Quick answer: dogs and cats "blow coat" in September and October — they drop the light summer coat to grow a dense winter undercoat, which means 2–4× more loose fur for about 4–6 weeks. It's completely normal, and a 15-minute weekly routine (below) keeps it off your couch, clothes and car.
Why do pets shed more in fall?
Shedding is triggered by daylight, not temperature. As days get shorter, your pet's body starts pushing out the thin summer coat to make room for winter insulation. Double-coated breeds — golden retrievers, huskies, German shepherds, and most cats — shed hardest. Indoor pets under artificial light shed a bit year-round, but most still spike in fall.
How long does fall shedding season last?
Typically 4–6 weeks, peaking mid-September through October. If heavy shedding runs past 8 weeks, comes with bald patches, or the skin looks red or flaky, that's not seasonal — see our guides on why cats overshed and reducing dog shedding, and check with your vet.
The 15-minute weekly fall routine
- Deshed at the source (2 × 5 min): two short sessions with the Furly Deshedding Glove ($24.99) pull the loose undercoat out before it lands on your furniture. Most pets treat it like petting.
- Rake the carpet (3 min): the Copper Rake ($19.99) combs woven-in fur up out of carpet, stairs and car mats — the stuff vacuums skim over.
- Roll the couch (2 min): the Fur Roller ($24.99) sweeps sofas and bedding with no refills to buy.
Fur on your clothes as you head out the door? The Static Mitt ($16.99) lifts it in one pass.
Should I bathe or shave my pet during coat blow?
A warm bath mid-blow can loosen a lot of coat at once (brush before and after). Never shave a double-coated dog or cat — the undercoat is their insulation for winter and summer, and it often grows back patchy.
FAQ
When does fall shedding start? Usually early-to-mid September in the US, as daylight noticeably shortens.
Do indoor cats have a fall shed? Yes, usually milder — artificial light spreads their shed out, but most still spike in fall.
Does deshedding actually reduce loose fur? Yes — removing undercoat at the source means it never reaches your furniture. Here's how deshedding gloves work.
What's the fastest way to get fur out of carpet? A carpet rake beats vacuuming alone — full method in our carpet guide.
