Is microchipping mandatory before selling a puppy in Australia?

Yes. Microchipping before the sale or transfer of a puppy (or any dog) is mandatory in all Australian states and territories. The specific legislative requirements vary by jurisdiction. In New South Wales, microchipping is required under the Companion Animals Act 1998 (NSW), and all dogs must be microchipped by 12 weeks of age (or before being sold or transferred if younger). The microchip must be implanted by a veterinarian or other authorised implanter, and the dog's details must be recorded on the NSW Companion Animals Register. In Victoria, microchipping is required under the Domestic Animals Act 1994 (VIC) before a dog is sold or given away. In Queensland, the Animal Management (Cats and Dogs) Act 2008 (Qld) requires dogs to be microchipped by 12 weeks of age. Similar obligations apply in South Australia under the Dog and Cat Management Act 1995 (SA), in Western Australia under the Dog Act 1976 (WA) as amended, and in all other states and territories. The 15-digit ISO-standard microchip number must be recorded in the Bill of Sale, and the buyer must update the microchip registration with the relevant state or territory companion animals register in their own name after the purchase is completed.

What is an ANKC registration number and what is the difference between the main register and limited register?

The Australian National Kennel Council (ANKC) is the peak body for purebred dog activities in Australia, and its member bodies in each state and territory (including Dogs NSW, Dogs Victoria, Dogs Queensland, CAWA in Western Australia, DAWA in Western Australia, Dogs SA, Dogs Tasmania, ACTCA, and Dogs NT) maintain a national register of purebred dogs. A dog registered with an ANKC member body is assigned a registration number and recorded on the national register, which confirms its breed lineage and entitles it to participate in conformation shows and other ANKC activities. There are two types of ANKC registration: the main register (also called full or unrestricted registration) and the limited register. A dog on the main register has no breeding restrictions and its offspring are eligible for registration. A dog on the limited register is registered but subject to breeding restrictions: it may not be used for breeding and its offspring will not be eligible for ANKC registration. Breeders often sell pet-quality puppies on the limited register to retain control over who breeds from their bloodlines. The register type must be clearly stated in the Bill of Sale. The Seller is responsible for transferring the ANKC registration papers (pedigree certificate) to the Buyer following the sale.

What are the laws about puppy sales from registered breeders in Australia?

The regulation of puppy sales and dog breeding in Australia is a matter primarily for state and territory governments, and the rules differ across jurisdictions. In New South Wales, the Companion Animals Act 1998 (NSW) requires that all dogs be microchipped before sale, and the NSW Government maintains a breeder identification system under which registered breeders hold a breeder identification number. In Victoria, the Domestic Animals Act 1994 (VIC) regulates dog breeders through a breeder source number system and imposes obligations on councils and breeders with respect to the registration of breeding operations, with the Victorian Government's domestic animal business registration applying to larger breeders. In Queensland, the responsible breeding policy (under the Animal Management (Cats and Dogs) Act 2008 (Qld)) imposes requirements on sellers of dogs (including microchipping, and disclosure of vaccination and health history). In South Australia, breeders with three or more breeding females must register as a commercial dog breeder. Breeders who are members of an ANKC-affiliated canine association are also subject to the codes of ethics and rules of those bodies, which typically impose minimum standards for health testing, veterinary care, and socialisation of puppies before sale.

Does the Australian Consumer Law apply to the sale of a puppy?

The Australian Consumer Law (ACL), which forms Schedule 2 to the Competition and Consumer Act 2010 (Cth), applies to the supply of goods in trade or commerce. Whether a puppy sale is covered by the ACL depends on whether the seller is acting in trade or commerce. A registered breeder who sells puppies on a commercial basis (even if small-scale) is likely to be acting in trade or commerce, and the puppy will be subject to the ACL's consumer guarantees, including the guarantee that the goods are of acceptable quality. A one-off private sale by an individual who is not in the business of selling dogs is less likely to be subject to the ACL consumer guarantees, although the ACL prohibition on misleading and deceptive conduct still applies to all persons. Where the ACL applies and a puppy is sold with a serious health defect that was known to the seller and not disclosed, the buyer may have a right to a remedy including a refund of the purchase price. It is therefore important for sellers to be honest about any health conditions or hereditary issues in the puppy, and for buyers to obtain a veterinary health check within 72 hours of purchase.

Is a desexing agreement legally enforceable in Australia?

A desexing agreement included as a condition of a puppy sale can be enforceable as a contractual term, but enforcement in practice can be challenging. Many ANKC-affiliated breeders include desexing clauses in their puppy contracts as a condition of selling on the limited register, requiring the buyer to have the puppy desexed by a specified age (typically four to six months) and to provide the seller with proof of the procedure (such as a veterinary desexing certificate). Breach of the desexing clause could entitle the seller to claim damages or, in appropriate cases, to demand the return of the puppy. Some states also have regulations that make desexing a default requirement for certain categories of animal: for example, in the Australian Capital Territory, all cats and dogs must be desexed unless the owner holds an entire animal licence under the Domestic Animals Act 2000 (ACT). In practice, many desexing agreements are enforced through the breeder's ability to cancel or restrict the ANKC registration of the dog, rather than through court proceedings.

Bill of Sale — Puppy (Australia) — Australia

Create an Australian Bill of Sale for the sale and transfer of ownership of a puppy. Covers mandatory microchip number, breeder identification number, ANKC registration and pedigree papers (main or limited register), vaccination status and certificate, veterinary health check, desexing agreement, council registration transfer, Companion Animals Act 1998 (NSW), Domestic Animals Act 1994 (VIC), GST treatment, and Australian Consumer Law. Suitable for registered breeders, hobbyist breeders, and private sellers across all Australian states and territories.

What Is a Bill of Sale — Puppy (Australia)?

An Australian Puppy Bill of Sale is a written legal document that records the sale and transfer of ownership of a puppy from a Seller (typically a breeder or private owner) to a Buyer. It captures all essential information about the transaction: the identities and addresses of both parties, the Seller's breeder identification number and ANKC registered prefix (if the Seller is a registered breeder), a full description of the puppy (including breed, sex, date of birth, colour, and the mandatory 15-digit ISO microchip number), ANKC or state canine association registration details and register type (main or limited), vaccination status and certificate details, veterinary health check information, any desexing agreement, the purchase price and GST treatment, and the moment at which title and risk pass from the Seller to the Buyer.

The sale of puppies in Australia is regulated by a patchwork of state and territory legislation governing companion animal registration, microchipping, breeder identification, and animal welfare. The key national legislative instruments are the Australian Consumer Law (Schedule 2 to the Competition and Consumer Act 2010 (Cth)), which applies mandatory consumer guarantees to commercial puppy sales, and the A New Tax System (Goods and Services Tax) Act 1999 (Cth) (GST Act), which may apply to sales by GST-registered breeders.

At the state and territory level, the Companion Animals Act 1998 (NSW) requires microchipping and registration of all dogs in New South Wales, and imposes obligations on breeders, councils, and buyers with respect to the transfer of microchip registration. The Domestic Animals Act 1994 (VIC) imposes equivalent obligations in Victoria, including a breeder source number system for dog breeders. Queensland's Animal Management (Cats and Dogs) Act 2008 (Qld), South Australia's Dog and Cat Management Act 1995 (SA), and Western Australia's Dog Act 1976 (WA) (as amended by the Cat Act 2011 (WA)) impose similar microchipping, registration, and breeder identification requirements in their respective jurisdictions.

When Do You Need a Bill of Sale — Puppy (Australia)?

An Australian Puppy Bill of Sale is needed whenever a puppy changes hands in Australia and the parties want a written record of the transaction, the health disclosures, and the transfer of ownership. The following are common situations where this document is important:

Registered ANKC breeder sales. When an ANKC-affiliated breeder sells a purebred puppy with pedigree papers, a Bill of Sale is important for recording the breeder's identification number, ANKC prefix, register type (main or limited), vaccination and health check details, and any desexing agreement that forms part of the Breeder's Code of Ethics obligations.

Hobbyist and small-scale breeder sales. When a hobbyist or small-scale breeder sells puppies from a planned litter, a Bill of Sale protects both parties by recording the key health disclosures (microchip number, vaccination status, health check), the agreed price, and the terms of the transfer.

Private sales. When an individual sells a puppy from an unplanned litter or re-homes a young dog, a Bill of Sale records the agreed terms and provides evidence of the transfer of ownership and microchip registration obligations.

Rescue and charity adoptions. While rescue organisations typically use adoption agreements rather than bills of sale, a written record of the transfer of ownership (including microchip number) is still important for companion animals legislation compliance.

Desexing agreements. Where the seller requires the buyer to desex the puppy as a condition of sale, a Bill of Sale is the appropriate document to record this contractual obligation and the buyer's agreement to comply.

What to Include in Your Bill of Sale — Puppy (Australia)

A well-drafted Australian Puppy Bill of Sale should include the following key elements to be legally effective and protect both parties:

Microchip number (mandatory). The 15-digit ISO-standard microchip number of the puppy must be recorded. Microchipping before sale is mandatory in all Australian states and territories, and the buyer must transfer the microchip registration into their own name after the purchase.

Breeder identification details. For registered breeders, the Bill of Sale should record the Seller's breeder identification number (as assigned by the relevant state or territory authority) and ANKC registered prefix (if any).

Puppy description. The breed, sex, date of birth, colour and markings, and name (registered and call name) of the puppy should be recorded to identify the animal beyond any reasonable doubt.

ANKC registration and register type. Where applicable, the ANKC registration number and whether the puppy is on the main register or limited register should be recorded. The main register / limited register distinction has significant implications for the buyer's ability to breed from the puppy.

Vaccination status and health check. The vaccination status at the time of sale (including the type and date of vaccination) and any veterinary health check details should be disclosed and recorded.

Desexing agreement. Where the seller requires desexing as a condition of sale, the required timeframe and the buyer's obligations should be clearly set out.

Purchase price and GST treatment. The price in AUD and the GST treatment (GST inclusive, not subject to GST) should be recorded.

Animal welfare obligations. The buyer's ongoing obligations as the responsible owner of the puppy under applicable companion animals and animal welfare legislation should be acknowledged.

Pet Care Agreement (Australia)

A Pet Care Agreement is a written contract between a professional pet care service provider and a pet owner (client) that sets out the terms and conditions for the provision of pet care, boarding, minding or related services in Australia. Whether the arrangement involves overnight boarding at the provider's premises, in-home pet minding, dog walking, day care, or a combination of services, a written agreement protects both parties, clarifies responsibilities, and ensures that the pet's welfare is properly managed during the care period. In Australia, professional pet care services are subject to the consumer guarantee provisions of the Australian Consumer Law (ACL), contained in Schedule 2 to the Competition and Consumer Act 2010 (Cth). The ACL applies to all services supplied in trade or commerce where the price of the services does not exceed $100,000 (or, in some circumstances, a higher threshold). Under the ACL, services must be provided with due care and skill, be reasonably fit for any particular purpose that the consumer makes known to the provider, and be supplied within a reasonable time if no time is agreed. These guarantees cannot be excluded, restricted or modified by contract in the case of a consumer. A well-drafted Pet Care Agreement acknowledges these statutory obligations and sets out how the parties will manage their relationship within that framework. Animal welfare legislation is also relevant. Each Australian state and territory has its own Prevention of Cruelty to Animals Act or equivalent — including the Prevention of Cruelty to Animals Act 1979 (NSW), the Prevention of Cruelty to Animals Act 1986 (Vic), the Animal Care and Protection Act 2001 (Qld), the Animal Welfare Act 2002 (WA), the Animal Welfare Act 1985 (SA), the Animal Welfare Act 1993 (Tas), the Animal Welfare Act 1992 (ACT) and the Animal Protection Act 2018 (NT). These Acts impose duties of care on anyone who is responsible for an animal, including a pet care provider during a boarding or minding engagement. A Pet Care Agreement should reflect the provider's commitment to comply with the applicable animal welfare legislation. Companion animal registration requirements must also be considered. In New South Wales, for example, dogs and cats over 12 weeks of age must be registered under the Companion Animals Act 1998 (NSW) and microchipped. Similar requirements apply in other jurisdictions. A Pet Care Agreement typically requires the owner to confirm that the pet is registered, microchipped and current on all required vaccinations — particularly for boarding providers who host multiple animals and need to manage disease risks. Vaccination requirements are critical for boarding facilities. Most professional boarding kennels and catteries require proof of current vaccination (at minimum C5 for dogs and F3 for cats in most jurisdictions) before accepting a pet. The Pet Care Agreement should include a vaccination warranty from the owner, specifying which vaccines must be current, the date of last vaccination, and the consequences — including refusal of service — if the vaccination records are not up to date. The agreement must include clear provisions for veterinary authority. The provider must have explicit written authority from the owner to seek emergency veterinary treatment if the pet becomes ill or is injured while in the provider's care and the owner cannot be contacted. The scope of that authority — including whether it covers all treatment or is subject to a cost cap — and the allocation of the resulting veterinary costs should be clearly documented. The fee structure, GST treatment (at 10% under the A New Tax System (Goods and Services Tax) Act 1999 (Cth) if the provider is registered for GST), payment terms and cancellation policy must also be addressed. Cancellation policies are a common source of disputes, particularly during busy holiday periods when boarding facilities are fully booked. Clear, written cancellation terms protect the provider's revenue and manage the owner's expectations. A Pet Care Agreement should also address the owner's representations about the pet's temperament, health, and behaviour — including any history of aggression towards people or other animals. If the pet injures another animal or person, or damages property, a signed representation by the owner about the pet's temperament is an important piece of evidence in any subsequent dispute about liability.
