Why Shih Tzus Lick So Much: 7 Common Reasons (and When to Worry)

If you live with a Shih Tzu, you’ve probably accepted that your dog’s love language might be… licking. Hands, faces, blankets, the couch—sometimes even the air. Shih Tzus lick so much for a mix of sweet, silly, and occasionally concerning reasons.

1) Affection and bonding (the classic Shih Tzu “kiss”)

One of the biggest reasons Shih Tzus lick so much is simple: they adore you. Licking is a social behavior dogs learn early, and it can be a way of saying, “You’re my person, I feel safe with you.”

Shih Tzus were bred to be companion dogs, so closeness is kind of their whole thing. If your dog climbs into your lap and starts licking your fingers like they’re checking in, that’s often bonding in real time.

2) Attention-seeking (because it works)

Most pet owners don’t realize how quickly dogs connect actions with outcomes. If licking makes you laugh, talk to them, pet them, or even gently push them away while making eye contact, your Shih Tzu may file that under: “Success.”

Over time, the licking becomes a habit because it reliably gets a response. Even “Stop it!” can feel rewarding if what your dog wanted was your attention.

3) Exploring the world through taste and smell

Dogs don’t experience the world the way we do. Your skin carries scents, traces of whatever you touched, and tiny hints of your environment—basically a whole news feed for your dog.

Licking is one way Shih Tzus gather information up close. If you’ve ever come home and your dog immediately starts licking your hands or ankles, they may be “reading” where you’ve been.

4) Self-soothing when they feel stressed or anxious

Shih Tzus lick so much sometimes because it helps them calm down. Repetitive behaviors can be soothing for dogs, especially during stress, loneliness, or changes in routine.

If you notice licking ramps up during thunderstorms, when guests arrive, after you leave the house, or at bedtime, it may be your dog’s way of regulating their emotions. It can look affectionate, but the timing and intensity often tell the real story.

5) Boredom and lack of mental stimulation

Shih Tzus are small, but they still need daily interaction and things to do. Without enough enrichment, licking can become a “filler activity”—something to pass the time and release pent-up energy.

If your dog spends long stretches awake with little engagement, you might see more licking of blankets, cushions, or their own paws. Short play sessions, simple training games, and puzzle toys can make a noticeable difference.

6) Normal grooming (but watch for patterns)

Some licking is just hygiene. Dogs groom themselves, and some will gently groom their people or other pets too.

The key is whether it’s occasional and casual, or repetitive and targeted. If your Shih Tzu keeps licking the same paw, the same patch of skin, or the same spot on their body for long periods, that’s less “grooming” and more “something is bothering me.”

7) Discomfort or health issues (the reason you shouldn’t ignore)

Sometimes excessive licking is your dog trying to deal with a problem. Common triggers include:

• Skin irritation or allergies
• Pain or inflammation (especially if licking focuses on one area)
• Digestive discomfort (some dogs lick surfaces more when nauseous)
• Parasites or infections
• Anxiety that’s tipping into compulsive behavior

If your Shih Tzu’s licking becomes obsessive, causes redness or hair loss, interrupts sleep, or seems impossible to redirect, it’s worth getting them checked out.

How to tell what your Shih Tzu’s licking means

Context is everything. Ask yourself:

• When does the licking happen—during cuddles, after you come home, or during stressful moments?
• Where is your dog licking—your hands and face, random objects, or one specific body spot?
• How intense is it—quick “kisses” or long, repetitive sessions?

If you’ve ever noticed your Shih Tzu licking more on days you’re busy or out of the house, that’s a strong clue the behavior is meeting an emotional need, not just showing affection.

A simple takeaway

Shih Tzus lick so much because it’s one of their favorite ways to connect, communicate, and cope. Most of the time it’s normal—just your little companion being extra. But if the licking becomes constant, focused, or frantic, treat it like a message your dog really needs you to hear.
