Why Do Dogs Shed? Coat Care Tips for Johns Creek Dogs

If you’ve ever found dog hair on your couch, in your car, and somehow in your coffee, you’ve probably asked yourself: why do dogs shed so much in the first place? The answer isn’t random — it’s actually a well-defined biological process tied to hormones, daylight, and your dog’s individual coat type.

The Dog Shedding Cycle, Explained

Every strand of fur on your dog goes through a cycle with three main phases:

Anagen (growth phase): The hair follicle is actively producing new hair. How long this phase lasts depends on the breed — some dogs have a short anagen phase, which is why their coat never grows very long, while others (like many long-haired breeds) have a much longer growth phase.

Catagen (transition phase): Growth slows and the follicle begins to shrink. This is a short, transitional stage.

Telogen (resting phase): The hair is fully formed but no longer growing. Eventually, it releases and falls out, making room for a new hair to begin the cycle again.

This cycle runs continuously and at different times across different hairs, which is why healthy shedding usually looks like a steady, low-level process rather than one dramatic event — except in dogs with a heavy undercoat, where shedding can happen in more noticeable waves.

Why Does Seasonal Dog Shedding Happen?

Seasonal dog shedding is most noticeable in double-coated breeds — think Huskies, Golden Retrievers, German Shepherds, and Labradors. These dogs have both a soft, insulating undercoat and a coarser topcoat. As daylight hours change, it signals the body to adjust: shedding the heavier winter undercoat in spring to prepare for warmer weather, and shedding lighter fur in fall to grow in a denser coat for winter.

This is largely driven by photoperiod (the amount of daylight) rather than temperature alone, which is why indoor dogs exposed to consistent artificial lighting sometimes shed more evenly year-round instead of in two big seasonal bursts.

For dog owners in Johns Creek and Alpharetta, GA, this seasonal shift is easy to notice — the region’s hot, humid summers and mild winters mean double-coated breeds often go through a heavier “coat blow” in spring as they shed out their winter undercoat to stay cool through Georgia’s long, warm season.

Is Dog Hair Loss Normal?

Some level of shedding is completely normal for nearly every breed — even so-called “hypoallergenic” or low-shedding breeds still lose some hair, just at a much slower rate. Generally, dog hair loss is considered normal when:

It happens gradually and evenly across the body

The skin underneath looks healthy, without redness, scabs, or bald patches

Your dog isn’t excessively scratching, licking, or chewing at the area

Shedding is heavier during known seasonal transitions (spring and fall) but calms down afterward

When Shedding Might Signal Something More

While shedding itself is usually harmless, it’s worth paying attention if you notice:

Sudden, patchy hair loss rather than gradual thinning

Bald spots with visible skin irritation, redness, or scabbing

Excessive scratching or chewing paired with the hair loss

Shedding that seems unusually heavy and doesn’t taper off after a few weeks

These patterns can sometimes point to stress, allergies, nutritional gaps, or an underlying skin condition, and are worth mentioning to a veterinarian if they persist.

Shedding is simply your dog’s coat renewing itself — a natural cycle shaped by biology, daylight, and breed. Understanding the dog shedding cycle can help you tell the difference between normal, healthy shedding and the kind of hair loss that’s worth keeping an eye on — especially for dogs adjusting to Georgia’s distinct seasonal shifts in Johns Creek, Alpharetta, and the surrounding areas.
