Why is My Dog Shedding More in the Winter? Exploring Seasonal Coat Changes

As winter approaches, many pet owners notice a significant increase in their dog’s shedding. This can be somewhat perplexing, as we often associate shedding with the warmer months of the year. However, shedding in dogs is not limited to summer and can actually increase in the winter for a variety of reasons. In this article, we will explore why dogs shed more in the winter and provide answers to some common questions about seasonal coat changes.

Understanding the Basics of Shedding

Before delving into why shedding occurs more in the winter, it is essential to understand the basics of shedding in dogs. Shedding is a natural process that allows dogs to replace their old or damaged fur with a new one. It helps regulate body temperature, protects the skin, and promotes overall coat health.

The amount of shedding varies from dog to dog, mainly dictated by their breed, genetics, and overall health. Some breeds are considered heavy shedders, such as Huskies, Retrievers, and German Shepherds, while others shed minimally, like Poodles or Afghan Hounds. Additionally, factors such as age, diet, and environment can influence shedding patterns.

Why Dogs Shed More in the Winter Dog Shedding More in the Winter

Contrary to popular belief, dogs do not shed more during winter due to the cold weather. Instead, several factors contribute to increased shedding during the colder months:

1. Temperature Regulation:

During winter, dogs grow a thicker undercoat to provide insulation and keep them warm in low temperatures. This thick undercoat is shed in the spring to make way for a lighter summer coat. Due to hormonal changes triggered by changes in daylight hours, dogs may experience a shedding phase during the winter, which serves to remove old undercoat and make room for the new one.

2. Indoor Heating:

Indoor heating systems contribute to a loss of humidity, resulting in drier air. The dry environment can accentuate shedding by drying out a dog’s skin, leading to irritation and excessive hair loss. Dogs in heated environments might experience more shedding than those kept in natural, unheated settings.

3. Artificial Lighting:

In areas with fewer daylight hours during winter, many dog owners rely on artificial lighting to extend the dog’s activity time outdoors. This artificial lighting can interfere with dogs’ natural shedding patterns, signaling to their bodies that it is still summer or spring and encouraging them to retain their undercoat.

4. Stress and Anxiety:

Changes in routine, holiday decorations, or increased indoor activities during winter can cause stress or anxiety in some dogs. Stress can contribute to hormonal fluctuations, triggering an increase in shedding. Additionally, anxiety-induced behaviors like excessive scratching or licking can lead to hair loss and shedding.

Managing Winter Shedding

While it is impossible to entirely prevent shedding, some measures can be taken to minimize the impact of increased shedding during winter:

1. Regular Brushing:

Regular brushing helps remove loose and dead hair, preventing it from falling off around the house. Depending on your dog’s breed, consider using an appropriate grooming tool, such as a slicker brush for longer-haired breeds or a shedding blade for double-coated dogs. Frequent brushing also helps distribute natural oils, promoting a healthier coat.

2. Bathing and Conditioning:

Keeping your dog clean and well-moisturized can minimize shedding caused by dry skin. Use a gentle, dog-specific shampoo and conditioner, ensuring that the products are suitable for their coat type and skin condition.

3. Keeping Indoor Humidity Levels Balanced:

Using a humidifier, especially if you rely on indoor heating, can help combat dry air and prevent excessive shedding. Maintaining an optimal humidity level of around 30-50% can also benefit your dog’s overall respiratory health.

4. Consistent Diet and Nutrition:

Providing your dog with a balanced and nutritious diet is crucial for maintaining a healthy coat. Omega-3 fatty acids found in fish oil or supplements can improve coat condition and reduce shedding. Consult your veterinarian to determine the best diet plan for your dog’s specific needs.

5. Stress Management:

Create a calm and stress-free environment for your dog during the winter months. Stick to a routine, engage in regular exercise, and provide mental stimulation through interactive toys or training sessions. If your dog experiences severe anxiety or stress, consult with a professional trainer or veterinarian for further guidance.

Frequently Asked Questions (FAQs)

1. Is increased shedding in the winter normal for all dogs, or does it vary by breed?

While increased shedding is common in many dogs during the winter months, the degree of shedding can vary by breed. Dogs with double coats, such as Huskies or Retrievers, typically shed more as they grow and shed their undercoat. Breeds with shorter coats, like Greyhounds or Boxers, may not show significant seasonal changes in shedding.

2. Should I be concerned if my dog sheds more than usual during winter?

In most cases, increased shedding during the winter is a normal process. However, if you notice excessive or sudden shedding, accompanied by other symptoms like hair loss, dry skin, or a change in appetite, it is advisable to consult a veterinarian. These signs could indicate an underlying health issue that requires attention.

3. Can certain dietary changes help minimize shedding in the winter?

Providing your dog with a nutritionally balanced diet is important for maintaining a healthy coat. Including omega-3 fatty acids in their diet, either through food or supplements, can improve coat condition and reduce shedding. Consult your veterinarian to determine the ideal diet plan for your dog.

4. Are there any natural remedies that can help manage shedding in the winter?

While there is no magic solution to completely eliminate shedding, some natural remedies can help manage it. Regular brushing, moisturizing shampoos, and conditioners, and maintaining optimal indoor humidity levels can alleviate shedding symptoms. In some cases, certain supplements like biotin or fish oil can also support coat health. However, always consult with a veterinarian before introducing any new supplements or remedies to your dog’s routine.


Seasonal shedding in dogs is a natural process, and increased shedding during winter is not unusual. Understanding the factors contributing to winter shedding, such as temperature regulation, indoor heating, artificial lighting, and stress, can help pet owners manage their dog’s shedding more effectively. By following grooming routines, maintaining optimal humidity levels, providing a nutritious diet, and managing stress, you can minimize the impact of shedding and keep your dog’s coat healthy and shiny throughout the winter season.
