Dogs are known for their licking habits, whether it’s the affectionate licks they give their owners or the incessant licking of their wounds. Although the latter may seem counterintuitive, it’s actually a natural instinct for dogs to lick their wounds as a way to promote healing. But what exactly does this behavior do to help with the healing process? In this blog post, we’ll explore the reasons why dogs lick their wounds and the science behind this seemingly strange behavior. So, let’s dive in and discover the fascinating world of canine healing.

Canine Healing: Understanding Why Dogs Lick Their Wounds

Dogs are natural lickers, and they often lick their wounds as part of their healing process. While it may seem gross to us humans, licking is an instinctual behavior that aids in the healing process for dogs. In this article, we will explore the reasons behind why dogs lick their wounds and how it benefits their healing process.

Why Do Dogs Lick Their Wounds?

1. Cleaning the Wound

One of the primary reasons dogs lick their wounds is to clean them. Licking helps to remove dirt, debris, and dead tissue from the wound, which can help prevent infection. While this may seem counterintuitive, saliva contains enzymes that can break down and kill bacteria, which can help keep the wound clean and free of infection.

2. Stimulating Blood Flow

Another reason dogs lick their wounds is to stimulate blood flow to the injured area. Licking causes the release of endorphins, which are natural painkillers that can help reduce pain and inflammation. Increased blood flow also helps to deliver nutrients and oxygen to the wound, which can help speed up the healing process.

3. Promoting Healing

Licking can also help promote healing in a number of ways. Saliva contains growth factors that can help stimulate the growth of new tissue and blood vessels. This can help the wound heal more quickly and reduce the risk of scarring.

4. Reducing Itching

Dogs may also lick their wounds to reduce itching and irritation. Licking can help to remove dead skin cells and other irritants that can cause itching and discomfort. Additionally, the moisture from saliva can help soothe the skin and reduce inflammation.

5. Self-Comforting

Finally, dogs may lick their wounds as a form of self-comforting. Licking can release endorphins, which can help reduce anxiety and stress. This can be particularly helpful for dogs who are in pain or feeling anxious about their injury.

Is It Always Safe for Dogs to Lick Their Wounds?

While licking can be beneficial for many wounds, it is not always safe for dogs to lick their wounds. If a wound is infected or has foreign material embedded in it, licking can actually make the situation worse. Additionally, excessive licking can cause the wound to become irritated and delay healing.

If your dog has a wound that you are concerned about, it is important to consult with your veterinarian. They can assess the wound and provide guidance on whether or not it is safe for your dog to lick it.


While it may seem gross to us humans, licking is a natural behavior that can be beneficial for dogs with wounds. Licking can help to clean the wound, stimulate blood flow, promote healing, reduce itching, and provide comfort. However, it is important to monitor your dog’s licking behavior and seek veterinary help if necessary. With proper care and attention, your dog can heal from their injuries and be back to their happy, healthy selves in no time.

In conclusion, dogs have been licking their wounds for centuries. It is a natural instinct that helps them heal faster and prevent infection. However, excessive licking can be harmful to their health and lead to more serious problems. As pet owners, it is important to observe our furry friends’ behavior and seek veterinary care if necessary. Understanding why dogs lick their wounds is just one small part of the complex relationship between humans and their loyal canine companions. By taking good care of our pets, we can help them live happy and healthy lives.
