Dog Care
That sudden explosion of fur every September isn't triggered by cold weather. It's triggered by the days getting shorter — which means it's predictable enough to prepare for.

Whether your dog lives through a Prairie fall, a coastal B.C. fall, or a Maritime fall, they all hit their big seasonal shed around the same time of year — because the trigger isn't weather, it's daylight. Shrinking daylight hours signal a hormonal shift that tells your dog's body to drop the lighter summer undercoat and start growing a denser winter one.
Because it's daylight-driven and not weather-driven, this is one seasonal change you can see coming — and stock up for.
Why coat blow catches owners off guard
Most owners notice the fur first and reach for a brush after the fact. In reality, it's one of the most predictable seasonal events in a dog's year.
- Double-coated breeds feel it most. Dogs with a distinct undercoat — think Huskies, Shepherds, Retrievers — shed the heaviest volume during this transition.
- Skin gets stressed too. A fast coat turnover pulls a lot of resources from the skin, which is why coats can look dull or flaky right when shedding peaks.
- It's predictable, not random. Because it's daylight-driven, you can expect it in roughly the same calendar window every year — worth having your kit ready ahead of time.
Have your coat-blow kit ready before it starts
Growing a whole new coat in a short window takes a lot out of the skin and hair follicles. Starting an omega-3 and omega-6 supplement a few weeks before shedding peaks gives the new coat a head start, rather than trying to repair a dull, brittle coat after the fact.
The same goes for grooming tools — having a good deshedding brush already in the house means you can start clearing the old undercoat the moment it lets go, instead of hunting for one mid-shed while fur piles up on the floor.
Fall coat-blow checklist
- ✓ Omega-3/omega-6 skin & coat supplement, started early
- ✓ Deshedding brush or comb suited to your dog's coat type
- ✓ Hydrating shampoo & conditioner on hand for bath day
- ✓ Joint supplement ready for cooler-weather stiffness
Think of fall coat blow as a season to stock up for, not a mess to clean up after. A little preparation ahead of time keeps it from turning into weeks of dull fur and constant vacuuming.
