Avoiding and Resolving Hair Loss in Dogs: Understand the Causes and Find Solutions

Are you concerned about the excessive hair shedding from your beloved pooch? While some of these issues may have physiological causes, there are many other factors at play. Find out more about the various causes, treatments, and preventive measures available to manage the excessive shedding of your pup.


Dogs naturally shed their hair, and it is a common trait among most breeds. While the shedding process in dogs is similar to humans, it can have certain effects. In this article, we will explore the causes, treatment, and prevention of hair loss in dogs, allowing you to address this health condition promptly.

1 Is Hair Loss in Dogs a Physiological Characteristic?

Hair loss in dogs can be considered a normal physiological phenomenon, as it is a part of their development and does not affect their overall health. Dogs typically shed their hair twice a year, with some shedding more near the “heat” season. Depending on the climate, dogs may shed less hair in the summer to cool down or change their coat to keep warm in the winter.

However, if a dog sheds excessive hair in patches or experiences hair loss accompanied by abnormal symptoms such as itching, rash, and peeling skin, it is no longer simply a physiological characteristic. It may be a sign of a hair loss disease in dogs, and further investigation and timely measures should be taken.

2 Causes of Hair Loss in Dogs


Allergies are a common cause of hair loss in dogs. Dogs are active and playful, often venturing into dense bushes or unclean places. This makes them susceptible to parasitic insects like fleas and ticks, as well as allergens like pollen and mold, which can cause diseases. Additionally, allergies to food or inappropriate shampoos can also lead to hair loss in dogs. Typical symptoms of allergies in dogs include itching, excessive scratching, biting, and hair loss in patches.

Parasitic Infestation or Bacterial Infection

Fungi, bacteria, or parasites can cause dogs to experience hair loss in patches, especially in areas such as the chest, abdomen, and around the ears and eyes. This is often accompanied by itchy and swollen skin due to repeated scratching, biting, and licking of the affected areas. In some cases, conditions like whipworm can cause hair loss in round or uneven shapes, as well as inflamed and infected skin.

Nutritional Deficiency

Diet plays a significant role in a dog’s health. Insufficient nutrients can lead to hair loss and dry skin. It is important to adjust the dog’s daily meals to ensure an adequate supply of necessary nutrients, promoting strong development, preventing skin diseases, and maintaining a shiny coat.

Cushing’s Disease

Cushing’s disease, also known as endocrine disorders, occurs when the body produces an excess of cortisol hormone compared to normal levels. This can be caused by natural imbalances or prolonged use of high-dose corticosteroid medications. Symptoms of Cushing’s disease in dogs include hair loss, darkened skin, swollen abdomen, excessive thirst, increased appetite, and fatigue. This condition typically affects middle-aged to older dogs.

Genetic Factors

Mating can unintentionally result in excessive hair loss in dogs due to the inheritance of unwanted characteristics or genetic diseases. Some breeds, such as Mexican hairless (Xolo), Dachshund, Chihuahua, and Whippet, are known to shed a lot of hair due to genetic factors.

Note: For effective treatment, it is recommended to take your dog to a veterinary clinic and consult with experts and veterinarians for advice.

Establish a Nutritious Regimen: Ensure the dog’s diet includes a balanced amount of nutrients, including proteins, vegetables, fruits, legumes, and healthy fats like olive oil. Provide an adequate supply of water and avoid excessively spicy foods.

Use Medications: Medications are available in various forms, such as injections, ointments, or oral medications. Consult with a veterinarian for advice and support in the treatment process. Some medications may stimulate hair growth.

Regular Brushing: Regularly brushing the dog’s coat helps remove old shedding hair, detangle the fur, and eliminate some dirt. It is also beneficial to use grooming products designed specifically for dogs to stimulate the growth of new, healthy hair and promote shine. Use a dedicated dog grooming comb and brush gently to help the dog relax.

Maintain Clean and Ventilated Environment: In hot and humid climates, harmful agents tend to develop. During the shedding season, use a vacuum cleaner to clean indoor environments and ensure the dog’s living space is clean and well-ventilated to prevent odors, bacteria, and mold. Clean the dog’s kennel and bedding at least once a week.
