What could be wrong if a dog starts shedding excessively? - in detail

Excessive shedding in dogs, also known as alopecia, can indicate various underlying issues. Here are some possible causes and associated symptoms:

  1. Parasites: Flea or tick infestations can cause excessive hair loss due to allergic reactions or irritation. Check your dog's skin for signs of parasites, such as red bumps, scabs, or flea dirt (small black specks).

  2. Allergies: Food allergies or environmental allergens like pollen, dust mites, or mold can trigger excessive shedding. Allergic reactions often cause itching, leading to hair loss. Look for redness, swelling, or hot spots on your dog's skin.

  3. Hormonal Imbalances: Hypothyroidism (underactive thyroid) and Cushing's disease (overactive adrenal glands) are common hormonal disorders that can cause hair loss in dogs. Other symptoms may include lethargy, weight gain or loss, increased thirst or urination, and changes in appetite.

  4. Infections: Bacterial or fungal skin infections can result in excessive shedding. Look for redness, inflammation, crusts, or an unpleasant odor. Ringworm, a fungal infection, often appears as circular bald patches with broken hair at the edge.

  5. Autoimmune Disorders: Some autoimmune diseases, such as lupus or pemphigus, can cause the immune system to attack the skin and hair follicles, leading to hair loss. Symptoms may include lesions, crusts, or scabs on the skin.

  6. Stress or Anxiety: Prolonged stress or anxiety can lead to excessive shedding in some dogs. Other signs of stress might include changes in appetite, sleep patterns, or behavior.

  7. Poor Nutrition: A diet lacking in essential nutrients, such as omega-3 and omega-6 fatty acids, proteins, and vitamins, can contribute to excessive shedding. Look for dull, dry coat, dandruff, or poor skin condition.

  8. Age or Breed: Some breeds are prone to hair loss due to genetics, while senior dogs may experience age-related thinning of the coat.

If your dog is shedding excessively, it's crucial to consult a veterinarian for a proper diagnosis and treatment plan. The vet will likely perform a physical examination, skin scrapings, or blood tests to determine the underlying cause.
