Why Is My Alaskan Malamute Losing Patches of Fur? Causes

Updated: July 14, 2026 By Jhon Oblak 9 min read

Noticing bare spots on your dog can trigger immediate worry. This guide explains why an Alaskan Malamute losing patches of fur needs attention.

Simply put, an Alaskan Malamute losing patches of fur is not normal shedding. It often points to skin disease, hormone imbalance, or nutritional deficiency. You should schedule a vet exam to find the cause early.

Key Takeaways

  • An Alaskan Malamute losing patches of fur shows bare skin instead of even seasonal shedding.
  • Hypothyroidism causes symmetrical alopecia in roughly 1 out of 200 dogs according to veterinary data.
  • Zinc-responsive dermatosis frequently affects Malamutes and creates crusty bald areas on the face.
  • Skin problems account for about 25% of all veterinary visits based on current AVMA reporting.
  • A veterinarian must run skin scrapes and blood tests to confirm the true root cause.

An Alaskan Malamute losing patches of fur shows bare skin spots instead of even shedding. This condition is called alopecia when hair falls out abnormally. Malamutes normally shed heavily, but round bald spots are not normal.

Important: Patchy fur loss differs from seasonal blowout. A vet should check any odd bald area on your dog.

The Alaskan Malamute is a northern breed with a dense double coat. Their undercoat protects them from cold. When they lose patches, the guard hairs and undercoat both thin out in specific areas.

Several body systems control hair growth. Hormones, nutrients, and skin health all play a role. A breakdown in any system can cause localized or widespread baldness.

How the Hair Cycle Works

Dog hair grows in three phases. The active phase builds the strand. The resting phase holds it. The release phase sheds it naturally.

  • The anagen phase lasts months in Malamutes and creates long guard hairs.
  • The telogen phase keeps the coat stable through winter cold.
  • The exogen phase releases old hair during the spring blowout.
  • Disease can stall the cycle and stop new hair from replacing old.

Common Body Areas Affected

  • The flanks show hormone related loss on both sides evenly.
  • The face and ears show zinc deficiency crusts and bare edges.
  • The lower back shows flea allergy chewing and thin fur.
  • The legs show mange spots on young dogs first.

How Does Shedding Differ from Patchy Loss?

Malamutes shed their undercoat twice a year in a process called blowing coat. This looks like massive tufts of fur everywhere. It does not create smooth bald skin.

Patchy loss creates distinct areas where hair is gone. You can see skin clearly. The border may be sharp or creeping. Shedding never exposes skin unless you shave the dog.

Tip: Run your hands over your dog weekly. Feel for thin spots before they become visible bald patches.

Signs of Normal Shedding

  • Loosing soft undercoat fluff in large amounts.
  • Coat looks thinner overall but skin stays covered.
  • No redness, odor, or itching during the process.
  • Shedding lasts two to four weeks then stops.

Signs of Abnormal Patches

  • Bare pink or black skin with zero hair follicles visible.
  • Dog scratches, licks, or bites the area often.
  • Scale, crust, or moisture appears on the bald spot.
  • Hair falls out in quarter sized or larger circles.

According to the American Veterinary Medical Association, skin problems account for about 25% of all veterinary visits. Many of those cases involve alopecia in breeds like the Malamute.

Seasonal Timeline

  1. Winter builds a thick undercoat for warmth.
  2. Early spring triggers the first blowout of soft fur.
  3. Late fall triggers a smaller second shed before cold.
  4. Any bald spot outside these windows needs review.

What Are the Main Causes of Patchy Fur Loss?

Multiple medical issues create an Alaskan Malamute losing patches of fur. We group them into parasites, allergies, hormones, infection, and nutrition. Each has a different fix.

Parasites and Insects

Fleas, mites, and ticks irritate the skin. The dog scratches and pulls hair out. Demodectic mange causes oval bald spots on young dogs.

  • Flea allergy dermatitis makes the dog chew hindquarters raw.
  • Sarcoptic mange spreads fast and causes intense itch and loss.
  • Tick bites can trigger localized infection and fur drop.

Allergies and Atopy

Canine atopic dermatitis is a common allergy. The dog reacts to pollen, dust, or food. Constant rubbing removes hair in patches.

According to a Wikipedia summary of canine atopic dermatitis, up to 15% of dogs suffer from environmental allergies that trigger patchy hair loss.

Food allergies also cause ear inflammation and flank licking. The dog loses fur from repeated moisture and chew. A strict elimination diet finds the trigger.

Hormonal Imbalances

Hypothyroidism slows metabolism and halts hair growth. Cushing’s disease overloads the body with cortisol. Both create symmetrical bald patterns.

According to the Merck Veterinary Manual, hypothyroidism affects roughly 1 in 200 dogs and causes symmetrical alopecia.

  • The thyroid gland fails to make enough T4 hormone.
  • The adrenal gland makes too much cortisol in Cushing’s.
  • Both conditions need blood tests for clear proof.
  • Medicine can restore coat within months of starting.

Nutritional Deficiencies

Zinc-responsive dermatosis hits Malamutes hard. The breed cannot absorb zinc well. Lack of zinc causes crusty edges and fur loss around eyes and mouth.

According to the American Kennel Club, Alaskan Malamutes are among the breeds prone to zinc-responsive dermatosis, which leads to crusty patches and fur loss.

Omega-3 fatty acids also support skin seal. Low levels make the coat dull and thin. Quality fish oil supplements help repair the barrier.

Fungal and Bacterial Infection

  • Ringworm creates circular scaly bald spots on the body.
  • Staph infection follows a scratch and oozes then defuzes area.
  • Yeast overgrowth turns skin greasy and smells bad.

Autoimmune and Stress Causes

Rare immune disease attacks hair follicles directly. Stress lick granuloma creates a bare sore on the leg. Both need behavior or immune care.

Cause Typical Patch Location Key Signal Vet Test
Flea Allergy Lower back, tail base Intense scratching Visual flea check
Hypothyroidism Trunk, both sides even Lethargy, weight gain Blood TSH test
Zinc Deficiency Face, ears, joints Crusty lesions Diet review
Ringworm Anywhere, round Scaly red ring UV light exam
Mange Ears, elbows, chest Severe itch, redness Skin scrape

Who Should Worry About This Condition?

Any owner seeing bare skin should act. Puppies with patches may have mange or fungus. Adult dogs with slow loss may have hormone issues.

High Risk Groups

  • Malamutes under two years may inherit zinc malabsorption.
  • Dogs eating low quality grain heavy food lack nutrients.
  • Households with multiple pets spread parasites quickly.
  • Region with high pollen raises atopy risk in spring.

Warning: If your dog’s patch spreads in days or smells bad, treat it as urgent. Infection can enter the blood.

How to Get a Diagnosis

Your veterinarian follows clear steps to find why your Alaskan Malamute losing patches of fur is happening. The process is simple but thorough.

  1. Show the vet the exact spots and note when you first saw them.
  2. The vet performs a skin scrape to check for mites under microscope.
  3. A blood panel checks thyroid and adrenal hormone levels.
  4. Fungal culture or UV lamp rules out ringworm quickly.
  5. Food trial may follow if allergy looks like the root cause.

What the Vet Needs from You

  • Your dog’s current food brand and feeding amount.
  • List of shampoos, flea products, or supplements used.
  • Timeline of shedding versus patch growth.
  • Any changes in water, yard, or new pets at home.

How to Treat Each Cause

Treatment depends on the confirmed diagnosis. We list the main paths your vet may take. Follow the plan strictly for best regrowth.

Parasite Treatment

  1. Apply vet approved flea control to all pets in the home.
  2. Give oral or topical mite medicine for mange cases.
  3. Wash bedding in hot water to kill eggs and larvae.

Hormone Therapy

  • Thyroid pills restore T4 levels within four to six weeks.
  • Cushing’s medicine lowers cortisol production slowly.
  • Retest blood every three months to tune the dose.

Nutrition Fix

  • Add zinc supplement at vet directed milligram strength.
  • Switch to a meat first diet with no filler grains.
  • Include fish oil with EPA and DHA for skin repair.

Infection Care

  1. Ringworm needs oral antifungal and medicated bath.
  2. Staph infection needs antibiotic course of two weeks.
  3. Yeast needs topical mousse and dry environment.

Home Care and Prevention

Good home habits lower the chance of repeat patches. You can build a simple routine with the items below.

  • Brush your Malamute twice a week to spread skin oils.
  • Bathe every six weeks with a gentle oatmeal shampoo.
  • Vacuum dog areas daily during high shed seasons.
  • Store food in sealed bins to keep nutrients fresh.
  • Check the coat after hikes for ticks and burrs.

Tip: Keep a phone album of your dog’s coat. Compare monthly photos to catch slow thinning early.

When to Seek Emergency Care

Most patches are not life threatening. Some signs mean you must go to the clinic the same day. Watch for the red flags below.

  • The bare spot bleeds or oozes yellow fluid.
  • Your dog develops a fever or stops eating.
  • Swelling spreads past the original patch edge.
  • Breathing changes after a suspected allergic reaction.

Common Myths vs Facts

Many false ideas surround Malamute coat problems. We clear up three common ones.

Myth 1: Shaving Helps the Fur Grow Back

Fact: Shaving a double coated breed damages guard hairs. It does not treat the disease causing loss. The coat may return uneven.

Myth 2: Patchy Loss Is Just Heavy Shedding

Fact: Shedding never leaves skin bare. Patches signal infection, allergy, or hormone failure that needs medicine.

Myth 3: Home Remedies Cure Bald Spots

Fact: Coconut oil or oatmeal baths soothe skin but cannot fix hypothyroidism. Only a vet prescription corrects the root cause.

Frequently Asked Questions

Will the fur grow back after treatment?

In most cases, hair returns within six to ten weeks once the cause is fixed. Scarring from deep infection may leave permanent thin areas. Early vet care gives the best regrowth.

Can I prevent patchy loss in my Malamute?

Feed a balanced diet with zinc and Omega-3 fatty acids. Use monthly flea control. Bathe with mild dog shampoo. These steps lower risk significantly.

Is losing patches contagious to humans?

Ringworm and mange can pass to people through touch. Wash hands after contact. Keep children away from active lesions until vet clears the dog.

How much does diagnosis cost currently?

A basic skin scrape and exam runs about 50 to 100 dollars. Blood work adds 150 to 250 dollars. Fungal culture costs roughly 30 to 60 dollars.

Should I change food if I see a bald spot?

Do not switch food blindly. Record the patch and see a vet first. Food allergy needs a controlled elimination diet under professional guidance.

Final Thoughts

An Alaskan Malamute losing patches of fur needs prompt vet attention rather than wait and see. Causes range from fleas to thyroid disease, but most are treatable. Use the checklists above to track symptoms and act early.
