Reasons why dogs lick wounds

Dogs are known for their loyal and affectionate nature towards their owners. They have a natural instinct to take care of their pack members, and this includes attending to any injuries or wounds they may have. If you’ve ever had a dog, you may have noticed them licking their wounds. While it may seem odd to us humans, there are actually several reasons why dogs engage in this behavior.

1. Self-Cleaning Mechanism: Dogs have a natural tendency to keep themselves clean, and licking wounds is part of their self-cleaning mechanism. When a dog licks a wound, the saliva acts as a natural disinfectant. It contains enzymes that help to kill bacteria and prevent infection. Additionally, the moisture from the saliva helps to keep the wound clean and moist, promoting faster healing.

2. Pain Relief: Licking wounds also provides dogs with a certain level of comfort and pain relief. When a dog licks a wound, it stimulates the release of endorphins in their brain, which act as natural painkillers. This is similar to how we as humans might rub or massage a sore area to alleviate pain. However, it’s important to note that excessive licking can actually worsen the wound or delay the healing process, so it’s important to monitor the licking behavior and take necessary precautions.

3. Healing Process: Dogs’ saliva contains special enzymes, such as lysozyme, which has antibacterial properties that can help in the healing process. Lysozyme helps to break down the biofilm that bacteria form on wounds, making it easier for the immune system to fight off potential infections. Additionally, licking increases blood flow to the injured area, promoting faster healing by bringing essential nutrients and oxygen to the area.

4. Social Bonding: Dogs have a strong instinct to care for their pack members, and licking wounds can be a way for them to demonstrate their affection and form a social bond. It’s their way of saying, “I’m here for you, and I’ll take care of you.” This behavior is more common in dogs that have a close relationship with their owners or other household members.

5. Stimulation of Tissues: Licking wounds provides dogs with sensory stimulation, particularly for wounds that may be itchy or painful. The licking action can help to remove dead tissue or debris from the wound, which might otherwise impede the healing process.

However, despite the potential benefits of dogs licking wounds, there are some risks to be aware of. Excessive licking can lead to further trauma to the wound, making it worse or delaying healing. It can also introduce more bacteria into the wound, increasing the risk of infection. Therefore, it’s crucial to balance the positive aspects with appropriate wound care and monitoring.

If you notice your dog excessively licking a wound, it’s essential to consult with a veterinarian. They can assess the severity of the wound and provide appropriate medical treatment, such as cleaning the wound and applying a protective dressing. In some cases, a veterinarian may recommend using an Elizabethan collar or bitter-tasting deterrents to prevent excessive licking.

In conclusion, while it may seem strange to us humans, there are valid reasons why dogs lick wounds. It’s a natural behavior driven by their instincts to self-clean, provide comfort, assist in healing, and bond with their owners. However, it’s crucial to monitor this behavior and take necessary precautions to ensure proper wound care and healing. Consulting with a veterinarian is always a wise decision when it comes to your dog’s health and wellbeing.
