Can Dogs Digest Hair?

Dogs are known for their indiscriminate eating habits, often gobbling up anything in sight. However, many pet owners wonder whether their furry friends have the ability to digest hair, as it is a common item found in their environment. Hair is found everywhere, from carpets and furniture to clothing and even in your pet’s food. Dogs have a reputation for being able to eat almost anything, but can their digestive system handle hair?

This article aims to explore the digestive system of dogs and whether or not they can digest hair, along with the potential risks associated with this habit. It will provide insights into the anatomy of a dog’s digestive system, as well as the impact ingesting hair can have on their health. By understanding the potential risks associated with dogs eating hair, pet owners can take the necessary steps to ensure their furry friends are safe and healthy.

Key Takeaway
Dogs can digest hair to some extent, but it depends on the quantity and length of hair ingested. Short, small amounts of hair are usually passed through the digestive system without causing any harm. However, if a dog ingests large quantities of long hair, it can get tangled up in their digestive system and cause an obstruction, which can be life-threatening. Regular grooming and monitoring your dog’s behavior can help prevent hair ingestion.

Understanding the Role of Digestive Enzymes in Dogs

Dogs have the ability to digest a variety of food items, including meat, grains, and vegetables. The process of digestion is a complex one that involves various enzymes and chemicals. In order for dogs to efficiently break down and utilize the nutrients in their food, their digestive system relies on specific enzymes.

Enzymes are proteins that facilitate chemical reactions in the body. Digestive enzymes, in particular, are responsible for breaking down carbohydrates, proteins, and fats into smaller components that can be absorbed and used by the body. Dogs have specific digestive enzymes that are tailored to their dietary needs. For example, they have an enzyme called amylase which helps break down starches from plant-based foods. Understanding the role of these enzymes in a dog’s digestive system can help dog owners make informed decisions about their pets’ diet and health.

Types of Hair and Their Digestibility in Dogs

When it comes to discussing a dog’s ability to digest hair, it’s essential to consider the types of hair that exist. The two main types of hair are fur and human hair. Fur is generally considered easier for dogs to digest, as it is thinner and more flexible than human hair. Dogs have evolved to digest fur as part of their natural diet, as it is often present on the prey they hunt.

On the other hand, human hair is more difficult for dogs to digest. Human hair is thicker and tougher, and can easily form a ball in the stomach or cause a gastrointestinal blockage. Ingesting human hair can also lead to complications such as vomiting, diarrhea, and abdominal pain. As a pet owner, it’s important to keep hair off the floor and prevent your dog from consuming excessive amounts of hair to avoid complications.

Common Symptoms of Hair Obstruction in Dogs

When a dog ingests hair, it can lead to hair obstruction, which refers to a blockage in the digestive system due to hair accumulation. The common symptoms of hair obstruction in dogs include vomiting, diarrhea, loss of appetite, abdominal pain, lethargy, and constipation. If you notice any of these symptoms in your dog, it is crucial to seek veterinary care immediately.

In severe cases, hair obstruction can even cause bowel obstruction or intestinal perforation, which can be fatal. If your dog has a habit of excessive licking or chewing their coat, it is essential to groom them regularly and keep their coat free from knots or mats to reduce the risk of hair ingestion. If you notice any signs of hair obstruction, take your dog to a vet immediately for assessment and treatment. Ignoring the symptoms can lead to severe complications, and your furry friend may require urgent surgery.

Prevention and Treatment of Hairballs in Dogs

Prevention is always better than cure when it comes to hairballs in dogs. One way to prevent hairballs is to regularly groom your dog. Brushing their coat regularly removes loose hair, reducing the amount of hair they swallow while grooming themselves. Additionally, feeding your dog a high-fiber diet helps to move hair through the digestive system, reducing the likelihood of hairballs.

In cases where prevention is not possible, there are several treatments for hairballs in dogs. Commercial hairball remedies can help to lubricate the digestive system and allow hairballs to pass through more easily. You can also try adding psyllium or pumpkin to their food, which can help to move hair through the system. If your dog is experiencing severe symptoms such as vomiting, lethargy, or loss of appetite, it is important to seek veterinary care immediately. Hairballs can become lodged in the digestive system and cause blockages, which can be life-threatening if left untreated.

Other Causes of Digestive Issues in Dogs Besides Hair

While hair ingestion can cause digestive issues in dogs, it is not the only cause. Other possible causes include dietary indiscretion (such as eating something outside that they shouldn’t), gastrointestinal infection or inflammation, parasites, foreign objects, and underlying medical conditions.

Dogs who have frequent digestive disorders may have underlying health issues, such as Irritable Bowel Disease (IBD) or food sensitivities. It is important to consult a veterinarian if you suspect your dog is experiencing digestive issues as some of these underlying conditions will require a proper diagnosis and treatment. By identifying and treating the root cause of the digestive issue, your dog can get back to their regular happy and healthy self!

Tips for Managing Your Dog’s Hair Consumption

While dogs consuming hair is not a major concern, it is important to ensure that they don’t eat an excessive amount. Eating a significant amount of hair can cause digestive issues, blockages, or even lead to internal injuries. Therefore, it is crucial to manage your dog’s hair consumption.

One effective way to manage your dog’s hair consumption is by brushing them regularly. This will remove loose hair and prevent it from falling to the ground, where your dog is likely to consume it. Additionally, ensuring a balanced diet with enough fiber can help prevent any potential blockages caused by hair. You can also give your dog chew toys to divert their attention from consuming hair. If your dog has an unusual urge to consume non-food items, it is important to consult with your veterinarian to rule out any underlying medical conditions. With appropriate measures in place, you can help ensure your furry friend stays healthy and happy.

When to Visit the Vet for Digestive Problems in Dogs

Digestive problems in dogs can be an indication of several issues, including the consumption of hair. While it’s not uncommon for dogs to occasionally consume hair, excessive ingestion can lead to digestive concerns like vomiting, diarrhea, and gastrointestinal obstruction. As a pet owner, it is important to recognize the signs of digestive problems and when to seek veterinary medical attention.

If your dog is experiencing digestive problems such as vomiting, sudden weight loss, or loose stools lasting more than a day, it is time to visit the vet. In some cases, the ingestion of hair may be a symptom of an underlying medical condition that requires immediate attention. Delaying a visit to the veterinarian can lead to serious complications or make the intervention process more difficult. Therefore, it’s important to pay attention to your dog’s eating habits and digestive system and seek external help when needed.


Dogs are known to chew on anything in their reach, including hair. It is not uncommon for them to swallow hair without facing any immediate issues. However, it is essential to remember that hair can cause blockages in the dog’s digestive system, leading to life-threatening complications.

Pet owners should monitor their dogs’ behavior and seek immediate veterinary help if their pets show signs of indigestion or discomfort after ingesting hair. The best way to prevent such incidents is by keeping the dog’s environment clean and removing any hair or fur in their reach. By taking precautionary measures, owners can ensure their furry friends’ safety and health.
