Why Do Dogs Lick Their Wounds? Understanding the Behavior and Implications

Dogs often lick their wounds, and there’s a biological reason behind this behavior. When your dog licks its wounds, it’s driven by instinctive behavior that’s rooted in the healing processes common to many animals. The act of licking delivers saliva to the wound, which contains beneficial enzymes and can help clean away debris. Moreover, the mild abrasive action of the tongue can aid in keeping the wound free from dead tissue and dirt.

However, excessive licking may not always be beneficial and can lead to complications. Your dog’s saliva may help initially, but repeated licking can irritate the wound and disrupt the healing process. It’s also important to consider that a dog’s mouth carries bacteria, which can potentially infect the wound. As a pet owner, it’s vital to monitor your dog’s wound-licking behavior and seek veterinary advice if there are signs of infection or if the wound does not improve.

Canine Wound-Care Behavior

When your dog sustains a wound, it often turns to licking as a primary form of care. This behavioral instinct is deeply ingrained in dogs as a method to stimulate healing. By licking their wounds, they remove debris and lower the chance of infection.

Licking wounds comes from an instinctual drive, likely honed through natural selection due to its survival benefits. However, excessive licking can be harmful, leading to irritation or infection. Thus, balance in this behavior is essential.

Understanding why dogs lick their wounds demonstrates the intersection of instinct and learned behavior. While the licking can help to clean a wound initially, it’s important for you to monitor your dog to ensure the behavior remains beneficial rather than detrimental.

Medical Perspective on Licking

From a medical standpoint, when your dog licks its wounds, it might be doing so to clean the area or provide soothing relief from irritation. However, this behavior can also introduce harmful bacteria, potentially complicating the healing process.

Healing or Harm?

Dogs instinctively lick their wounds, but the medical community is divided on the benefits versus the risks of this behavior. On one hand, dog saliva contains compounds that can be antibacterial, such as lysozyme and lactoferrin, which can help clean wounds by removing debris and potentially reducing infection. This natural response can also serve to soothe perceived pain or irritation.

On the other hand, licking can cause harm by introducing pathogenic bacteria, like Escherichia coli (E. coli), Streptococcus canis, or Pasteurella, which can complicate the recovery process and lead to serious infections. Furthermore, excessive licking can reopen sutures after surgery and delay healing, as saliva can moisten and weaken bandages, making them less effective.

Veterinary Interventions

Veterinarians may recommend interventions to prevent dogs from licking their wounds excessively. A common solution is the application of a bandage to protect the area. If the bandage is not enough, using an Elizabethan collar, often referred to as a “cone of shame,” can help by physically blocking your dog’s access to the wound.

Medically, vets might apply antiseptic or medicine to wounds both to accelerate healing and to provide an antimicrobial barrier against infection. If there is a risk of bacteria causing an infection, a veterinarian might prescribe antibiotics to treat or prevent infection. It’s essential for you to follow your vet’s guidance on wound care to promote safe and rapid healing, which includes monitoring the wound for signs of infection or irritation and changing bandages as directed.
