Dog Hair Loss Treatment

Posted by Michael Musch on

Hair loss in dogs, or shedding, is a natural physiological process that can occur throughout the year, although the most intense periods usually occur in spring and autumn. This phenomenon, influenced by hormonal, environmental and genetic factors, raises many questions: what are the exact causes? Are there effective solutions to limit its extent? Does regular brushing play a determining role? How often should it be done to maintain the health of the coat? Are certain breeds less prone to hair loss?

Abnormal Causes of Hair Loss

Shedding is a normal physiological process in dogs. However, excessive or localized hair loss should be given special attention and warrants veterinary consultation. Alopecia, defined as abnormal hair loss, may be a symptom of an underlying dysfunction affecting the animal's health. It may manifest itself locally on certain body regions or extend to the entire coat.

Different etiologies can be at the origin of this anomaly, whether they are pathological, environmental or nutritional. Common causes include dermatological conditions (allergic dermatitis, bacterial or fungal infections), hormonal imbalances (hypothyroidism, hypercorticism), as well as certain nutritional deficiencies. Similarly, parasitic factors (infestation by fleas, mites or fungi) and psychogenic disorders (stress, anxiety) can contribute to abnormal hair loss.

Presence of Parasites and Abnormal Hair Loss

Flea Infestation and Allergic Dermatitis

Excessive hair loss, accompanied by intense itching and compulsive licking, may indicate a parasitic infestation. Fleas, responsible for flea allergic dermatitis (FAD), cause localized scratching lesions (hindquarters, base of the tail, inner thighs, neck). Irritation leads to exacerbated itching, promoting alopecia and skin superinfections.

A careful examination of the coat can identify the presence of flea droppings. The use of a specific comb facilitates this detection. Rigorous antiparasitic treatment is essential: regular application of a suitable antiparasitic prevents infestation and its complications. Disinfection of the environment is also required to eradicate eggs and larvae, thus limiting any risk of recurrence.

Dermatological Conditions and Hair Loss

Caused by the fungus Microsporum canis , ringworm causes localized alopecia in the form of circular scaly patches. Generally non-itchy, it may be accompanied by scratching in the event of superinfection. Highly contagious, it requires rapid antifungal treatment.

Demodicosis ( Demodex canis ) and sarcoptic mange ( Sarcoptes scabiei ) cause hair loss associated with skin inflammation. Leishmaniasis ( Leishmania infantum ), a vector-borne disease transmitted by sandflies, causes progressive alopecia and severe skin lesions.

A veterinary diagnosis is essential for appropriate care.

Excessive hair loss can result from a deficiency in essential nutrients ( minerals, vitamins, trace elements, essential fatty acids ) that are essential for the health and growth of the coat.

A zinc deficiency , especially in Nordic breeds such as the Husky, impairs the quality of the coat. A deficiency in keratin and biotin , major components of the hair, results in a dull coat, brittle hair and excessive shedding.

A balanced and suitable diet is essential to prevent these disorders and maintain the integrity of the coat.

Testicular or ovarian tumors , hypothyroidism , diabetes mellitus , and Cushing's syndrome alter the hair growth cycle, resulting in localized alopecia, often associated with hyperpigmentation of the affected areas.

Atopy , allergies (mites, pollen, food, contact) and pyoderma cause excessive hair loss, accompanied by skin erythema and intense pruritus , promoting superinfections.

Stress , particularly related to a change of environment, can induce compulsive licking , responsible for localized alopecia, mainly on the front legs and at the base of the tail .

A veterinary diagnosis is essential to identify the underlying cause and initiate appropriate treatment.

When Do Dogs Shed?

The shedding cycle in dogs follows a biannual rhythm, mainly influenced by seasonal changes:

  • Spring : abundant loss of the winter coat, denser, replaced by finer hair adapted to high temperatures.
  • Autumn : loss of summer hair and growth of a thicker coat to face the cold.

Telogen phase (spring) : shedding of dead hairs, marking the end of the hair cycle.

Anagen phase (winter) : growth of the new coat, ensuring optimal thermal protection.

  • Dogs living indoors are less affected by climatic variations.
  • Their hair loss is often more diffuse and regular throughout the year, without marked seasonal peaks.

Proper management of brushing and coat maintenance is essential to support these shedding phases and preserve the dog's skin health.

HOW TO LIMIT HAIR LOSS

Coat Prevention and Maintenance

Regular Bathing and Brushing

Frequent brushing stimulates blood circulation and promotes hair regrowth.

Bathing with a suitable shampoo helps to remove dead hair and maintain healthy skin.

Antiparasitic Treatments All Year Round

Regular application of external antiparasitics prevents flea infestations and reduces hair loss due to itching.

Quarterly deworming limits nutritional deficiencies caused by intestinal parasites.

High Quality Power Supply

A balanced nutrition enriched with Omega-3 and Omega-6 improves the resistance and shine of the coat.

High-quality foods prevent deficiencies that cause excessive hair loss.

Food Supplements and Hair Health

  • Supplements rich in Omega-3, Omega-6, brewer's yeast and B vitamins strengthen the hair follicle.
  • Although they do not prevent seasonal shedding, they reduce excessive shedding and improve coat quality.

Regular maintenance and appropriate nutritional support are essential to maintain a healthy coat and limit hair loss.
