Understanding Double Coats: Why Deshedding Matters
Every year, usually right around the time you think your house is finally clean, your dog decides to explode.
Fur appears everywhere.
It's on the couch, in the car, on your clothes, floating through the air, and somehow woven into meals you were fairly certain contained no dog hair.
If this sounds familiar, your dog may be blowing coat.
As dramatic as it looks, coat blowing is actually a normal and healthy part of life for many dogs. Understanding what's happening can help you make better grooming decisions and keep your dog more comfortable during heavy shedding seasons.
What Does "Blowing Coat" Mean?
Many breeds have what is called a double coat.
A double coat is made up of two separate layers that work together to protect your dog.
The outer layer consists of guard hairs. These are the longer, coarser hairs you see when you look at your dog's coat. Guard hairs help protect the skin from sun exposure, moisture, dirt, and everyday wear and tear.
Beneath that layer sits the undercoat. The undercoat is softer, denser, and acts as insulation. It helps dogs regulate their body temperature in both hot and cold weather.
When seasons change, many double-coated dogs begin releasing large amounts of that undercoat. This natural process is what groomers refer to as "blowing coat."
While many dogs experience heavier sheds during spring and fall, modern indoor living can change the pattern. Because most dogs spend their lives in climate-controlled homes with artificial lighting, some shed moderately throughout the year instead of following a strict seasonal schedule.
Which Dogs Have Double Coats?
Some double-coated breeds are obvious. Huskies, German Shepherds, Pomeranians, and Australian Shepherds wear their fluff proudly.
Others surprise people.
Labrador Retrievers, Corgis, Shiba Inus, Border Collies, Golden Retrievers, and many mixed breeds also have double coats. Even dogs with relatively short hair can produce astonishing amounts of undercoat.
As many Labrador owners eventually discover, short hair does not always mean less shedding.
Why Does Loose Undercoat Matter?
A lot of people think deshedding is mainly about reducing the amount of fur in the house.
That's certainly a nice bonus.
The bigger reason is comfort.
When loose undercoat becomes trapped in the coat, it can create dense, packed areas that prevent proper airflow to the skin. The coat may start feeling heavy, thick, and difficult to brush through. In some dogs, trapped undercoat can contribute to tangles, hot spots, moisture retention, and skin irritation.
Think of it like wearing a winter coat filled with loose stuffing that never falls out. Eventually it becomes bulky, uncomfortable, and difficult to manage.
Removing loose undercoat helps the coat function the way nature intended.
What Is a Deshed Treatment?
A professional deshed treatment is designed to remove coat that is already loose and ready to come out.
The goal is not to strip the coat.
The goal is to help the natural shedding process along.
A proper deshed appointment typically includes specialized bathing, conditioning, high-velocity drying, and thorough brushing techniques that help release undercoat while preserving the healthy coat that should remain.
Many owners are amazed by the amount of fur that comes out during the process.
Dogs often seem amazed too.
I've seen dogs walk out after a deshed looking lighter, moving more freely, and acting as though they just left a spa carrying significantly less baggage.
Why Not Just Shave It Off?
This is one of the biggest misconceptions surrounding double-coated breeds.
When people see all that fur, especially during summer, shaving can seem like the obvious solution.
The reality is that a healthy double coat serves an important purpose.
That coat helps regulate temperature, protects the skin from UV exposure, provides insulation from heat and cold, and acts as a barrier against environmental irritants.
When a double coat is shaved, the undercoat and guard hairs don't always grow back evenly. In some dogs, the texture changes permanently. Others may develop patchy regrowth, coat damage, or areas that remain thin for months or even years.
A shaved double coat is not automatically ruined forever, but it does carry risks that many owners don't realize.
In most cases, regular brushing and professional deshedding provide the benefits people are looking for without sacrificing the coat's natural function.
How Do You Know Your Dog Needs a Deshed?
Your dog might benefit from a deshed treatment if:
Fur comes out in handfuls when you pet them
The coat feels unusually dense or packed
You notice thick areas around the hips, neck, or rear
Brushing seems less effective than usual
Your vacuum cleaner has started filing workplace complaints
Heavy shedding is normal.
Living inside a walking fur cloud doesn't have to be.
The Bottom Line
Your dog's coat is doing a remarkable amount of work every single day.
It protects their skin, helps regulate body temperature, and serves as one of the body's natural defense systems. When we support that coat through proper brushing, routine grooming, and professional deshedding, we're not just reducing the amount of fur on our furniture.
We're helping the coat stay healthy and functional.
Because grooming isn't about fighting the fur.
It's about understanding why it's there in the first place.
