Every September and October, double-coated dogs dump their summer undercoat all at once. Here is which breeds do it, why it happens, and the 15-minute weekly routine that actually keeps the fur off your floors.
The heaviest blow on this list. The undercoat comes out in sheets you can pull free by hand.
Sheds all year, then doubles down in fall. Owners call them german shedders for a reason.
A small dog with a big dog's undercoat. The volume of fur per pound is shocking the first time.
A dense medium coat that mats where the blown undercoat gets trapped, especially behind the ears and in the pants.
The feathering hides how much undercoat is releasing until it is all over the couch.
A short coat fools people. Labs carry a true double coat and blow it on schedule like the rest.
Any dog with a double coat is on this list, these are just the ones we see most. The linked breeds have full bathing guides with schedules and prices.
Coat blow is triggered by photoperiod, the shortening of the days. As daylight drops through September, hormones tell the coat to swap the light summer undercoat for a dense winter one, and the old undercoat releases in bulk to make room. Temperature has almost nothing to do with it, which is why a husky in a 75 degree San Jose October blows coat exactly on schedule.
This is also why you cannot wait it out by keeping the house cool or warm. The blow runs its course over two to six weeks no matter what. The only lever you control is how much of that released fur you remove on purpose, versus how much your vacuum meets later.
Work with the coat direction, whole body, light pressure. The rake's job is to lift the dead undercoat out from under the topcoat. This is where most of the fur comes from.
The slicker picks up what the rake loosened and tidies the topcoat. Slicker-only brushing skims the surface and misses the actual blow, which is why brushing can feel useless if the order is wrong.
Part the coat to the skin with one hand and brush the exposed line, then move up an inch and repeat. Do the pants, the ruff, and behind the ears. It is slower, and it is the only way a brush reaches the base of a dense coat.
The same routine, shorter sessions. Two to six weeks of daily brushing beats one heroic weekend session, because the coat releases on its own schedule, not yours.
Never shave a double coat. The coat is the dog's insulation and sun protection, shaving often ruins how it grows back, and the shedding does not stop anyway. Remove the dead undercoat, keep the coat.
The weekly routine handles a normal shedding month fine. Mid-blow is different, because a brush only reaches the outer layer of a coat that dense. A deshed bath works deeper: warm water and a deshedding shampoo with soak time loosen the dead undercoat at the skin, and then a high-velocity dryer pushes air down to the skin and blasts the released fur out in sheets. That is depth no brush and no home dryer can reach.
One deshed session in the middle of a blow removes the bulk of the loose undercoat in about an hour, in the van, so the fur stays with us instead of in your bathroom. Prices run $55 to $95 by dog size, flat. Two or three visits usually cover an entire fall blow.
The schedule builder knows the double-coat calendar. Answer a few questions about your dog and it turns the blow-season cadence into dates you can put on the calendar.
