The Yuen Long YOHO Dog Attack: What Happened and How We Can Help Keep Dogs and People Safe
Learn why leashes, recall training, respecting other dogs' space, and knowing how to respond safely can help prevent another tragedy.
How to Prevent and Respond to a Serious Dog Attack
A serious dog attack occurred at Yuen Long YOHO on August 17, in which two small dogs—a brown Miniature Poodle and a white Bichon Frise—were reportedly fatally attacked by a much larger dog.
Witnesses reported that the large dog was not successfully restrained during the incident, while members of the public attempted to help. The tragedy has understandably left the affected families, witnesses, and wider community deeply distressed.
Our hearts go out to the families who lost their beloved companions. For many people, a dog is not simply a pet, but a cherished member of the family. Losing a companion in such a sudden and traumatic way can be devastating.
While the circumstances of this particular incident remain subject to investigation, it is also an opportunity for all of us to think about how we can reduce the risk of similar tragedies.
The most important principle:
Protect people first, avoid direct physical intervention whenever possible, and focus on preventing a dog fight before it starts.
The following guidance brings together commonly recommended approaches from animal welfare and veterinary organizations. It is intended for general education and should not replace professional advice or local regulations.
1. Prevent the conflict whenever possible
Once two dogs are actively fighting, separating them can be extremely dangerous. People who try to intervene physically can suffer serious bite injuries, including from their own dog through redirected aggression.
Whenever possible, recognize warning signs early and create distance before the situation escalates.
Signs that a dog may be becoming uncomfortable or highly aroused can include:
- Stiffening or freezing of the body
- Intense staring
- Raised hackles
- Growling or showing teeth
- Lunging or barking
- Attempting to escape or hide
- Repeatedly trying to approach another dog despite being restrained
If you notice these signs, increase distance rather than forcing the dogs to interact.
Cross the street, change direction, move behind a barrier, or calmly leave the area if necessary. Sometimes the best intervention is simply getting your dog away before anything happens.
2. If a dog fight breaks out, prioritize human safety
If two dogs are already fighting, the first instinct of many people is to grab a collar, pull a dog away, or reach for its mouth.
Unfortunately, this can result in severe injuries. A highly aroused dog may bite whatever is closest to it, including a person trying to help. This is sometimes referred to as redirected aggression.
Try non-contact methods first
If it can be done from a safe distance, possible options include:
- Create a physical barrier: Use a door, gate, large piece of furniture, board, or other sturdy object to separate the dogs.
- Use water: A hose or container of water may sometimes interrupt the interaction.
- Use a sudden sound: A whistle or other unexpected sound may distract the dogs in some situations.
- Use a blanket or large towel as a visual barrier: If it can be placed without approaching the dogs, temporarily blocking their view of one another may help interrupt the interaction.
These techniques are not guaranteed to work, and you should never move closer simply to try one of them.
The priority is always to avoid becoming another victim.
3. What not to do
Do not put your hands between fighting dogs
Never place your hands near the dogs’ mouths or attempt to physically pry their jaws apart.
Do not grab collars with your bare hands
A dog can turn and bite the person holding its collar, even if it normally knows and trusts that person.
Do not put your face near the dogs
In the panic of an emergency, people sometimes instinctively bend down or reach toward the animals. This can result in catastrophic facial injuries.
Avoid kicking or repeatedly hitting the dogs
Physical punishment can increase arousal and make the situation more chaotic. It can also put you within biting range.
Be cautious about physically separating dogs
Techniques such as lifting the hind legs, sometimes called “wheelbarrowing,” have been described as ways of separating fighting dogs. However, they still require a person to approach an actively fighting animal and therefore carry a significant risk of injury.
They should not be treated as a routine technique for members of the public.
If there is a safe alternative, use distance and barriers instead.
4. Once the dogs are separated
The danger is not necessarily over when the dogs stop fighting.
Create physical separation immediately
Use a closed door, gate, vehicle, fence, or other secure barrier to keep the dogs apart. Do not allow them to immediately approach each other again.
A dog may remain highly aroused for some time after an altercation, and another encounter can trigger renewed aggression.
Check people first
Anyone who has been bitten or scratched should receive appropriate medical attention. Dog bites can cause significant tissue damage and infection even when the wound appears small.
Check the dogs
Dogs can sustain serious injuries that are not immediately obvious, particularly puncture wounds underneath fur.
Veterinary examination is advisable following a significant fight, especially when:
- There are puncture wounds
- There is bleeding
- The dog is limping
- The dog seems weak, painful, or unusually quiet
- There is difficulty breathing
- The bite involved the chest, abdomen, neck, or eyes
- A large dog has attacked a small dog
When in doubt, have the dog assessed by a veterinarian.
5. Why keeping your dog on a leash in public matters 
One of the simplest ways to reduce the risk of a serious incident is also one of the most important:
Keep your dog appropriately restrained in public spaces, according to local laws and the rules of the location.
Some owners may think, “My dog is friendly. He would never hurt anyone.”
That may very well be true. But a leash is not only about preventing your dog from attacking someone. It also protects your dog from unpredictable situations.
Even a friendly, well-behaved dog can suddenly:
- Run into traffic after becoming frightened
- Chase a cyclist, runner, child, or another animal
- Approach a dog that does not want to interact
- Become frightened by a loud noise and bolt
- React defensively when another dog approaches too quickly
- Become involved in a fight between other dogs
- Run away after being startled
Dogs do not always behave exactly as they do at home. A familiar dog can behave very differently when exposed to crowded environments, unfamiliar people, strange dogs, traffic, loud noises, or other stressful stimuli.
A leash also protects other dogs
This is particularly important when walking a small, elderly, anxious, injured, or reactive dog.
A large, friendly dog running toward another dog may be trying to play—but the other dog may perceive that approach as threatening.
Not every dog wants to say hello.
Giving other dogs space is one of the simplest ways we can show consideration to fellow dog owners.
6. When is it appropriate to let your dog off leash?
Off-leash freedom can be wonderful for dogs. Running, exploring, sniffing, and playing can all contribute to physical and mental well-being.
But freedom should come with responsibility. Before letting a dog off leash, consider both the law and the environment.
Generally, off-leash exercise is most appropriate when:
- The location legally permits dogs to be off leash
- The area is securely fenced or designed for off-leash activity
- Your dog has a reliable recall and returns promptly when called
- Your dog remains under control around other dogs and people
- Your dog does not have uncontrolled chasing or aggressive behavior
- The environment is appropriate and free from obvious hazards
- You can supervise your dog continuously
- You can safely put the leash back on when necessary
A dog being “friendly” is not enough. A dog being “well trained” is not enough. Being able to recall your dog reliably in a quiet park does not necessarily mean you can recall the dog when it is excited, frightened, chasing something, or surrounded by unfamiliar dogs.
If your dog’s recall is still developing, consider using a long line in an appropriate safe area while continuing training, rather than taking unnecessary risks.
Most importantly, always follow the leash requirements of the local authority and the specific area.
Off-leash freedom should be earned through training and provided in an appropriate environment—not assumed simply because a dog is friendly.
7. Responsible dog ownership is about more than controlling your own dog
Being a responsible dog owner does not mean expecting every dog to behave perfectly. It means recognizing that we cannot control everything around us, but we can control how responsibly we manage our own dogs.
That includes:
- Keeping dogs appropriately leashed in public areas
- Training a reliable recall
- Learning to recognize canine stress and warning signals
- Giving unfamiliar dogs adequate space
- Avoiding forced interactions
- Supervising dogs rather than relying on assumptions
- Knowing local leash and animal-control regulations
- Seeking professional help when a dog shows aggression or serious reactivity
Other people may have very different dogs and circumstances.
- A small dog may be elderly.
- A dog may be recovering from surgery.
- A rescue dog may be frightened of unfamiliar dogs.
- A child may be afraid of dogs.
- A service or assistance dog may need to remain focused on its handler.
Keeping our dogs under control is not just about our own pets. It is an act of consideration toward everyone sharing the same public space.
8. A final reminder
Dog attacks can happen very quickly, and once a serious fight begins, even experienced people may find it difficult and dangerous to intervene.
The best strategy is therefore not to become better at breaking up dog fights. It is to reduce the chance that a fight happens in the first place.
Keep your dog under control. Give other dogs space. Learn your dog’s body language. Respect local leash rules. And never assume that because a dog has always been friendly, it can never react unexpectedly.
Every dog deserves to feel safe. Every owner deserves to walk their dog without fear. And every community benefits when we look after not only our own dogs, but also the dogs and people around us.
Quick checklist: What to do during a dog attack
If a dog is biting another dog
- Keep yourself out of biting range. Do not grab collars, reach into the dogs’ mouths, or stand between them.
- Call for help. Ask someone to contact emergency services while you look for a safe way to create distance.
- Use a barrier first. Place a door, gate, chair, board, car door, or rubbish-bin lid between the dogs.
- Try water or a sudden sound. A hose, bucket of water, whistle, or alarm may briefly interrupt the attack.
- Separate the dogs completely. Move one dog behind a closed door, gate, vehicle, or fence. Do not let them approach each other again.
- Check people before animals. Anyone bitten or scratched should receive medical attention.
- Take the injured dog to a veterinarian. Small punctures can hide serious tissue damage or infection.
If a dog is biting a person
- Call emergency services immediately. In Hong Kong, call 999 if the attack is ongoing or someone is seriously injured.
- Do not pull the victim away with your hands. This may cause the dog to bite harder or redirect its attack toward you.
- Use a barrier from a safe position. A gate, chair, door, board, or vehicle may help block the dog.
- Do not put your face or hands near the dog. Avoid kicking, punching, or trying to open its jaws.
- Once the dog releases, create distance quickly. Secure the dog behind a closed barrier if this can be done safely.
- Seek medical care for every bite. Wash the wound with soap and running water, then obtain professional medical attention.
- Record key details if safe. Note the location, time, dog’s appearance, owner’s details, and direction of travel for authorities.
Remember: The safest intervention is usually distance, barriers, and professional help—not physical restraint.
Frequently asked questions
What should I do if a dog is biting another dog?
Keep your hands and face away from the dogs. Use a sturdy barrier, water, or a sudden sound from a safe distance, then separate the dogs behind a closed door, gate, fence, or vehicle. Seek veterinary care for the injured dog, even if the wounds look small.
Should I pull a dog away by its collar?
No. Pulling a collar during an active fight can place your hands within biting range and may trigger redirected aggression. Try creating distance with a barrier instead. If the attack continues, call for professional emergency assistance rather than risking serious injury.
What should I do if a dog is biting a person?
Call emergency services immediately if the attack is ongoing or the person is seriously injured. Do not pull the victim away with your bare hands. Use a barrier from a safe distance, such as a gate, chair, door, board, or vehicle, if you can do so safely.
Should I see a doctor after a dog bite?
Yes. Wash the wound thoroughly with soap and running water, then seek medical attention. Dog bites can damage deeper tissue and introduce bacteria, even when the puncture appears small. Medical professionals can assess infection, tetanus protection, and other risks.
Does a dog need a veterinarian after being attacked?
Yes, particularly if the dog has puncture wounds, bleeding, limping, weakness, breathing difficulty, or bites around the chest, abdomen, neck, or eyes. Injuries hidden beneath fur can be more serious than they first appear.
Can I use the wheelbarrow method to separate fighting dogs?
The wheelbarrow method carries a significant bite risk and should not be treated as a routine technique for the public. It requires two adults and still involves approaching actively fighting dogs. Use distance, barriers, water, or professional help whenever possible.
How can I prevent my dog from becoming involved in a fight?
Keep your dog appropriately leashed in public, watch for stiff body language, staring, growling, lunging, or attempts to escape, and create distance early. Avoid forced greetings and respect dogs that need extra space because they are nervous, elderly, injured, or reactive.
When can I let my dog off leash?
Only use off-leash areas where local rules permit it and where your dog can be supervised safely. Your dog should have a reliable recall, remain under control around people and dogs, and return promptly even when distracted or frightened. A friendly temperament alone is not enough.
Responsible handling is not about restricting our dogs—it is about giving them the freedom to enjoy the world as safely as possible.
