parts of NZ

Climate variation across NZ shifts the timing slightly. Auckland and the upper North Island tend to start shedding later (mid-April through May) because temperatures drop more gradually. Wellington and the South Island typically see it earlier (mid-March through April). The Waikato — our patch — is somewhere in between, with most owners noticing peak shedding in the second half of April.

The autumn brushing routine that actually works

Answer firstBrush double-coated dogs 3–5 times per week during peak autumn shed (April–May), using an undercoat rake or deshedding tool for the bulk of the work and a slicker brush to finish. Single-coated dogs need brushing 1–2 times per week. Sessions should last 10–15 minutes and end before the dog gets restless.

The biggest mistake we see is using the wrong tool. A slicker brush on a Husky's blown coat will exhaust you and barely scratch the surface. An undercoat rake on a Poodle will damage the coat. Match the tool to the coat:

Coat type Examples Best tool Brush frequency
Short double coat Lab, Staffie, Beagle Deshedder + rubber curry 3–4× per week
Long double coat Golden, Husky, Border Collie Undercoat rake + slicker 4–5× per week
Smooth single coat Frenchie, Boxer, Whippet Rubber curry + soft bristle 2× per week
Curly / wool coat Poodle, Cavoodle, Labradoodle Slicker + comb (NO rake) 3× per week (also clipping)
Wire coat Schnauzer, Terriers Stripping knife + slicker 2× per week + hand stripping

The 10-minute routine

Set a timer. Most owners over-groom by trying to "get it all" in one session, which makes the dog hate it. Better to do 10 focused minutes 4 times a week than 45 minutes once and dread it.

  1. 2 minutes — rubber curry all over to lift dead hair to the surface
  2. 5 minutes — undercoat rake or deshedder along the back, flanks and rear (the densest areas)
  3. 2 minutes — slicker brush to clear what the rake lifted
  4. 1 minute — comb to check there's no remaining matting, especially behind ears and on the rear legs

Skin health is what's actually under the fur

Answer firstHeavy seasonal shedding is partly a skin event, not just a fur event. Supporting skin with omega-3 fatty acids (fish oil or green-lipped mussel), reducing bath frequency to once every 4–6 weeks during shed season, and using a moisturising shampoo prevents the dry, flaky skin that makes shedding worse.

Owners often over-bathe during shedding season trying to "get the loose fur out". The opposite usually helps — frequent bathing strips natural oils, dries the skin, and makes the coat more brittle. If you do bathe during shed season, use a moisturising oatmeal-based shampoo and condition every time.

Diet matters too. Omega-3 fatty acids reduce inflammation and support the coat from the inside. Adding a green-lipped mussel supplement (a NZ native ingredient with strong evidence behind it) or salmon/fish oil to your dog's food can noticeably improve coat condition within 4–6 weeks. It's not magic — it's nutrition the average dry food doesn't provide enough of.

What we use at home The Thorncombe team's own dogs (Staffies and Frenchies) get a daily fish oil capsule from late March through mid-May, plus a brushing session every second night during peak shed. The Frenchies are smooth-coated but still drop fine white hairs that get into everything — the rubber curry plus a damp microfibre cloth handles it.

Living with the fur — practical NZ home tips

No amount of brushing eliminates shedding — it just controls it. The other half of the battle is managing fur in your home:

  • Use vet bedding as a "fur magnet" in the dog's bed area. Loose fur sinks into the fibres rather than floating around the house. Shake and vacuum the bedding twice a week during shed season.
  • Damp microfibre cloths beat dry vacuuming for hard floors. The static lifts fine fur instead of pushing it around.
  • Lint rollers for clothing — buy in bulk, keep one in the car, by the door, and in the bathroom.
  • A rubber broom on carpet works better than a vacuum for getting embedded undercoat out.
  • Wash dog bedding weekly during peak shed. UK vet bedding (dry bed) handles high-temperature wash cycles without breaking down.

When shedding is a problem, not a season

Answer firstExcessive shedding is a vet question, not a grooming question, if you see: bald or thinning patches, red or inflamed skin, dandruff in clumps, an oily or rancid smell, shedding that doesn't slow after 8 weeks, or shedding outside seasonal windows (e.g. heavy shedding in mid-winter or mid-summer). These can indicate allergies, hormonal conditions like hypothyroidism, parasites, or nutritional deficiency.

For most healthy dogs, the autumn shed is intense but uneventful. If your dog is shedding in chunks, leaving bald patches, or scratching constantly, that's not a brush problem — that's a vet visit. Don't let "it's just the season" become a reason to delay a check-up.

Frequently asked questions

How long does autumn shedding last in NZ dogs?
Peak shedding typically lasts 2–4 weeks, usually somewhere between late March and mid-May depending on your region. There's often a longer 6–8 week tail of moderate shedding that gradually slows as winter sets in.
Can I bath my dog to speed up the shed?
Sometimes — a warm bath followed by thorough brushing can release a lot of loose undercoat in one session. But more than one bath every 3–4 weeks during shed season can strip skin oils and make things worse. Brushing is always the better lever.
Do all dogs shed in autumn?
No. Single-coated breeds like Poodles, Bichons, and most "doodles" shed minimally year-round and don't have a dramatic seasonal blow. Hairless breeds obviously don't either. Double-coated breeds shed most heavily — and most NZ dogs (Labs, Staffies, Goldens, working breeds) are double-coated.
What's the best brush for a Staffie's autumn shed?
A rubber curry brush is the most effective tool for short double coats like Staffies. Used in circular motions, it lifts the loose undercoat to the surface where it can be wiped or vacuumed away. A deshedder used sparingly (once a week, not daily) is also helpful for peak shed weeks.
Does adding omega-3 actually reduce shedding?
It doesn't reduce the volume of seasonal shed — that's hormonal. But it does improve coat condition, reduce inflammation, and prevent the dry, brittle hair that gets shed more frequently outside of seasonal cycles. Most owners see noticeable coat quality improvement within 4–6 weeks of daily supplementation.
Should I shave my dog to help with shedding?
No — never shave a double-coated dog. The coat regulates temperature in both directions, and shaving can permanently damage how the coat regrows. Single-coated dogs can be clipped safely (and many need it). When in doubt, ask a groomer who knows your breed.
