Dogs do not understand kisses the way humans do, as kissing is a purely human behavior not seen among dogs themselves. However, dogs can learn to associate kisses from their owners with positive feelings. This association often develops because kisses are typically paired with petting, a happy tone of voice, cuddles, or treats—all of which dogs do understand as signs of affection and happiness. Many dogs come to enjoy kisses because they connect them with the loving emotions and attention they receive from their humans. Signs that a dog enjoys kisses include relaxed body language, wagging tail, licking back, nuzzling, and seeking more attention. However, not all dogs like kisses; some may perceive the close facial approach as threatening and show signs of discomfort such as turning away, tense muscles, or even growling. So, while dogs don't innately know what kisses are, through experience and positive reinforcement, many dogs learn to recognize kisses as a friendly and affectionate gesture from their humans and respond positively to them. It is important to read your dog's body language and respect their individual preferences when it comes to kisses.
