Every dog sheds — but when the fur coming off your dog suddenly increases, or when shedding is accompanied by other changes, it is natural to wonder whether something is wrong. Most of the time, increased shedding has a simple explanation: the season changed, the heat came on, or your dog is blowing coat. But shedding can also be one of the first visible signs of a health issue. Here is how to tell the difference.
Normal Reasons Dogs Shed More
- Seasonal coat blows. Spring and fall bring the heaviest shedding as dogs swap their undercoat. This is normal, temporary, and usually lasts two to four weeks.
- Indoor heating. Canadian winters mean months of dry, heated indoor air, which dries out skin and increases shedding. Dogs that live primarily indoors often shed steadily all winter.
- Daylight changes. Shedding is triggered more by daylight than temperature, so indoor dogs under artificial light may shed on their own schedule.
- Life stage. Puppies shed their soft puppy coat as the adult coat comes in, and senior dogs sometimes shed more as their coat changes with age.
- Stress. A move, a new pet, loud construction, or a change in routine can cause a temporary increase in shedding. This usually resolves once the dog settles.
- Recent bathing or grooming changes. A new shampoo, over-bathing, or a lapse in brushing can all change how much loose fur you notice.
When Shedding May Signal a Health Issue
Shedding alone is rarely a concern — it is shedding plus other symptoms that warrants attention. Contact your veterinarian if increased shedding comes with any of the following:
- Bald patches or noticeably thinning areas of coat
- Red, flaky, or irritated skin
- Constant scratching, licking, or chewing at the skin
- Sores, scabs, or a yeasty or unusual odour from the skin
- Changes in appetite, energy, thirst, or behaviour alongside the shedding
These combinations can be associated with allergies, skin infections, parasites such as mites, hormonal conditions like hypothyroidism, or nutritional deficiencies — all of which need professional diagnosis. Only a veterinarian examining your dog can determine the cause.

What You Can Do at Home
For normal, healthy shedding — even heavy seasonal shedding — the answer is consistent grooming, not worry. Brush regularly with a proper deshedding tool: the Furbliss One-Click Deshedding Brush removes loose undercoat efficiently so it does not end up on your floors, and regular sessions let you monitor your dog's skin and coat condition up close. Feed a complete, balanced diet appropriate for your dog's life stage, since nutrition is the foundation of a healthy coat. And keep a simple mental log: when the heavy shedding started, whether the skin looks normal, and whether anything else changed. That timeline is genuinely useful information for your vet if you do end up booking a visit.
Do Not Try to Diagnose at Home
It is tempting to search symptoms online and conclude your dog has a specific condition — but skin and coat issues look remarkably similar across very different causes. Allergies, mites, fungal infections, and hormonal disorders can all present as increased shedding with itching. Treating the wrong cause wastes time and can make things worse. If the shedding pattern worries you, a vet visit with a skin examination is the fastest path to an answer.
Key Takeaways
- Seasonal changes, indoor heating, stress, and life stage are the most common reasons for increased shedding.
- Shedding plus bald patches, irritated skin, or behaviour changes warrants a vet visit.
- Regular deshedding keeps normal shedding manageable and helps you spot problems early.
- Do not diagnose skin conditions at home — many look alike but need different treatment.
Frequently Asked Questions
Is it normal for my dog to shed more in winter indoors?
Yes. Dry heated air dries out skin and coat, increasing shedding through the winter months. Regular brushing and making sure your dog stays hydrated help.
Can stress really cause shedding?
Yes — dogs can shed more during stressful periods, sometimes called "stress shedding." It is usually temporary and resolves as the dog adjusts.
How quickly should I see a vet about excessive shedding?
If shedding is the only symptom and your dog seems otherwise healthy, monitor for a week or two while brushing regularly. If you notice bald spots, skin changes, itching, or behaviour changes, book a vet visit promptly.
