If your Shih Tzu bites your hand, it can be confusing and frustrating—especially for new owners. The good news is that most biting behavior in Shih Tzus is normal and fixable, especially in puppies.
Understanding why your dog is biting is the first step to correcting the behavior safely and effectively.
Common Reasons Why Shih Tzus Bite
1. Teething (Most Common in Puppies)
Shih Tzu puppies go through a teething phase where they chew and bite to relieve discomfort.
Signs:
- Chewing everything
- Mild biting during play
- Irritated gums
2. Playful Behavior
Dogs often use their mouths during play. Your Shih Tzu may not realize that biting your hand is not acceptable.
Signs:
- Tail wagging
- Excited energy
- Gentle nipping
3. Attention-Seeking
Your dog may bite to get your attention, especially if they are bored or ignored.
4. Fear or Anxiety
If your Shih Tzu feels threatened, they may bite as a defense mechanism.
Signs:
- Growling
- Backing away
- Tense body posture
5. Lack of Training
Without proper training, dogs don’t understand boundaries and may continue biting behavior.
How to Stop Your Shih Tzu from Biting
1. Teach Bite Inhibition
When your puppy bites too hard:
- Say “No” or “Ouch” calmly
- Stop playing immediately
- Ignore your dog for a few seconds
This teaches your Shih Tzu that biting ends fun.
2. Redirect to Toys
Always replace your hand with a chew toy.
- Give a toy when your dog starts biting
- Praise when they chew the toy instead
3. Avoid Rough Play
Games like wrestling or hand play can encourage biting.
Instead, use:
- Toys
- Balls
- Tug ropes
4. Use Positive Reinforcement
Reward good behavior:
- Treats
- Praise
- Gentle petting
Your dog will learn what behavior is acceptable.
5. Stay Consistent
Consistency is key.
- Use the same commands
- Correct behavior every time
- Ensure all family members follow the same rules
6. Provide Enough Exercise
A tired dog is less likely to bite.
- Daily walks
- Playtime
- Mental stimulation (puzzle toys)
When to Be Concerned
Seek help from a professional trainer or veterinarian if:
- Biting becomes aggressive
- Your dog shows fear-based behavior
- Bites cause injury
- Behavior does not improve with training
