Understanding Aggression
Aggression in Shih Tzus can be a serious issue, and it's essential to understand its underlying causes. If your Shih Tzu is biting aggressively, it's crucial to rule out physical pain as a cause, so a vet visit is the first step.
Aggressive biting is a sign of a deeper problem, and it's not just about punishing your dog for bad behavior. A professional like a Certified Applied Animal Behaviorist (CAAB or ACAAB) or a board-certified veterinary behaviorist (Dip ACBV) can help you identify the root cause of the aggression.
If you suspect your Shih Tzu is biting aggressively due to pain, a vet visit is a must. If the vet clears your dog of any physical issues, you'll need to consult a professional with expertise in treating aggression.
Causes of Aggression
Aggression in Shih Tzus can stem from physical pain, which is why it's essential to rule out any underlying medical issues with a vet.
If physical pain isn't the cause, a professional like a Certified Applied Animal Behaviorist (CAAB or ACAAB) or a board-certified veterinary behaviorist (Dip ACBV) should be consulted.
A Certified Professional Dog Trainer (CPDT) may also be helpful, but make sure they have a track record of successfully treating aggression.
A professional diagnosis is crucial in determining the root cause of aggression in your Shih Tzu.
Prevention and Training
To prevent your Shih Tzu from biting, it's essential to teach bite inhibition from an early age. Yelp in a loud, high-pitched voice that startles him, let your hand go limp and mimic being hurt, and yell a stern, "No bite!" if that doesn't work.
Make sure to praise your puppy when he stops biting and starts licking. This positive reinforcement will help him understand what behavior is expected. The ASPCA recommends doing this no more than three times within a 15-minute period.

If yelping doesn't work, you can try a time-out, which works better for adult dogs and older puppies. After trying the above method, ignore your dog for 10 to 20 seconds, get up and move away if he continues to try to play, or briefly leave the room if he is ignoring your cues.
Here's a step-by-step guide to help you train your Shih Tzu:
- Yelp in a loud, high-pitched voice to startle him.
- Let your hand go limp and mimic being hurt.
- Yell a stern, "No bite!" if that doesn't work.
- Praise your puppy when he stops biting and starts licking.
Remember to return to play after the time-out and keep playing until he bites again, then repeat the steps. With patience and consistency, you can help your Shih Tzu develop bite inhibition and curb aggressive behavior.
Shih Tzu Teething
Shih Tzu teething can be a challenging time for both you and your furry friend.
Shih Tzus may bite more frequently during teething, which can be due to the discomfort and pain they're experiencing.
Freezing special chew toys or giving your dog ice cubes to chew on can help dull some of the pain.
This behavior generally stops when teething stops, which should take about 10 months for all their adult teeth to come in.
Maintain a Routine

Maintaining a routine is crucial for your dog's well-being. Dogs thrive on predictability, and a regular routine helps them feel secure.
Provide opportunities for socialization at least a few times a week. This can be as simple as a walk around the block or a trip to the dog park.
Dogs that are isolated too often are prone to being fearful of others.
Use Positive Experiences
Using positive experiences is a great way to help your Shih Tzu feel more comfortable and secure. This can be achieved by exposing them to calm and well-behaved dogs and people.
Interacting with calm and well-behaved dogs and people can help your Shih Tzu learn good behavior and trust others.

Prevent Shih Tzu Biting
Preventing Shih Tzu biting requires a combination of understanding your dog's body language and teaching them bite inhibition. This is a normal part of play and exploration for most pups, but it's essential to learn the difference between play-biting and aggressive biting.
If your Shih Tzu is play-biting, look for relaxed body language, such as a loose jaw and wagging tail. Dogs that are aggressive will often appear stiff and may even show their teeth.
To teach your pup which types of bites hurt human skin and which don't, you can start by yelping in a loud, high-pitched voice when they bite too hard. Let your hand go limp and mimic being hurt, and if that doesn't work, yell a stern "No bite!" Make sure to praise your puppy when they stop biting and start licking.
Here are the steps to follow:
- Yelp in a loud, high-pitched voice that startles your Shih Tzu.
- Let your hand go limp and mimic being hurt.
- Yell a stern, "No bite!" if the first two steps don't work.
- Praise your puppy when they stop biting and start licking.
Remember to repeat these steps no more than three times within a 15-minute period, as recommended by the ASPCA. If yelping doesn't work, you can try a time-out, which works better for adult dogs and older puppies.
Managing Aggressive Behavior
If your Shih Tzu shows signs of aggression, it's essential to address the issue right away. Aggression can develop into more severe behavior if left unaddressed.
Socializing your puppy from an early age is critical in preventing aggressive behavior. This involves exposing your pup to various environments, people, and other animals to help them become confident and calm in new situations.
Watch for dominant behavior in your puppy, such as trying to nudge you out of your spot on the sofa or growling at you when you reach for a piece of dropped food. Discourage these actions immediately using positive reinforcement when training your dog.
Aggression can manifest in many forms, including fear, establishing dominance, nervousness, protecting territory or owner, sickness, pain, or confusion. Understanding the root cause of your pup's aggression is crucial in developing an effective plan to handle it.
If your usually calm and laid-back dog is suddenly acting aggressively, visit your vet for a health exam to rule out any underlying medical conditions or hidden injuries. This is the first step in determining the cause of your dog's undesirable behavior.
A visit to your vet or a professional trainer specializing in dog behavior can help uncover the root cause of your pup's aggression. They can work with you to develop a plan to address the issue and help your dog become a happier, more relaxed companion.
A different take: Dog Training Plan
Here are some common reasons why dogs display aggressive behavior:
• Frightened
• Establishing dominance
• Nervous
• Protecting their territory (or even their owner)
• Sick
• In pain
• Confused
If your dog has a history of aggression, it's crucial to consider who else lives in the home with the dog. If your dog has been re-trained, they may still not be a good fit for a home with young children or other dogs. Consult with your vet for an honest, unbiased, and realistic assessment of the ideal home for your canine pal.
