Why Dogs Eat Hair: Causes and Prevention


Watching your beloved dog eat hair can be an unsettling experience for many pet owners. While it may seem like a bizarre behavior, the truth is that hair eating is not uncommon among dogs. In this article, we will explore the causes of hair eating in dogs and the steps that you can take to prevent it from happening.

Causes of Hair Eating in Dogs

There are several reasons why dogs may eat hair. These include:


Dogs are social animals and need plenty of stimulation to keep them happy and healthy. If your dog is left alone for long periods of time, they may resort to chewing on objects, including hair, as a way to relieve their boredom.


Anxiety can also cause dogs to develop destructive behaviors, including hair eating. If your dog is experiencing separation anxiety or is in a stressful environment, they may turn to hair eating as a way to cope.

Nutritional Deficiencies

Dogs may also eat hair as a result of a nutritional deficiency. If your dog is not getting enough essential vitamins and minerals in their diet, they may seek out unusual food sources, such as hair.


Finally, some dogs may simply eat hair as part of their grooming routine. Dogs are known to groom themselves and others as a way of bonding and showing affection. In some cases, this may involve eating hair.

Prevention of Hair Eating in Dogs

Fortunately, there are several steps that you can take to prevent your dog from eating hair. These include:

Providing Adequate Stimulation

One of the best ways to prevent hair eating in dogs is to provide them with plenty of stimulation. This can include regular exercise, socialization with other dogs, and interactive toys that keep them engaged.

Addressing Anxiety

If your dog is experiencing anxiety, it is important to address the underlying cause of their stress. This may involve working with a professional dog trainer, providing more socialization opportunities, or addressing any environmental factors that may be contributing to their anxiety.

Providing a Balanced Diet

In order to prevent nutritional deficiencies, it is important to provide your dog with a balanced and nutritious diet. This can include high-quality dog food that is rich in essential vitamins and minerals, as well as supplements if necessary.

Providing Regular Grooming

Regular grooming can also help prevent hair eating in dogs. This can include brushing your dog’s coat regularly to remove loose hairs, as well as providing them with appropriate chew toys to satisfy their natural grooming instincts.


In conclusion, while hair eating in dogs may be a strange behavior, it is not uncommon. By understanding the causes of hair eating and taking steps to prevent it, you can help ensure that your beloved pet stays happy, healthy, and free from destructive behaviors.


Q: Why do dogs eat hair?

A: Dogs eat hair for a variety of reasons, including boredom, anxiety, or a medical condition. Some dogs may also eat their own hair or the hair of their housemates as a result of a compulsive behavior known as pica. It is important to identify the underlying cause in order to prevent the behavior from becoming a habit.

Q: What are the health risks of dogs eating hair?

A: Eating hair can lead to a number of health issues for dogs. Hairballs can become lodged in the digestive tract, causing blockages and potentially life-threatening conditions. Hair can also irritate the lining of the digestive tract, leading to vomiting, diarrhea, and other digestive problems.

Q: How can I prevent my dog from eating hair?

A: Prevention methods vary depending on the underlying cause of the behavior. Providing plenty of exercise and mental stimulation can help alleviate boredom and anxiety. For dogs with compulsive pica, behavior modification and medication may be necessary. Regular grooming can also reduce the amount of loose hair in the environment, making it less tempting for dogs to eat. If you suspect your dog may be eating hair due to a medical condition, it is important to consult with a veterinarian.
