Is It Normal for A Dog to Eat Hair

Many dog owners may find themselves puzzled or concerned when they notice their dog eating hair—whether it’s human hair found on the floor or their own fur. While this behavior can be unsettling, it is not uncommon. Dogs can eat hair for various reasons, ranging from boredom to underlying medical conditions. Understanding why dogs exhibit this behavior and the potential risks involved can help ensure the safety and well-being of your canine companion.

Is It Normal for A Dog to Eat Hair?

It is not unusual for dogs to eat hair, whether human hair or their own fur, but it’s not a normal or healthy behavior. Dogs may do this out of boredom, curiosity, or anxiety. While occasional ingestion may not cause harm, frequent hair consumption can lead to digestive issues or even intestinal blockages.

Why Do Dogs Eat Hair?

There are several reasons why a dog might eat human hair or its own fur:

1. Boredom or Anxiety

Dogs may chew or eat hair due to boredom or anxiety. Similar to how some dogs chew on furniture or dig holes when they are not mentally stimulated, eating hair can be a way for dogs to occupy themselves. Anxiety, particularly separation anxiety, can also lead to compulsive behaviors such as hair consumption.

2. Exploration and Curiosity

Dogs are naturally curious creatures that explore the world through their mouths. Puppies, in particular, tend to eat things they shouldn’t, including hair, as part of their exploration of new textures and sensations. 

3. Pica

Pica is a behavioral disorder in which dogs compulsively eat non-food items. If your dog consistently eats hair or other inappropriate objects, pica may be the underlying cause. Pica can stem from nutritional deficiencies, boredom, stress, or other medical issues. It’s essential to consult a vet if your dog’s hair-eating behavior seems compulsive.

4. Allergies or Skin Irritation

A dog may eat its own hair if it is experiencing skin irritation due to allergies, fleas, or infections. The discomfort can lead to excessive grooming, where the dog chews or pulls out fur to relieve the itch. In some cases, the dog may even ingest the hair after pulling it out.

5. Attention-Seeking Behavior

Dogs are social animals, and they quickly learn what behaviors get a reaction from their owners. If you react strongly when your dog eats hair, they might continue doing it as a way to get your attention.

What Happens If Dogs Eat Hair?

While it may seem harmless if your dog occasionally eats a strand of human hair or a clump of its own fur, the ingestion of hair can lead to several health issues. Here are some of the potential risks associated with dogs eating hair:

1. Digestive Discomfort

Hair is indigestible, meaning it cannot be broken down by your dog’s digestive system. In small quantities, hair will often pass through the intestines and be expelled in the feces. However, in larger amounts, hair can accumulate and form a mass, causing discomfort and other digestive issues.

2. Vomiting

If a dog consumes too much hair, its stomach may become irritated, leading to vomiting. This is often the body’s way of trying to expel the indigestible material. While vomiting might resolve the issue in some cases, it can also be a sign that the hair is causing a blockage, especially if it occurs frequently.

3. Blockages

The most serious risk of a dog eating hair is the potential for an intestinal blockage. Hair can form tight clumps or “hairballs” in the digestive tract, similar to how cats experience hairballs from grooming themselves. When this happens, it can block the intestines, preventing food and water from passing through the digestive system properly. If not treated promptly, blockages can become life-threatening and may require surgery to remove.

4. Diarrhea

In some cases, the ingestion of hair can irritate a dog’s intestines and cause diarrhea. The hair itself may not directly cause diarrhea, but it can lead to digestive upset that results in loose stools. Diarrhea can also be a sign of a blockage, especially if accompanied by vomiting, lethargy, or a refusal to eat.

Can a Dog Get a Blockage from Eating Hair?

Yes, dogs can develop an intestinal blockage from eating hair. When a significant amount of hair is consumed, it can accumulate in the stomach or intestines, forming a mass. This is particularly concerning if the dog is consuming its own fur through excessive grooming or is repeatedly eating human hair found on the floor or furniture.

Signs of a Hair-Induced Blockage:

• Repeated vomiting, especially after eating or drinking
• Loss of appetite
• Lethargy or weakness
• Abdominal pain or bloating
• Difficulty defecating or complete lack of bowel movements

If you notice any of these symptoms in your dog, it’s crucial to seek veterinary attention immediately. A blockage can be life-threatening if not treated, and surgery may be required to remove the obstruction.

Can Eating Hair Cause Diarrhea in Dogs?

Yes, eating hair can cause diarrhea in dogs, especially if the hair irritates the digestive system. When hair is ingested, it can disrupt the normal functioning of the intestines, leading to inflammation or irritation. This can cause the dog to have loose stools or diarrhea.

In some cases, diarrhea might be mild and resolve on its own once the hair passes through the system. However, if the diarrhea persists or is accompanied by other symptoms like vomiting or lethargy, it could be a sign of a more severe issue such as a blockage.

How to Prevent Your Dog from Eating Hair

Preventing your dog from eating hair is essential to avoid the potential health risks associated with this behavior. Here are some tips to help discourage hair consumption:

1. Regular Grooming

Ensure your dog is groomed regularly to minimize the amount of loose fur they might ingest. Brushing your dog’s coat frequently will help remove excess hair and reduce the likelihood of them eating it during grooming.

2. Environmental Control

Keep your living space clean and free of loose hair. Regularly sweep or vacuum floors, especially in areas where your dog spends the most time, to remove any human hair that could be ingested.

3. Behavioral Training

If your dog is eating hair as an attention-seeking behavior, it’s essential to discourage this habit. Avoid reacting strongly when you catch your dog eating hair, and instead, offer positive reinforcement when they exhibit desired behaviors.

4. Provide Mental Stimulation

Boredom is a common cause of dogs engaging in inappropriate behaviors, including eating hair. Ensure your dog is mentally stimulated through interactive toys, puzzles, and regular exercise to keep them engaged and prevent boredom.

5. Consult a Vet

If your dog’s hair-eating behavior seems compulsive or is accompanied by signs of distress, it’s essential to consult a veterinarian. They can determine whether an underlying medical condition, such as pica or allergies, is contributing to the behavior and recommend appropriate treatment.

Frequently Asked Questions (FAQs)

Is it normal for dogs to eat human hair?

While it’s not uncommon for dogs to eat human hair, especially if they find it on the floor or furniture, it’s generally not considered a normal or healthy behavior. Regular ingestion of hair can lead to digestive issues and should be discouraged.

Can a dog get sick from eating hair?

Yes, eating hair can cause digestive upset, including vomiting and diarrhea. In more severe cases, hair can accumulate in the stomach or intestines, leading to a blockage that may require surgery to remove.

What should I do if my dog ate hair?

If your dog ate a small amount of hair, it will likely pass through the digestive system without issue. However, monitor your dog for signs of distress, such as vomiting, lethargy, or diarrhea. If these symptoms occur, contact a vet immediately.

Can dogs pass hair naturally?

In small quantities, dogs can often pass hair naturally through their stools. However, larger amounts of hair may accumulate and cause blockages, which can be dangerous and require veterinary intervention.

How can I stop my dog from eating hair?

To prevent your dog from eating hair, keep your environment clean by regularly sweeping or vacuuming, provide mental stimulation, and ensure regular grooming to reduce the amount of loose fur. If the behavior persists, consult a vet for further advice.

Conclusion

While it may seem harmless at first, dogs eating hair can pose significant health risks. Whether they are consuming human hair found around the house or their own fur due to grooming, the ingestion of hair can lead to digestive issues, including vomiting, diarrhea, and even life-threatening blockages. Understanding the causes behind this behavior and taking proactive steps to prevent it can help keep your dog safe and healthy. If you’re ever in doubt or notice troubling symptoms, don’t hesitate to consult your veterinarian.
