Why Do Dogs Lick? (And Why They Won’t Stop)
Why your dog is obsessed with licking you (and your furniture).
If you’ve ever walked through the door after a long shift at work only to be greeted by a creature that wants to treat your face like a postage stamp, you’re not alone. According to global search data, “Why do dogs lick?” is the single most popular question humans ask Google about their pets.
Whether they’re licking your legs, your feet, or the sofa, there is a method to the madness. Here is the breakdown of why your dog is currently trying to marinate you in saliva.
1. The “I Love You” (Affection)
The most common reason is also the most sentimental. Licking is a natural instinct dogs inherited from their wolf ancestors. Mothers lick their puppies to groom them and show affection, and adult dogs continue this to strengthen their bond with you. It releases endorphins and dopamine in their brains, making them feel calm and happy.
2. You Taste Like a Snack
Let’s be honest: sometimes it isn’t love; it’s the salt. Human skin is covered in sweat, oils, and pheromones that are fascinating to a dog’s sense of smell, which is up to 100,000 times better than ours. Your feet, in particular, are like a detailed book for your dog, telling them exactly where you’ve been and what you’ve been doing.
3. The “Kiss to Dismiss” (Anxiety)
Sometimes, licking isn’t a greeting; it’s a request for space. Known by trainers as a “kiss to dismiss,” a dog might lick your face or hands if they are feeling anxious or crowded during a hug or play. If the licking is accompanied by lip-licking or looking away, your dog might be asking for a bit of room.
4. Seeking Information
When your dog licks you, they are essentially “smelling you with their mouth”. They use their tongue to gather sensory data about your mood and health. This is why they are particularly obsessed with licking legs and feet—it’s where the most interesting scent information lives.
FAQ
Why does my dog lick the air?
While it can look funny—like they’re daydreaming about ice cream—excessive air licking can sometimes be a sign of nausea or a gastrointestinal issue. If it’s constant, a quick trip to the vet is worth it.
Is it safe to let my dog lick my face?
While generally harmless, experts warn that dog mouths contain bacteria that can pose minor health risks. If you’ve just applied expensive moisturiser, maybe keep the tongue at bay for your skin’s sake.
Why do dogs lick the sofa or furniture?
This often stems from boredom or a self-soothing habit. Some dogs find the texture of fabric or metal interesting to taste, while others do it as a way to wind down after a busy day.
