What Causes Excessive Canine Shedding?

It is normal for a dog to shed. This is a seasonal occurrence. However, when excessive shedding occurs, or if shedding occurs when it is not supposed to, there may be cause for concern. Excessive hair loss in dogs is a sign of one of the many health problems. These can be mild or life-threatening. If you notice unusual and/or excessive shedding, consult a vet immediately to get the right diagnosis.



The causes of excessive canine shedding may range from hormonal imbalance to autoimmune diseases to poor nutrition and stress.

  1. Hormonal Imbalance

    • Canine diseases, such as hypothyroidism, diabetes and Cushing's disease, that cause hormonal imbalance can result in excessive shedding. Hormonal imbalance is a serious health problem and can be life-threatening if not treated. Treatment may involve hormone therapy or surgery.

    Cancer

    • Malignant tumors that cause shedding are typically found in the ovaries and testes of dogs. They are associated with hormonal imbalance. Treatment involves surgically removing the affected organ and then giving the pet the correct cancer therapy, such as chemotherapy.

    Autoimmune Diseases

    • If the shedding occurs in patches, it is most probably an autoimmune problem. This is a type of alopecia that affects dogs and tends to disappear on its own. If the shedding persists, treatment may involve ortisone injections.

    Poor Nutrition

    • Unusual shedding also occurs when a dog does not get right amounts of vitamins and minerals through its diet. Feeding the dog a protein-rich diet and giving vitamin and mineral supplements helps to resolve this health issue. Supplements of essential fatty acids help to maintain the skin and coat and reduce shedding.

    Skin Parasites

    • If the dog is infested with demodex mites, mange can occur. This results in hair loss. The loss is typically seen around the eyes but can occur on any part of the body attacked by the mites. Skin scrapings reveal the presence of mites. The vet will prescribe a topical cream or wash to rid the dog of the mites. Fleas are also responsible for causing excessive shedding. Check the dog for fleas and then consult the vet for the right treatment.

    Fungal Infection

    • One of the most common fungal infections to affect dogs is ringworm. This causes loss of fur at the infected site along with itching and skin irritation. Using a medicated topical spray, such as Miconazole, or cream helps to get rid of the infection and stop shedding.

    Stress

    • Relocation, a new addition in the family or being left alone for long hours can lead to stress in dogs, which results in sudden loss of fur. However, if the cause of stress is removed, excessive shedding will usually stop.

    Breed-Specific Shedding

    • Some breeds, such as greyhounds, golden retrievers and Irish setters, are prone to excessive canine shedding. This is breed-specific shedding and is not a cause for concern, as the fur grows back. But it is best to consult a vet to ensure that no health conditions exist along with the shedding.

    Tips to Handle Canine Shedding

    • Brush and bathe your pet regularly to remove excess hair. The loose strands of fur will collect on the brush or get washed away.
