My Dog’s Hair is Falling Out: What Do I Do?

Seeing your dog’s hair fall out can be concerning. While some shedding is normal, unusual hair loss could be linked to allergies, parasites, infections, or even hormonal imbalances.

Why Is My Dog Losing Hair?

Several factors can contribute to hair loss in dogs. Some are minor, while others require veterinary attention.

Allergies and Sensitivities

Allergies are one of the most common reasons a dog’s hair is falling out. Reactions can stem from food, environmental triggers (like pollen or dust mites), or contact allergens such as shampoos or fabrics. Dogs with allergies often exhibit additional symptoms like itching, red skin, or ear infections. If you notice these signs along with hair loss, your veterinarian can help determine the cause and recommend appropriate solutions.

Parasites That Cause Hair Loss

External parasites such as fleas, mites, and ticks can lead to hair loss. Flea allergies, in particular, cause intense itching and excessive scratching, resulting in bald spots. Mites, responsible for mange, burrow into the skin and trigger severe irritation, leading to patchy hair loss. Regular parasite prevention is key to protecting your dog’s coat and overall health.

Fungal or Bacterial Infections

Skin infections can lead to significant hair loss. Ringworm, a fungal infection, creates circular bald patches and is highly contagious. Bacterial infections often develop from excessive licking or scratching and may cause inflamed skin, sores, and foul odors. If your dog’s hair is falling out in localized areas or if the skin appears irritated, a veterinary exam can help diagnose and treat the condition effectively.

Hormonal Imbalances and Hair Loss

A dog’s endocrine system plays a role in coat health. When hormone levels become unbalanced, hair loss can occur.

Hypothyroidism

Hypothyroidism happens when the thyroid gland produces insufficient hormones. This condition can cause thinning fur, lethargy, weight gain, and skin infections. While common in middle-aged and older dogs, it requires veterinary diagnosis and management.

Cushing’s Disease

Cushing’s disease results from excess cortisol production and can lead to hair loss, increased thirst, a pot-bellied appearance, and skin issues. Dogs with this condition may lose fur in symmetrical patterns along their body. If your pet exhibits these symptoms, a veterinarian can perform diagnostic tests to confirm and treat the condition.

Stress and Anxiety-Related Hair Loss

Dogs experience stress just like humans, and chronic anxiety can manifest as excessive licking, chewing, or scratching. Separation anxiety, changes in routine, or new environments can contribute to hair loss. Dogs who groom themselves excessively due to stress may develop bald spots, particularly on their legs and paws. Addressing anxiety through behavioral support and environmental enrichment can help reduce stress-related hair loss.

When to See a Veterinarian

Not all hair loss is cause for alarm, but certain signs indicate a need for veterinary care. If your dog’s hair is falling out in large clumps, accompanied by redness, scabs, or behavioral changes, it’s time for a professional evaluation. Sudden or widespread hair loss can point to underlying health concerns that require treatment. The team at North Kenny Veterinary Hospital can help.
