Why is my dog shedding more than usual in autumn?

Overview
It’s fairly common for dogs to shed more in autumn as they change coat for the colder months. In many cases, this is a normal seasonal coat blow, but excess shedding can also happen if the coat is dry, the grooming routine has changed, or there’s an underlying skin issue.
Things To Check
1. Check whether the shedding is seasonal, or whether it’s happening all over the coat, suddenly, or in patches.
2. Look closely for redness, flaking, scabs, broken hair, a greasy coat, or any sore-looking areas.
3. Feel for dandruff, dryness, or a dull coat, which can make loose hair seem more noticeable.
4. Notice whether your dog is scratching, licking, rubbing, or seeming uncomfortable more than usual.
5. Think about any recent changes in diet, shampoo, grooming routine, home heating, or time spent outdoors.
6. Check for fleas or other signs of parasites, especially if your dog is scratching or chewing at the skin.
7. Make sure the coat isn’t matted, as trapped loose hair can build up and come out in bigger clumps when brushed.
Common Causes
The most common reason is a normal seasonal coat change. Many dogs shed their lighter summer coat in autumn as they grow a denser winter coat.
Dry indoor heating, low humidity, or less frequent grooming can also make shedding more obvious, especially in double-coated breeds.
Skin irritation, fleas, allergies, or minor skin infections can lead to extra shedding too, particularly if the coat looks irritated or your dog is itchy.
Less commonly, hormone changes, poor coat condition, or another health issue may be involved, especially if the shedding is heavy, ongoing, or comes with other signs.
What To Do
Brush your dog more regularly during autumn to remove loose hair before it ends up around the house or becomes tangled in the coat.
Use a grooming routine that suits your dog’s coat type, and keep it gentle if the skin looks dry or sensitive.
Keep an eye on the skin as you groom, because changes like redness, soreness, flakes, or scabs can help you spot a problem early.
Make sure your dog’s diet, parasite control, and exercise routine are steady, as sudden changes can sometimes show up in the coat first.
If the shedding seems out of proportion, is patchy, or keeps getting worse, book a vet check so the cause can be looked at properly.
