Have you ever wondered why your dog obsessively licks other dogs? This common but puzzling behaviour often leaves owners curious and a little overwhelmed by the slobber involved. Understanding your dog’s licking habits can help maintain harmony in multi-dog environments and ensure every dog feels comfortable and respected.
Licking between dogs is a natural form of communication and greeting. It often expresses affection, appeasement signals, and submission, tracing back to behaviour seen in puppies with their dam. However, when licking becomes obsessive or persistent, it might signal anxiety, compulsion, or an underlying issue that needs attention.
For example, licking the mouth is generally a greeting or submissive gesture, but if prolonged, it can cause irritation or discomfort in the other dog. Observing the dogs’ reactions is vital to recognising when licking crosses the line from normal to problematic.
Not all dogs appreciate being licked, especially when it’s excessive or targeted at one dog repeatedly. Signs that indicate the need for intervention include:
If these signs occur, it’s important for owners to step in calmly and redirect the licking dog’s attention to more appropriate activities.
Licking around the mouth serves as both a greeting and a sign of submission. It echoes puppyhood behaviours where pups lick their mother’s lips, indicating trust and respect. To maintain positive interactions, redirect your dog once the greeting is complete to prevent obsession.
Ear licking is part of mutual grooming and can be enticing due to the scent of ear wax or food residues. This behaviour is often tolerated only briefly. If your dog focuses excessively on one dog’s ears, it might be wise to have those ears examined for possible infections by a vet.
Sniffing and licking genitals are natural canine greetings, rich in pheromone information. However, obsessive genital licking often causes frustration or defensive behaviour in the other dog. Persistent fixation on one dog’s private areas could signal a health issue that merits veterinary attention.
Quick Answer: Dogs lick other dogs’ mouths as a social greeting or sign of submission, but if obsessive, it may indicate anxiety or compulsive behaviour requiring attention.
Detailed Explanation: Mouth licking in dogs commonly originates from puppyhood and is a way to communicate peaceful intentions. However, obsessive mouth licking can develop as a coping mechanism for anxiety or as a compulsive habit. When your dog's licking persists beyond initial greetings, it risks irritating the other dog and affecting their relationship. Managing this behaviour typically includes training, redirection, and ensuring a relaxed environment during dog interactions.
Quick Answer: Use calm redirection techniques like commands, treats, and distractions to interrupt obsessive licking. Avoid harsh punishment as licking is a submissive behaviour.
Detailed Explanation: Intervention should be gentle to avoid increasing your dog's stress. Teach commands like "sit" or "leave it" before introducing dogs, and immediately reward your dog when they comply. Providing engaging toys or activities redirects their focus, reducing obsessive licking. Over time, consistent training fosters balanced, respectful dog-to-dog interactions.
Quick Answer: Obsessive licking is mostly a behavioural issue and is not harmful unless it causes skin damage or wounds on the licked dog.
Detailed Explanation: While obsessive licking rarely causes direct health issues, it can lead to stress, resentment, or even aggression if the licked dog becomes irritated. Owners should monitor interactions closely and prevent licking that causes discomfort. Ensuring all dogs are healthy and happy promotes a peaceful social environment.
Licking is rarely a dominance display in dogs. While early theories framed many canine behaviours through dominance hierarchies, modern animal behaviour research takes a different view. A dog licking another dog is far more likely to be communicating appeasement, friendliness, or submission than asserting control. The licking dog is essentially saying it poses no threat, which actually reduces social tension rather than escalating it. In multi-dog households, the dog doing the most licking is often the one seeking reassurance, not status. If you observe persistent or one-sided licking between dogs, the more useful lens is social dynamics and stress levels rather than dominance.
Face nibbling — sometimes called jaw sparring or muzzle mouthing — is a normal part of canine play and social bonding. Dogs use gentle nibbles to invite interaction, groom inaccessible spots around the ears and muzzle, and signal playfulness. It is distinct from licking: nibbling involves the front teeth in small, rapid movements rather than a full tongue sweep. Between well-bonded dogs it is a sign of comfort and trust. However, if the nibbled dog consistently tries to move away or shows tense body language, the behaviour has moved from mutual grooming into unwanted pestering, and a calm redirection is appropriate.
Eye licking is a grooming behaviour that dogs extend to animals they are close to, including their own puppies and trusted companions. The eyes and the area around them are difficult to self-groom, so allowing another dog to lick there signals a high level of trust. It is generally benign between healthy dogs. The concern arises when one dog licks the same spot repeatedly: constant moisture can cause skin irritation or introduce bacteria to the eye. If the licked dog has any discharge, redness, or appears to be squinting, it is worth a veterinary check to rule out an underlying infection that may be attracting the attention in the first place.
The idea that licking is primarily a submissive or dominance-related behaviour is largely a misunderstanding of canine communication. While licking can have a deferential component in certain contexts — a younger or lower-status dog may lick around the mouth of an older dog as an appeasement gesture — the behaviour has a range of motivations that have nothing to do with social hierarchy. Interpreting all licking through a dominance lens oversimplifies a nuanced communication system.
In multi-dog households, mutual licking is far more commonly an expression of social bonding and affiliative behaviour than a statement of rank. Dogs that are comfortable with each other engage in allogrooming — mutual licking and grooming — as part of their normal social repertoire. The context, body language of both dogs, and the response of the dog being licked give far more accurate information about the nature of the interaction than any assumption about dominance. A dog that licks another who is comfortable and relaxed in response is engaging in social bonding; a dog that licks one who is tense and trying to move away is creating conflict that needs management.
Licking is one of the first experiences a dog has in life — the mother's licking immediately after birth stimulates respiration, dries the puppy, removes the amniotic sac, and triggers elimination. This early experience establishes licking as intrinsically associated with warmth, safety, and care. Puppies quickly learn to lick back, licking around the mother's mouth as an appeasement signal and also, in wild canids, to stimulate regurgitation of food.
These early associations carry forward into adult social behaviour. Dogs that were well-socialised in early life and had positive licking experiences with their mother and littermates often show more affiliative licking behaviour as adults — it is a learnt social vocabulary. Dogs that were separated from the litter very early may lack normal social referencing and can develop either under- or over-reliance on licking as a communication tool. Understanding the developmental origins of licking helps contextualise why some dogs are enthusiastic lickers and others rarely engage in the behaviour.
