Why Your Dog is Shedding More This Fall (And What to Do About It)

If you've noticed tumbleweeds of fur rolling across your floors and your dog leaving a trail of hair everywhere they go, you're not imagining things. Fall shedding is a real phenomenon, and it can be surprisingly intense. While some shedding is normal year-round, many dogs experience a dramatic increase in hair loss during autumn months.

Understanding why this happens and how to manage it can help you keep your home cleaner, your dog more comfortable, and prevent potential health issues related to excessive shedding. Let's explore the science behind fall shedding and the best strategies for dealing with all that extra fur.

The Science of Seasonal Shedding

Shedding is a natural, healthy process that allows dogs to replace old or damaged hair with new growth. Seasonal shedding is triggered by changes in daylight hours and temperature, not just temperature alone.

Why Dogs Shed More in Fall

As days grow shorter and temperatures drop, your dog's body receives signals to prepare for winter. This triggers a coat change—shedding the lighter summer coat to make way for a thicker, warmer winter coat.

The biological process:

• Photoperiod response: Decreasing daylight hours trigger hormonal changes that affect hair growth cycles

• Temperature regulation: Dogs grow denser undercoats for insulation against cold weather

• Coat replacement: Old, damaged summer fur is shed to make room for new winter growth

• Natural cycle: Hair follicles go through growth, rest, and shedding phases synchronized with seasons

Double-Coated vs. Single-Coated Breeds

The intensity of fall shedding varies significantly based on coat type.

Double-coated breeds (most dramatic shedding):

• German Shepherds

• Huskies and Malamutes

• Golden Retrievers and Labrador Retrievers

• Border Collies and Australian Shepherds

• Pomeranians and Corgis

• Bernese Mountain Dogs and Great Pyrenees

These breeds have a soft, dense undercoat beneath a coarser outer coat. They typically "blow" their coat twice a year—spring and fall—shedding massive amounts of undercoat.

Single-coated breeds (moderate, consistent shedding):

• Poodles and Doodle mixes

• Maltese and Yorkshire Terriers

• Greyhounds and Whippets

• Boxers and Pit Bulls

These dogs shed more consistently throughout the year with less dramatic seasonal variation.

Low-shedding or non-shedding breeds:

• Poodles (all sizes)

• Bichon Frises

• Portuguese Water Dogs

• Some Terrier breeds

These breeds have hair that grows continuously rather than going through distinct shedding cycles. They require regular grooming and haircuts but shed minimally.

Is This Normal or Excessive Shedding?

While fall shedding is normal, it's important to distinguish between seasonal coat changes and problematic hair loss.

Normal Seasonal Shedding

• Increased hair loss that begins in late summer/early fall

• Lasts 2-4 weeks (sometimes up to 6-8 weeks for heavy shedders)

• Skin underneath looks healthy—no redness, flaking, or irritation

• Hair comes out in clumps or large amounts when brushed

• Dog's behavior, appetite, and energy remain normal

• New coat growth is visible underneath

Abnormal Shedding (Requires Veterinary Attention)

• Bald patches or thinning areas

• Red, inflamed, or irritated skin

• Excessive itching, scratching, or licking

• Scabs, sores, or hot spots

• Foul odor from skin or coat

• Brittle, dry, or dull coat

• Sudden, dramatic hair loss outside of typical shedding seasons

• Behavioral changes, lethargy, or appetite loss

Health Conditions That Cause Excessive Shedding

If shedding seems abnormal, several health issues could be the cause.

Common Medical Causes

• Allergies: Environmental or food allergies cause inflammation and hair loss

• Parasites: Fleas, mites, or lice damage skin and coat

• Hormonal imbalances: Thyroid problems, Cushing's disease, or other endocrine disorders

• Nutritional deficiencies: Poor diet lacking essential fatty acids, proteins, or vitamins

• Skin infections: Bacterial or fungal infections (ringworm, yeast)

• Stress or anxiety: Can trigger excessive shedding and over-grooming

• Medications: Some drugs have shedding as a side effect

If you suspect a medical issue, consult your veterinarian for proper diagnosis and treatment.

Managing Fall Shedding: The Essential Toolkit

While you can't stop seasonal shedding, you can manage it effectively with the right tools and techniques.

1. Brushing: Your First Line of Defense

Regular brushing is the single most effective way to manage shedding.

Brushing frequency during fall shedding:

• Double-coated breeds: Daily, or even twice daily during peak shedding

• Single-coated breeds: 3-4 times per week

• Short-haired breeds: 2-3 times per week

Benefits of regular brushing:

• Removes loose fur before it ends up on your furniture

• Distributes natural oils for a healthier coat

• Stimulates blood circulation to the skin

• Allows you to check for skin issues, lumps, or parasites

• Reduces matting and tangles

• Bonding time with your dog

2. Choosing the Right Grooming Tools

Different coat types require different tools.

For double-coated breeds:

• Undercoat rake: Penetrates to remove loose undercoat without cutting

• Slicker brush: Removes loose hair and prevents matting

• De-shedding tool (FURminator-style): Removes massive amounts of undercoat (use carefully to avoid over-brushing)

• Pin brush: For finishing and fluffing the outer coat

For short-haired breeds:

• Rubber curry brush: Loosens and removes dead hair

• Bristle brush: Distributes oils and adds shine

• Grooming glove: Convenient for quick daily brushing

For long, single-coated breeds:

• Slicker brush: Prevents tangles and removes loose hair

• Metal comb: Works through mats and checks for tangles

• Pin brush: Gentle daily brushing

3. Bathing During Shedding Season

Strategic bathing can help loosen and remove dead hair.

Bathing tips for shedding season:

• Frequency: Every 2-4 weeks during heavy shedding (don't over-bathe, which can dry skin)

• Brush first: Always brush thoroughly before bathing to remove loose hair and prevent matting

• Use quality shampoo: Choose moisturizing, dog-specific formulas; consider de-shedding shampoos

• Thorough rinsing: Leftover shampoo can cause skin irritation and more shedding

• Blow-dry: Use a pet-safe dryer on low heat while brushing to remove even more loose hair

• Post-bath brushing: Brush again after drying to remove hair loosened by bathing

4. Professional Grooming

For heavy shedders, professional grooming can be a game-changer.

Professional de-shedding treatments include:

• Specialized shampoos and conditioners

• High-velocity dryers that blow out loose undercoat

• Professional-grade de-shedding tools

• Expert technique to remove maximum loose hair

Many dogs benefit from professional grooming at the beginning of fall shedding season, followed by regular home maintenance.

Nutrition's Role in Coat Health

What your dog eats directly affects coat quality and shedding.

Essential Nutrients for Healthy Coats

• Omega-3 and Omega-6 fatty acids: Support skin health and reduce inflammation

• High-quality protein: Hair is made of protein; adequate amounts support healthy growth

• Biotin and B vitamins: Essential for skin and coat health

• Zinc and copper: Support hair follicle function

• Vitamin E: Antioxidant that supports skin health

Dietary Strategies

• Feed high-quality dog food: Look for named meat proteins as first ingredients

• Consider fish oil supplements: Rich in omega-3s (consult your vet for dosage)

• Add fresh, whole foods: Small amounts of salmon, sardines, or eggs (cooked)

• Ensure adequate hydration: Dehydration affects skin and coat health

• Avoid frequent diet changes: Consistency supports coat health

Managing Fur in Your Home

Even with excellent grooming, some fur will end up in your house. Here's how to manage it.

Cleaning Strategies

• Vacuum frequently: Daily during peak shedding; use pet hair attachments

• Invest in a quality vacuum: Models designed for pet hair make a huge difference

• Lint rollers and pet hair removers: Keep them in every room and your car

• Rubber gloves: Dampen and rub over furniture to collect hair

• Microfiber cloths: Attract and hold pet hair better than regular cloths

• Washable furniture covers: Protect couches and beds; wash weekly

• Air purifiers with HEPA filters: Reduce airborne dander and hair

Prevention Tactics

• Designate pet-free zones: Keep bedrooms or specific furniture off-limits

• Provide pet beds: Encourage your dog to use their own bed

• Brush outdoors: Keeps loose hair outside

• Use doormats: Wipe paws to reduce tracked-in fur

What NOT to Do

Some common practices can actually make shedding worse or harm your dog.

Avoid these mistakes:

• Shaving double-coated breeds: Disrupts natural insulation and can cause permanent coat damage

• Over-bathing: Strips natural oils, leading to dry skin and more shedding

• Using human shampoo: Wrong pH for dog skin; causes irritation

• Aggressive brushing: Can damage skin and coat; use gentle, consistent strokes

• Ignoring the problem: Matted fur can cause skin issues and discomfort

• Feeding low-quality food: Poor nutrition shows in coat quality

When to See a Veterinarian

Consult your vet if you notice:

• Bald patches or significant thinning

• Skin changes (redness, flaking, sores)

• Excessive itching or discomfort

• Sudden, dramatic increase in shedding outside normal seasons

• Dull, brittle, or dry coat despite good care

• Behavioral changes accompanying shedding

These signs may indicate underlying health issues that require professional attention.
