You'll know the exact morning it starts. One day your husky is fine, the next there's a tumbleweed of grey fluff drifting across the kitchen floor and a fresh layer on your black coat by the door. Welcome to spring in Montreal, where the snow finally lets up and your double-coated dog decides to redecorate the whole condo in fur. We see it roll through the daycare every April like clockwork, dog after dog arriving a little fluffier than they should, owners holding a brush they clearly haven't touched since October. So let's talk about dog shedding season, why spring hits double coats so hard here, and what actually helps. (Hint: not the clippers.)
Why April flips the switch
Here's the part that surprises people. The big spring coat blow doesn't wait for warm weather. It kicks off while it's still cold and grey out, because the real trigger isn't temperature, it's daylight. The Merck Veterinary Manual explains that shedding responds to both temperature and photoperiod, the length of the day, and that most animals shed in early spring and early autumn. Montreal's days lengthen fast through March and April, so your dog's body starts dumping its winter undercoat well before it feels like spring outside.
And the timing lines up almost perfectly with our thaw. According to Environment Canada's climate normals, the mean daily temperature here jumps from minus 2 in March to plus 6.4 in April, making April the first month of the year that sits above freezing. That same data shows April still averages about 13 cm of snow, so this isn't an overnight switch. It's a few messy weeks. Your dog spent all winter packing on a dense undercoat to survive a city that averages 209 cm of snow a year, and now all of it has to come out.
Which dogs actually blow their coat
Not every dog does this. Shedding season is really a double-coat thing. A double coat has two layers, a topcoat of long coarse guard hairs over a soft, dense undercoat that traps warm air in winter and, weirdly, cool air against the skin in summer. The American Kennel Club lists the usual suspects: Labs, Golden Retrievers, both kinds of Corgi, Border Collies, Aussies, Bernese Mountain Dogs, Newfoundlands, Great Pyrenees, plus the Arctic crew like Samoyeds, Pomeranians and Malamutes. VCA notes these heavy-undercoat dogs typically go through two big seasonal sheds a year, late spring and late fall. If you've got one of these, spring is your season. If you've got a poodle or a shih tzu, you can mostly relax and read on out of solidarity.
Brush more, brush smarter
The honest truth about shedding season is that there's no magic off switch. The fur is coming out either way. Your only real choice is whether it ends up on a brush or on your sofa, so this is the time of year to step it up. The AKC's shedding guide recommends scaling brushing from once a week up to a few times a week, and right up to daily during the heavy stretch. When it really peaks, swap your everyday brush for a coat rake or shedding tool and run it along the coat in the direction the hair grows, never against it.
Tool-wise, VCA specifically points to a long-toothed comb, ideally one with offset rows of tines, for pulling those tangled clumps of loose undercoat out during a seasonal shed. There's a nice bonus to all this brushing too. VCA says daily brushing cuts down how much loose hair your dog swallows while self-grooming, and keeps less of it floating around the house. For double coats generally, the AKC's grooming advice is a slicker brush followed by a comb to lift the dead hair and spread the natural oils around, with one small but important detail: you're brushing the hair, not scraping the skin underneath.
Please don't shave the double coat (yes, even now)
Every spring someone asks us to "just shave it all off and start fresh." We understand the impulse. The fur is everywhere and it feels like the obvious fix. It is not the fix, and here's the part that breaks our hearts a little: shaving doesn't even stop the shedding. Dr. Jerry Klein, the AKC's chief vet, explains that clipping a double coat strips out the insulating layer, leaves the dog open to sunburn and actually raises its skin cancer risk. Worse, the undercoat grows back faster than the guard hairs and crowds them out, so the coat can come back patchy, a different texture, sometimes even a different colour than before.
The grooming pros agree. The AKC is clear that you should never shave a double-coated dog unless the matting is so bad that the skin underneath genuinely can't dry out. Outside of that, you're just damaging the topcoat and inviting skin problems, all while the dog keeps shedding anyway. (If your worry is keeping your dog cool for summer, that's a different conversation, and dogs cool themselves by panting, not through their skin, but we've covered the heat side of things separately.) The short version: brush it out, don't buzz it off.
When the brush isn't winning
Some springs, the home brush just can't keep up. The undercoat packs down faster than you can rake it out, you start seeing mats form behind the ears and on the back legs, and brushing turns into a battle nobody enjoys. That's the moment a professional de-shedding treatment earns its keep. A proper de-shed with the right high-velocity dryer and tools pulls out the loose undercoat in one session in a way a hand brush at home just can't match, and your dog goes home lighter, shinier, and shedding a fraction of what it was.
One rule we never break, and you shouldn't either: brush before the bath, not after. The AKC's spring grooming guide puts it plainly. Bathe a dog with mats still in the coat and the water only tightens them up, making everything harder to brush out. That same source suggests bathing roughly every three weeks through spring during the heavy shed. Our Bath & Tidy is built for exactly this, a warm bath, a full brush-out and a light tidy, and you can add the de-shed right on top. There's a quieter benefit too. The AKC notes that a certified groomer's hands on your dog every few weeks often catch skin and ear issues early, the kind of thing that's easy to miss under all that fluff at home.
When shedding isn't just spring
Heavy shedding in early spring and early fall is completely normal for a double coat. What's not normal is shedding that shows up at the wrong time of year, or comes with company. PetMD flags a vet visit if you see bald patches, skin lesions or discoloration, constant itching, weight changes, or hair that looks dull, dry and broken, since those can point to allergies, parasites, a hormonal issue or an infection rather than a simple seasonal blow. When in doubt, your vet is the right call. A spring de-shed makes those changes easier to spot, but it isn't a substitute for a checkup.
One more spring to-do while you're at it
Once your freshly de-shedded dog is ready to head back to the dog run, give the paperwork a glance. A Montreal dog licence runs 31.80 dollars a year, it has to be renewed annually, and the tag has to be worn at all times. It matters more than you'd think come spring, because the city's more than 65 dog parks are the only public spots where your dog can legally run off-leash, and your dog needs a valid licence to be out and about in the city anyway. Nothing like a clean, light coat and an up-to-date tag to kick off patio-and-park season right.
