Your dog licks your feet for reasons like affection, attention-seeking, grooming, or because they enjoy the salty taste and interesting scents (pheromones/sweat) that provide information about you and your day. It's a normal canine behavior, often stemming from pack instincts to care for and bond with their family, but excessive licking can signal anxiety or health issues.
Your dog licks you to show they care, to get attention, to understand you better and because they enjoy it.
If you are happy for your dog to lick your feet, there is no harm in them doing so. You shouldn't let your dog lick your feet if you have any open wounds.
Licking your feet can be a canine equivalent of grooming and a request for attention or closeness. Human sweat and skin secretions contain salts and amino acids that taste appealing to many dogs. Shoes pick up food particles, grease, and other flavorful residues, making them interesting to lick or chew.
Dogs' behavioral responses to their owners' hypoglycemic episodes varied. Most animals behaved in a manner suggestive of attracting their owners' attention, for example, vocalizing (61.5%), licking them (49.2%), nuzzling them (40.6%), jumping on top of them (30.4%), and/or staring intently at their faces (41.3%).
If the scent is detected by the dog, they then “alert” the person with diabetes, usually by touching them in a significant way such as pawing or nudging them. The handler then knows to check his or her blood sugar level. As a result, they may need to get something to eat or drink to prevent hypoglycemia.
Dogs say "sorry" through submissive body language like tucking their tail, lowering their head, making "puppy eyes," licking, and rolling onto their backs to show they're not a threat, which are appeasement signals to diffuse tension after a conflict or misbehavior, often combined with whining or approaching and retreating. They recognize when their human (or another dog) is upset and use these signs to seek forgiveness, though it's more about reducing stress than human-like guilt.
One of the most common reasons dogs give kisses is to express affection towards their loved ones. This licking behavior often begins in puppyhood, where it is a means for puppies to solicit attention from their mother.
Dogs lick their humans for all kinds of reasons including as a sign of affection or as a way of saying 'hello' or getting your attention. Licking can also occasionally be a sign that something is wrong.
Dogs often show affection by licking. It's an instinctive behaviour that's linked to the comfort they felt when their mother licked them as a puppy. Licking plays an important part of how they bond with others, causing them to release dopamine and endorphins that help make them feel relaxed, calm and happy.
To say "I love you" in dog language, use soft eye contact, raise your eyebrows, give gentle massages (especially ears), lean into them, and engage in play or shared activities like walks, which build trust and affection through shared experiences and physical connection, releasing oxytocin for both of you.
While licking you is a way for a dog to bond and promotes affection, stopping it will not compromise your relationship. Liza Cahn, a veterinarian at Embrace Pet Insurance, told Newsweek your pup may be persistent in trying to lick you but won't get offended if you take steps to prevent this.
Dog saliva and human saliva contain some ingredients that can help heal wounds. Wounds in the mouth tend to heal faster than those elsewhere in the body.
Your dog might be licking you because:
They're showing their affection, like when dogs groom each other or lick their friends faces. Maybe they're trying to avoid getting in trouble or saying they're sorry after they've done something bad, like when they get into the garbage and want to say sorry.
It's possible that your dog is detecting the scent changes associated with your athlete's foot condition, as dogs have a highly developed sense of smell. Dogs can identify subtle changes in scent. Your dog's sniffing is likely harmless curiosity. Contact with your athlete's foot poses minimal risk to your dog.
While healthy adults will almost certainly survive being exposed to the viruses or bacteria in their dogs' mouths, there is a non-zero risk of gastrointestinal illness and oral diseases from puppy kisses. Certain parasites like giardia, roundworms, and hookworms can also be transmitted through licks.
An hour for a dog feels much longer than an hour for a human because dogs perceive time more slowly due to their faster metabolism and heightened awareness of routines, so a 10-minute wait can feel like 70 minutes to them, and your hour-long absence feels like an eternity, though they don't grasp clock time but rather the intervals between events like meals, walks, and your return.
Signs Your Dog Loves You
Dog Breeds That Lick a Lot
A "mlem" in dogs (and other pets) refers to the cute, informal term for when their tongue sticks out, often just a little bit, as they lick their lips, nose, or mouth; it usually signals relaxation, contentment, or deep thought, though it can sometimes be a subtle sign of stress or a way to read human emotions, with a specific soft "melm" (tongue slightly in mouth) being very relaxed.
While dogs may not understand kisses in the way humans do, they can learn to associate them with positive emotions. Each dog is different, so it is essential to read their body language and respect their preferences to ensure they feel comfortable and loved.
How to spot the signs of stress
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
Generally, dogs dislike hugs, not being allowed to sniff, a lack of routine, and more. Even the most laid-back dog will hate some of the things we humans do—if they tolerate it, it's just because they love you or don't want to be dominant.
Leaning into you
Leaning against your leg (or whatever part is closest to them) is a big sign that they love you. If you find your dog leaning against you, take a moment to pet him and show him some extra affection.
