Why Dogs Lick Wounds and the Risks Involved
Your dog's instinct to lick a wound is understandable, driven by an innate cleaning behaviour and the potential presence of soothing saliva. However, while their intentions might be good, allowing a dog to continuously lick an injury can significantly hinder healing and introduce new problems. Dog saliva, while containing some antiseptic properties, also harbours bacteria that can lead to infection. Persistent licking can also reopen stitches, irritate the skin, and prevent the formation of a protective scab, turning a minor ailment into a chronic issue.
The risks are substantial. Beyond infection, excessive licking can cause inflammation, delay healing times, and even lead to secondary skin conditions. For surgical sites, it's paramount to prevent disruption, which licking is almost guaranteed to cause. Similarly, for abrasions or insect bites, the constant moisture and friction from licking can create a breeding ground for bacteria, potentially worsening the condition or leading to a painful, localised infection. Understanding these risks highlights why intervention is necessary.
It's important to recognise when licking is excessive. A quick, exploratory lick might be normal, but constant, obsessive licking, particularly if the dog seems fixated on the area, signals a problem that needs addressing. This behaviour can also be a sign of discomfort or pain, prompting further investigation into the wound's condition. Therefore, the first step in managing a wound is to assess the licking behaviour and its potential consequences.
Assessing the Wound and Licking Behaviour
Before implementing any preventative measures, a thorough assessment is vital. Examine the wound for signs of infection, such as increased redness, swelling, discharge (pus), or a foul odour. Note the wound's size, depth, and location. Is it a superficial scrape, a surgical incision, or something more serious like a deep cut or a ruptured cyst? Simultaneously, observe your dog's licking habits. Are they merely sampling the area, or are they obsessively grooming it? This initial assessment will inform the best approach to prevent further licking and ensure appropriate care.
The primary goal is to create a barrier that discourages licking without causing undue stress to your dog.
Physical Barriers: The First Line of Defence
When your dog has a wound, physical barriers are often the most reliable way to prevent licking. These methods create a physical separation between your dog's mouth and the injury, allowing the wound to heal undisturbed. The choice of barrier depends on the wound's location, size, and your dog's temperament and size.
The Elizabethan Collar (E-collar)
The classic 'cone of shame', or Elizabethan collar (E-collar), is a widely used and effective tool. These plastic or fabric cones attach around your dog's neck, extending outwards to prevent them from reaching most parts of their body. While some dogs find them cumbersome and may initially try to remove them, they are typically the most foolproof method for preventing licking, especially for wounds on the torso, legs, or tail. Modern E-collars come in various lengths and flexibilities to improve comfort.
Inflatable Collars and Soft Collars
For dogs who struggle with rigid E-collars, inflatable collars can be a more comfortable alternative. These look like large neck pillows and restrict head movement sufficiently to prevent access to most wounds. Soft fabric collars offer a similar, less restrictive option but might not be suitable for dogs determined to reach certain areas. Always ensure the collar is fitted correctly, allowing your dog to eat, drink, and sleep comfortably while still preventing access to the wound.
Protective Vests and Bodysuits
For wounds on the torso or limbs, a specialised dog recovery suit, vest, or even a clean, well-fitting t-shirt or sock can provide a barrier. These garments cover the wound and make it physically difficult for the dog to lick. Ensure the garment is breathable and does not rub against the wound. For male dogs, ensure the suit doesn't interfere with urination. These are particularly useful for post-surgical sites or larger abrasions. Always check the fit to ensure it doesn't restrict breathing or movement excessively.
Fit any protective collar or garment properly; a loose E-collar won't prevent licking, and a tight one will cause distress.
Bandaging and Wound Dressings
When applied correctly by a veterinary professional, bandages can protect wounds and deter licking. However, it's crucial that bandages are changed regularly and kept clean and dry. If a bandage becomes loose, wet, or soiled, it can harbour bacteria and attract your dog's attention, potentially leading to them chewing it off and exposing the wound. Always follow veterinary advice regarding bandage care. For some superficial wounds, a specialised wound dressing might be sufficient without a full bandage.
The most critical aspect of using physical barriers is ensuring they are worn consistently and correctly for the duration recommended by your vet.
Deterrents and Behavioural Modifications
While physical barriers are primary, deterrents and behavioural modifications can support wound management. These methods aim to make the wound area unappealing or redirect your dog's attention, working alongside physical protection for enhanced effectiveness.
Taste and Scent Deterrents
A variety of sprays and topical solutions are available that have bitter or unpleasant tastes and smells designed to deter licking. These are typically applied around the wound site (never directly into an open wound unless instructed by a vet). Common ingredients include bitter apple or quinine. When applying, ensure you cover the area your dog can reach, not just the wound itself. Test a small area first to ensure your dog doesn't have a sensitivity. Some dogs, however, are not deterred by these tastes and will lick through them, so their effectiveness varies greatly.
Distraction and Enrichment
Sometimes, a dog's licking is a manifestation of boredom, anxiety, or habit. Providing plenty of mental and physical stimulation can help redirect their energy. Engage your dog in short, gentle play sessions or training exercises. Puzzle toys filled with healthy treats can keep them occupied for extended periods, diverting their focus from the wound. Ensure they have comfortable resting places away from the wound area. If the licking is a persistent behavioural issue, consult a veterinary behaviourist.
For wounds that are difficult to cover, like those on paws or faces, a combination of a deterrent spray and constant supervision is often necessary.
Supervision and Interruption
When other methods are insufficient or when the wound is particularly vulnerable, direct supervision is key. If you see your dog attempting to lick the wound, interrupt them gently with a sound or a touch and immediately redirect their attention to an approved activity or toy. This requires vigilance, especially during the initial stages of healing. For longer-term supervision needs, consider enlisting help from family members or friends.
It's important to note that some dogs, particularly those with skin conditions like yeast dermatitis or fungal skin conditions, may lick due to itchiness. Addressing the underlying cause is crucial for long-term licking prevention in these cases. Similarly, if the licking is linked to an underlying medical issue such as early stage Cushing's disease, seeking veterinary diagnosis is paramount.
When to Seek Veterinary Advice
While many minor wounds can be managed at home with the methods described, it's crucial to know when professional veterinary help is essential. Delaying veterinary care can lead to complications, increased pain for your dog, and longer recovery times. Your vet can accurately diagnose the severity of the wound and prescribe the most appropriate treatment plan.
Signs of Complication
Certain signs indicate that a wound is not healing as expected and requires immediate veterinary attention. These include:
- Increased redness, swelling, or heat around the wound.
- Presence of thick, coloured discharge (pus) or a foul odour.
- Wound edges that are pulling apart or failing to close.
- Excessive bleeding that doesn't stop with gentle pressure.
- Your dog showing signs of significant pain, lethargy, or fever.
- The wound appearing to worsen or not improve after a few days of home care.
These symptoms could indicate infection, a foreign object lodged in the wound, or a more serious underlying condition, such as a ruptured cyst or even a cancerous growth, which requires professional assessment and treatment.
Specific Wound Types
Certain types of wounds inherently require veterinary diagnosis and treatment. This includes deep puncture wounds (which can easily become infected internally), large or gaping lacerations, burns, and any wound suspected to be caused by a venomous bite or sting. If your dog has sustained a significant injury, or if you're unsure about the wound's nature, always err on the side of caution and consult your vet. This is also true for wounds that may be related to conditions like sebaceous gland cysts, which might require medical intervention.
Never attempt to suture or glue a wound yourself; this should only be performed by a qualified veterinarian.
Post-Surgical Care
If your dog has undergone surgery, their post-operative care is critical. Your vet will provide specific instructions on wound management, medication, and activity restriction. Preventing licking is often a top priority after surgery, and adherence to the prescribed E-collar or other protective measures is non-negotiable for successful healing and preventing complications like dehiscence (wound opening).
Remember, preventing a dog from licking a wound is about protecting them from themselves. By employing the right strategies and knowing when to seek professional guidance, you can ensure your canine companion heals quickly and comfortably.
Tips for Managing a Licking Dog
Managing a dog that is excessively licking a wound requires patience and a multi-faceted approach. Beyond the primary prevention methods, several practical tips can make the process smoother for both you and your pet.
Consistency is Key
Whatever method you choose, consistency is paramount. If you use an E-collar, ensure it stays on, day and night, unless specifically advised otherwise by your vet. If you're using a deterrent spray, reapply it as directed. If you're supervising, be diligent. Sporadic application or supervision will only prolong the healing process and increase the risk of complications. Your dog needs constant protection from their own licking behaviour.
Comfort and Monitoring
Ensure any protective device is as comfortable as possible. For E-collars, check for sharp edges and ensure it doesn't snag on things. For recovery suits, make sure they fit well and are made of breathable material. Regularly check the wound itself (as much as your dog's barrier allows) for any signs of irritation, infection, or changes. Keep the area around the wound clean and dry, following your vet's instructions for cleaning.
Introduce any new device like an E-collar gradually, offering praise and treats to associate it with positive experiences.
Veterinary Follow-Up
Adhere strictly to your veterinarian's follow-up schedule. They will monitor the wound's progress, remove stitches if necessary, and adjust the treatment plan as needed. Don't hesitate to contact your vet if you have any concerns, no matter how minor they may seem. Early intervention can prevent small issues from becoming significant problems. This is especially true if the wound might be related to underlying issues such as certain skin conditions or lumps that require further investigation.
The success of wound healing hinges on preventing the very behaviour that often accompanies injury: licking.
Addressing Underlying Causes
If your dog has a chronic issue causing them to lick, such as persistent itchiness from allergies, flea infestations, or skin infections, addressing the root cause is the only long-term solution. This might involve dietary changes, medication, or specialised grooming. Similarly, if a lump or skin lesion, like a sebaceous gland cyst, is causing discomfort, veterinary diagnosis will guide the appropriate management, which may include removal or treatment to stop licking. For dogs that are low shedding, their fur might trap moisture or irritants, necessitating careful grooming around wounds.
