Dog Behavior: Why Does My Dog Lick My Other Dogs Eyes?
Does your dog lick their canine companions’ eyes? This behavior, while sometimes concerning to pet parents, is often a normal and healthy part of canine grooming behavior and dog social grooming. Dogs lick each other’s eyes for a variety of reasons, including hygiene, affection, and to reinforce social bonds. It’s a fascinating glimpse into their pack mentality and how they communicate.
The Roots of Eye Licking in Dogs
Canine eye licking is a behavior that stems from their wild ancestors. In wolf packs, grooming is a vital social activity. It strengthens relationships, reduces stress, and helps maintain the health of the pack. Dogs have carried these instincts into their domestic lives, transferring these behaviors to their human families and their canine housemates.
Hygiene and Health
One of the primary reasons dogs engage in dog mutual licking, including around the eyes, is for hygiene. Just like humans groom themselves, dogs groom each other to keep clean. This can involve licking ears, faces, and yes, even the areas around the eyes. They might be removing debris, dried mucus, or any irritants that have accumulated in the eye area. This is a natural part of maintaining good dog health and licking practices within the social group.
- Removing Discharge: Tears and other natural eye secretions can sometimes create a buildup. A fellow dog might lick this away as a helpful act of cleaning.
- Soothing Irritation: If a dog has a minor irritation in their eye, such as a stray hair or dust, another dog might lick the area, potentially offering a soothing effect.
- Checking for Health Issues: While dogs aren’t veterinarians, they are attuned to their pack members’ well-being. Licking might be a way they check if their companion is feeling well, especially around sensitive areas like the eyes.
Affection and Bonding
Beyond simple cleanliness, eye licking is a powerful expression of affection and a way to strengthen the bond between dogs. Think of it as a doggy hug or a gentle pat on the back. When dogs lick each other’s faces, especially around the eyes and muzzle, they are showing care and connection. This is a key component of dog social grooming.
- Reinforcing Pack Ties: In a domestic setting, your dogs form a pack. Mutual grooming, including eye licking, reinforces their social hierarchy and their sense of belonging to the group.
- Comfort and Reassurance: A dog might lick another’s eyes as a sign of comfort, especially if the other dog seems stressed or anxious. This can be a form of dog comfort licking.
- Submissive Greetings: Lower-ranking dogs might lick the faces of higher-ranking dogs as a sign of respect and deference. This is a form of dog appeasement behavior.
Play and Interaction
Sometimes, eye licking can be part of playful interaction between dogs. While not as common as roughhousing or chasing, gentle licking can be a way for dogs to engage with each other during calmer moments of play. It’s a less boisterous form of interaction that still serves to keep them connected.
When Eye Licking Might Indicate a Problem
While generally a harmless behavior, there are instances where excessive eye licking can signal an underlying issue. It’s important for owners to observe the context and frequency of the licking.
Excessive Licking and Irritation
If one dog is constantly and intensely licking another dog’s eyes, it could indicate that the licked dog is experiencing discomfort or pain in that area. This is where dog excessive licking becomes a flag.
- Eye Infections: Bacterial or viral infections can cause irritation, discharge, and discomfort, prompting a companion dog to lick the affected eye.
- Allergies: Environmental or food allergies can manifest as itchy, watery eyes, leading to persistent licking by another dog.
- Foreign Objects: Something as simple as a piece of dust, an eyelash, or even a small insect lodged in the eye can cause irritation and attract licking.
- Injuries: A scratch on the cornea or other minor eye injuries can cause pain and discomfort.
Behavioral Issues
In rarer cases, dog excessive licking of another dog’s eyes might be related to underlying behavioral problems.
- Anxiety or Stress: A dog experiencing anxiety might exhibit compulsive licking behaviors, sometimes directed at their housemates.
- Obsessive-Compulsive Disorder (OCD): Though uncommon, some dogs can develop OCD, which might manifest as excessive grooming of themselves or others.
Recognizing the Signs
Observing your dogs’ interactions is key. Here’s what to look for:
- Body Language: Is the dog being licked showing signs of discomfort (flinching, turning away, vocalizing)? Or do they seem relaxed and accepting? Is the licking dog calm and gentle, or persistent and forceful?
- Frequency and Duration: Is the licking occasional and brief, or is it happening for extended periods and very frequently?
- Other Symptoms: Is the dog whose eyes are being licked showing any redness, swelling, discharge, squinting, or pawing at their eyes?
What to Do If You’re Concerned
If you notice your dog licking another dog’s eyes in a way that seems problematic, here’s what you can do:
Veterinary Consultation
The first and most important step is to consult with your veterinarian. They can perform a thorough eye examination to rule out any medical issues.
- Rule Out Medical Causes: Your vet can diagnose and treat eye infections, allergies, injuries, or the presence of foreign bodies.
- Address Underlying Conditions: If there’s a systemic health issue contributing to eye problems, your vet can help manage it.
Behavioral Support
If medical causes are ruled out, you might need to consider behavioral interventions.
- Management: If the licking is occurring during specific times or situations, you can try to manage those environments. For example, if it happens when one dog is anxious, providing a calming presence or redirection might help.
- Redirection: If you catch your dog in the act of excessive eye licking and you suspect it’s not for hygienic reasons, gently redirect their attention to a toy or a different activity.
- Professional Behaviorist: For persistent or concerning behavioral issues, seeking advice from a certified professional dog trainer or a veterinary behaviorist can be invaluable. They can help identify the root cause of the behavior and develop a tailored training plan.
Distinguishing from Other Licking Behaviors
It’s useful to differentiate eye licking from other common canine licking behaviors.
Anal Gland Expression
While seemingly unrelated, understanding that dogs lick themselves and each other for hygiene can draw parallels. For instance, sometimes dogs may lick around their anal glands if they are experiencing discomfort or impaction. This is a different type of hygiene-related licking but highlights how dogs attend to bodily needs and those of their pack. However, direct dog anal gland expression by another dog is not a typical behavior. If a dog appears to be licking another’s anal area excessively, this could indicate a medical issue for the dog being licked and should be checked by a vet.
General Comfort Licking
Many dogs lick their owners or their companions as a general sign of affection and dog comfort licking. This can include licking paws, legs, or faces. Eye licking falls within this spectrum of affectionate grooming.
Licking as a Stress Indicator
Sometimes, dog excessive licking can be a self-soothing mechanism or a displacement behavior when a dog is stressed or anxious. This might be directed at themselves, their toys, or their housemates, including licking around the face and eyes.
Common Scenarios and Their Interpretations
Let’s look at some typical situations involving dog eye licking:
| Scenario | Possible Interpretation |
|---|---|
| Gentle, brief licking of a sleepy dog’s eye | This is likely canine grooming behavior aimed at cleaning away sleep crusts. It’s a sign of care and attention within the pack. This is a common form of dog mutual licking. |
| One dog meticulously grooming another’s face | This is dog social grooming in action. It reinforces their bond and can be an act of affection. The licking might extend to the eye area as part of this broader grooming ritual. This can be seen as dog comfort licking. |
| A younger dog licking an older dog’s eyes | This can be a sign of respect and dog appeasement behavior. The younger dog is showing deference to the senior member of the “pack.” It’s also a way to solicit attention and affection. |
| One dog persistently licking another dog’s eye, who is squinting or trying to pull away | This could indicate that the licked dog has an eye irritation, infection, or foreign object. The persistent licking might be an attempt to alleviate discomfort, or the licking dog might be detecting an issue and trying to help. This is a situation where dog excessive licking warrants attention and a vet visit for the dog being licked. It could be a sign of a problem with their dog health and licking. |
| A dog licking their own eyes excessively | While this isn’t about licking another dog, excessive self-licking of the eyes can also indicate an eye problem or a compulsive behavior. |
The Impact on the Dog Being Licked
Generally, mild and occasional eye licking by another dog is harmless. However, if the licking is rough, too frequent, or if the licked dog shows distress, it can be problematic.
- Potential for Irritation: Constant or rough licking could potentially irritate the delicate tissues of the eye or surrounding skin.
- Spread of Germs: While dogs groom each other, if one dog has an infection (ocular or otherwise), excessive licking could potentially transfer germs.
- Masking Issues: If one dog is constantly licking the eyes of another, it might inadvertently mask a developing eye problem that you would otherwise notice due to the dog pawing at its eyes or excessive discharge.
Frequently Asked Questions (FAQ)
Q1: Is it normal for my dogs to lick each other’s eyes?
A1: Yes, it is often normal. Dog mutual licking, including around the eyes, is a part of canine grooming behavior, affection, and dog social grooming. It can be a way of cleaning, showing care, and reinforcing their bond.
Q2: When should I worry about my dog licking another dog’s eyes?
A2: You should worry if the licking is excessive, rough, or if the dog being licked shows signs of discomfort such as squinting, pawing at their eyes, redness, swelling, or discharge. This could be a sign of an eye issue requiring veterinary attention, and dog excessive licking can be a red flag for dog health and licking concerns.
Q3: Can licking cause an eye infection in my other dog?
A3: While generally unlikely, if one dog has a contagious eye infection and is licking another dog’s eyes frequently, there’s a theoretical possibility of transmission. However, mild grooming is usually not an issue.
Q4: My dog licks my other dog’s eyes constantly. What should I do?
A4: First, observe the dog whose eyes are being licked. If they show any signs of distress or eye problems, schedule a visit with your veterinarian immediately. If no medical issue is found, you might consider consulting a professional dog behaviorist to address potential compulsive or anxiety-driven licking.
Q5: What’s the difference between friendly licking and problematic licking?
A5: Friendly licking is usually gentle, brief, and reciprocated or accepted by the other dog. Problematic licking is often persistent, forceful, and the recipient dog shows signs of discomfort or attempts to avoid it. This excessive behavior can sometimes indicate underlying health or behavioral issues, making it important to consider dog health and licking.
Q6: Could eye licking be related to dog anal gland issues?
A6: No, direct dog anal gland expression is not a common behavior between dogs, and licking around the anal area is usually a self-grooming behavior or a sign of discomfort in the dog doing the licking. Eye licking is a separate behavior, typically related to grooming or affection of the facial area.
In conclusion, while the sight of your dog licking another dog’s eyes might initially raise an eyebrow, it’s most often a benign and even positive social interaction. By observing your dogs’ body language and the context of the licking, you can determine if it’s a normal expression of their social bonds or a sign that a veterinary check-up is in order.
