Most dog owners think of their pets as harmless companions. But in NSW, one moment of unpredictability, a bark, a bite, a lunge, or a brief escape from the yard, can instantly escalate into:

• Criminal charges,
• Fines,
• Dangerous dog declarations,
• Destruction orders, and
• Heavy liability for injuries or property damage.

Every month, National Criminal Lawyers® represent owners whose dogs were involved in incidents ranging from minor nips in a park to serious attacks resulting in hospitalisation. Many owners are shocked to discover that councils routinely pursue criminal prosecutions, even when:

• The dog has no prior incidents;
• The injury was accidental;
• The dog was provoked;
• The owner acted responsibly; or
• The victim’s version is exaggerated or inconsistent.

This blog offers a comprehensive guide to dog attack offences in NSW:

• Your duties under the Companion Animals Act 1998,
• The meaning of a “serious” or “menacing” dog attack,
• Dangerous dog classifications,
• Criminal penalties,
• Breed-specific issues, and
• Defence strategies when Councils take you to court.

1. When Does a Dog Attack Become a Criminal Offence?

The relevant law is Section 16 of the Companion Animals Act 1998 (NSW).

Under s 16, a dog attack occurs when:

The dog rushes at, attacks, bites, harasses, or chases any person or animal (other than vermin).

Importantly:

• The dog does NOT need to bite for it to be considered an “attack”.
• Chasing, rushing or harassing can be enough.
• The victim’s fear is relevant, even without physical contact.

Dog owners face criminal liability even if the dog acted instinctively or unpredictably.

2. Penalties for Dog Attacks Under the Companion Animals Act

Penalties escalate depending on the severity.

Standard Dog Attack, s16(1)

Maximum penalties:

• $11,000 fine
• Civil liability for damage
• Control orders from the Council

Serious Dog Attack, s16(1A)

A “serious attack” involves:

• Significant injury,
• Hospitalisation,
• Disfigurement, or
• Severe injuries to other animals (e.g., pets killed).

Penalties dramatically increase:

• Up to $44,000 fine, AND
• Imprisonment up to 2 years (in the most serious cases), AND
• Destruction order for the dog.

Aggravated Offence, s16(2)

If the owner wilfully lets the dog roam, ignores warnings, or fails to fix a known problem (e.g., a broken fence), penalties increase.

3. Dangerous, Menacing & Restricted Dogs: What You Must Know

“Dangerous Dog” Declaration, s34

A Council may declare a dog “dangerous” if it:

• Attacks or kills an animal,
• Repeatedly threatens or rushes,
• Displays aggression without provocation.

Owners must then comply with strict rules:

• Special enclosure
• Warning signage
• Muzzling in public
• Restricted handling
• Specific collar
• Desexing

Failure to comply is a separate criminal offence.

“Menacing Dog” Declaration, s33A

A lower-level classification applied where a dog:

• Harassed,
• Chased, or
• Displayed aggressive behaviour

but without a serious attack.

Restricted Breeds, s55

In NSW, certain breeds are heavily regulated, including:

• American Pit Bull Terrier
• Japanese Tosa
• Dogo Argentino
• Fila Brasiliero
• Presa Canario

Restrictions include:

• Mandatory enclosure
• Muzzling
• Warning signs
• Neutering
• Strict control in public

Owners of restricted breeds are at increased risk of prosecution if their dog escapes or behaves aggressively.

4. How Dog Attack Cases Typically Arise

We see recurring patterns in real cases:

A. Dogs Escaping Through an Unsecured Fence

Even a small escape can result in:

• Fight with neighbour’s dog
• Attack on a cat
• Confrontation with a jogger

Council often charges the owner despite the dog’s lack of history.

B. Off-Leash Park Incidents

Owners assume off-leash rules offer protection, they do not.

If a dog:

• Snaps,
• Rushes,
• Jumps,
• Overwhelms a small dog, OR
• Causes a simple fall,

you may still be liable.

C. Delivery Driver Encounters

Couriers (Amazon, Australia Post, food delivery) file many complaints.
Even if a dog merely rushes toward the gate, this is often treated as an “attack”.

D. Neighbour Disputes

Often exaggerated due to existing tension.
Video footage and witness credibility become crucial.

5. Police vs Council: Who Charges You?

In most cases, local councils prosecute dog attack offences, not NSW Police.

Police tend to get involved when:

• A serious attack occurs,
• A criminal assault is alleged in addition, OR
• The dog is used as a weapon in a dispute.

Councils issue:

• Penalty notices,
• Court attendance notices,
• Dangerous dog notices,
• Destruction orders.

Many owners are unaware that Councils have significant prosecutorial power.

6. Defence Strategies Used by National Criminal Lawyers®

Our dog attack lawyers in NSW rely on several effective defences:

A. Dog Was Provoked

If the attack occurred because the victim:

• Entered your property unlawfully,
• Teased, hit or scared the dog,
• Aggressively approached the animal,

this may defeat the charge or significantly reduce penalty.

B. Victim Was Trespassing

If someone entered your premises without permission, this is a valid legal defence, especially under s16(3).

C. No Actual “Attack” Occurred

Where the dog did not make contact, only ran, barked or jumped, we argue the behaviour does not meet the statutory definition.

D. Dog Was Under Effective Control

If the owner was acting reasonably and within guidelines (e.g., leashed, enclosed), liability may be contested.

E. Procedural Errors by Council

We examine:

• Incorrect notices,
• Lack of evidence,
• Failure to identify the dog properly,
• Late service of documents.

Councils commonly make technical mistakes that lead to withdrawal.

F. Challenging Dangerous Dog Declarations

Using expert behaviour reports and cross-examination, we often overturn:

• Dangerous dog notices
• Menacing dog declarations
• Destruction orders

This is a critical part of animal-law defence.

8. What to Do Immediately After a Dog Incident

If your dog is involved in an incident:

Do:

Secure your dog immediately
Exchange details (like a car accident)
Photograph the area, injuries, fences
Collect witness details
Contact a lawyer before speaking to Council

Do NOT:

Apologise, it can be treated as an admission
Make statements to Council rangers
Sign dangerous dog declarations
Hand your dog over without legal advice
Assume the issue is “nothing serious”

Many cases escalate because owners panic or speak without advice.

Conclusion: One Incident Should Not Destroy Your Future or Your Dog’s Life

Dog attack allegations are serious, but they are also defendable. Councils often overcharge, misunderstand incidents, or push for unnecessarily harsh penalties, including destruction orders that can be challenged.

At National Criminal Lawyers®, we defend dog owners by:

• Challenging Council evidence,
• Negotiating to avoid convictions,
• Fighting dangerous dog declarations,
• Protecting your dog from destruction,
• Ensuring fairness and proper legal process.
