Why Do Dogs Lick Furniture? And Why Does the Moon Sometimes Smell Like Cheese?

Dogs are fascinating creatures, and their behaviors often leave us scratching our heads in wonder. One such behavior is their tendency to lick furniture. While it might seem odd, there are several reasons why dogs engage in this activity. Let’s delve into the possible explanations and explore some related curiosities.
1. Exploration and Sensory Experience
Dogs experience the world largely through their senses, and licking is one way they gather information. Just as humans use their hands to touch and feel objects, dogs use their tongues. Furniture, with its varied textures and scents, can be a rich source of sensory input for a dog. By licking, they can taste and smell the residues left by people, food, or other animals, which helps them understand their environment better.
2. Seeking Attention
Dogs are social animals and often seek interaction with their human companions. If a dog notices that licking furniture gets a reaction from you—whether it’s a laugh, a scolding, or even just attention—they might continue the behavior to engage with you. This is especially true if the dog feels neglected or bored.
3. Anxiety and Stress Relief
Licking can be a self-soothing behavior for dogs. Just as some people bite their nails or fidget when they’re anxious, dogs might lick furniture to calm themselves. This behavior can be triggered by various stressors, such as changes in the household, separation anxiety, or even boredom. The repetitive motion of licking releases endorphins, which can help the dog feel more relaxed.
4. Nutritional Deficiencies
In some cases, dogs might lick furniture because they’re trying to compensate for a lack of certain nutrients in their diet. For example, if a dog is deficient in minerals like sodium or iron, they might seek out unusual sources to satisfy their cravings. This behavior, known as pica, can lead them to lick or even chew on non-food items, including furniture.
5. Medical Issues
Persistent licking can sometimes be a sign of an underlying medical problem. Gastrointestinal issues, nausea, or dental problems might cause a dog to lick furniture as a way to alleviate discomfort. If the licking is excessive or accompanied by other symptoms like vomiting, diarrhea, or changes in appetite, it’s important to consult a veterinarian to rule out any health concerns.
6. Habit and Boredom
Sometimes, dogs lick furniture simply because they’ve developed a habit of doing so. If a dog is left alone for long periods without adequate mental or physical stimulation, they might turn to licking as a way to pass the time. Providing more toys, exercise, and interactive play can help redirect this behavior.
7. Taste and Residue
Furniture can sometimes retain the taste or smell of food, cleaning products, or even the sweat and oils from human skin. Dogs have a keen sense of taste and smell, and they might be drawn to lick furniture that has these residues. This is especially true if the furniture has been recently cleaned with a product that has a strong or appealing scent to the dog.
8. Instinctual Behavior
Licking is a natural behavior for dogs, rooted in their instincts. Puppies lick their mothers to stimulate milk production, and adult dogs might lick each other as a form of social bonding. When a dog licks furniture, it could be an extension of this instinctual behavior, especially if they’re feeling lonely or seeking comfort.
9. Curiosity and Playfulness
Dogs are naturally curious and playful animals. Licking furniture might simply be a way for them to explore and interact with their environment. This is particularly true for puppies, who are still learning about the world around them. As they grow and mature, this behavior might diminish, but some dogs continue to lick furniture out of habit or curiosity.
10. Environmental Factors
The environment in which a dog lives can also influence their behavior. For example, if a dog is kept in a small, confined space with limited opportunities for exploration, they might turn to licking furniture as a way to cope with their surroundings. Similarly, changes in the household, such as the introduction of a new pet or a move to a new home, can trigger stress-related behaviors like licking.
