Dog Licks Baseboards? Here's What to Do

Why Dogs Lick Baseboards

Dogs may lick baseboards for several reasons, including boredom, anxiety, or a need for mental stimulation. Like Max, a Gordon Setter who fixated on shadows and then licked the spot where they disappeared, some dogs develop compulsive behaviors tied to visual stimuli or repetitive actions. Licking can become a habit when it’s reinforced—either by the sensory feedback or by the attention it brings, even if negative. In some cases, such behaviors are linked to medical conditions, like hypothyroidism, which can worsen compulsive licking or chewing.

Manage the Environment to Stop Licking

To stop your dog from licking baseboards, first manage the environment. Just as a dog who chases shadows is kept out of the kitchen during meal prep, you can prevent access to the baseboards by using physical barriers. For example, place baby gates or use furniture to block the area. If the behavior persists, consider using a temporary cone (like the one used for Sadie) to stop the licking while you investigate the cause. However, avoid long-term use—most dogs dislike cones. Instead, focus on making the behavior unattractive or impossible to perform.

Redirect with Training and Positive Reinforcement

Redirect your dog’s attention to acceptable behaviors. When you catch your dog licking baseboards, calmly replace the behavior with a chew toy they’re allowed to use. Use a clicker and treats to reinforce the switch—click when they start chewing the toy, and reward immediately. Over time, they’ll learn to choose the toy over the baseboard. You can also teach a cue like “chew” or “toy” to signal the desired behavior. Practice in a controlled setting with tempting items nearby, then gradually increase difficulty.

Rule Out Medical Causes

Compulsive licking may be a sign of an underlying health issue. Sadie’s flank-sucking behavior improved only after a vet diagnosed her with hypothyroidism. Similarly, baseboard licking could be linked to hormonal imbalances, skin irritation, or anxiety disorders. A thorough medical check-up is essential before assuming the behavior is purely behavioral. If your dog is licking excessively, consult your veterinarian to rule out medical causes before starting training.

Increase Exercise and Mental Stimulation

Boredom and pent-up energy often drive destructive behaviors like licking. Just as Max’s environment was enriched to reduce fixation, your dog needs more mental and physical outlets. Increase daily walks, play sessions, and puzzle toys. A tired dog is less likely to engage in repetitive behaviors. Exercise helps reduce anxiety and gives your dog a healthy way to expend energy, making them less likely to focus on baseboards.
