Dogs lick human feet for a variety of reasons, all stemming from their natural instincts and behaviors. It's not always a simple answer, but rather a combination of factors.
Reasons for Foot-Licking
- Affection and Submission: Licking can be a canine way of showing affection and bonding. Just as they might lick your hands or face, your feet are accessible and become a target for their displays of love. [Reference: If your dog licks your feet, it could be their way of showing you that they care about you.]
- Taste and Smell: Human sweat contains salt and other substances that may pique a dog's interest. Their sense of smell is far superior to ours, and they might be investigating the unique scents on your feet. [Reference: Some here suggest the salt in the sweat and that would be the scientific answer.] They essentially have a "fine dining" experience. [Reference: Basically, when dogs lick your feet, they are enjoying a fine dining experience that elicits both taste and smell.]
- Information Gathering: Licking is a way for dogs to gather information about their environment and the people around them. Your feet provide a readily available source of data. [Reference: When dogs lick your feet or hands, it's because they're curious – they're trying to get more information from you.]
- Grooming Behavior: While it might seem strange to us, licking is a natural grooming behavior for dogs. They may be trying to clean your feet, particularly if they smell something interesting or unpleasant. This instinct can transfer from their pack grooming habits to their human companions. [Reference: Dogs just speak differently than we do, and licking is one of their ways of communicating and taking in their surroundings.]
- Attention-Seeking: Sometimes, a dog might lick your feet simply to get your attention. If you react to the licking (positive or negative), it reinforces the behavior. [Reference: Your dog licks you to show they care, to get attention, to understand you better and because they enjoy it.]
- Submissive Behavior: In some cases, licking feet can be a sign of submissive behavior. The dog might be attempting to appease you or show respect. [Reference: Licking feet is if anything a submissive gesture.]
It's important to note that licking, in most cases, is harmless. However, excessive licking could indicate underlying medical conditions or anxiety, and it's always best to consult a veterinarian if you're concerned.
