Hello! Dogs may lick furniture because he’s bored. Lacking any other stimulation to engage his mind and body, he might just be trying to pass the time. If the behavior isn’t constant and if he’s easily distracted from it, try to make sure he has toys, games, and treats to occupy himself with when you’re not available.
Anxiety and stress can also result in obsessive licking and can be brought on by a change in the dog’s environment or routine. For example, is there someone new in the house, or a big uptick in activity? Dogs are creatures of habit and changes in their routine can make your dog anxious. Repetitive licking releases endorphins and is a way for dogs to self-soothe. In many cases, licking the sofa is an occasional response to occasional stress, loneliness, or boredom. However, it can become a habit if not checked.
Try adding more exercise, stimulation, and socialization to your dog’s life. Play more often; bring in new toys and challenging puzzles; arrange play dates; or take up a new activity like a dog sport. Exercise and activity are known stress relievers and, by the way, that works with humans, too. It’s the simplest remedy and there’s really no downside, even if it doesn’t solve the problem.
