When to Start Advertising Puppies for Sale (and How Early Is Too Early)
Breeding & Whelping
By James C. • November 9, 2026The best time to start advertising puppies is in two stages: announce a planned litter once the pregnancy is confirmed, then advertise individual puppies once they are born, microchipped and your ad carries the numbers your state requires.
Knowing when to start advertising puppies lets you build interest early without promising puppies that do not yet exist, and aim to confirm good homes before 8 weeks.
Below is a week-by-week timeline, the cut-off points that make an ad too early, a state-by-state summary of ad numbers and what to post at each age.
When Should You Start Advertising Puppies?
You should start promoting a litter once the pregnancy is confirmed, and start advertising individual puppies for sale once they are born and you can meet your state’s advertising rules.
Those are two different activities, and mixing them up causes most early-advertising problems.
Promoting a planned litter means telling people a litter is expected. You share the parents, the expected whelping date and how to join your waiting list. No individual puppy is offered, no price is binding and no deposit is taken.
Advertising puppies for sale means offering specific puppies to buyers. In most states that ad must include identification numbers, and in some states it must include each puppy’s microchip number, which means puppies must already be born and chipped.
Victoria spells this out clearly. Agriculture Victoria says ads for litters that are not yet available are exempt from showing microchip numbers, but must be updated with each animal’s microchip and the seller’s source number as soon as puppies become available.
That two-stage approach suits most breeders in every state. Early promotion fills your waiting list, while compliant individual ads convert interest into the right homes.
A Week-by-Week Advertising Timeline
A simple timeline is to promote from pregnancy confirmation, list individual puppies from around 4 to 5 weeks, and aim to confirm homes by 8 weeks.
| Stage | Advertising action |
|---|---|
| Before mating | Share planned pairing and health results with your waiting list only, no prices or deposits |
| Pregnancy confirmed (ultrasound around day 25 to 35) | Announce the expected litter and open waiting list applications |
| Birth | Share the arrival and litter size with your waiting list |
| 2 to 3 weeks | Send updates and begin screening applicants |
| 4 to 6 weeks | Microchip, then list individual puppies with photos, video and required numbers |
| 6 to 8 weeks | Match puppies to homes, share temperament notes, confirm pick-up dates |
| 8 weeks and beyond | Puppies go home; refresh any listing for puppies still available |
Ultrasound timing comes from veterinary guidance, with the MSD Veterinary Manual noting that pregnancy ultrasound is best performed at 25 to 35 days. Your vet will advise on the right timing for your dog.
The 8-week point matters because puppies cannot legally go home earlier in states such as NSW, and it is the age vets recommend as a minimum for the age puppies can safely leave their mother.
How Early Is Too Early?
An ad is too early when it offers something you cannot yet guarantee, and there are three clear cut-off points to watch.
Before the Pregnancy Is Confirmed
Before a vet confirms the pregnancy, share interest only. Mating does not guarantee a litter, so avoid prices, deposits or wording that suggests puppies are certain. A short waiting list note is enough.
Before the Puppies Are Born
Before birth, a waiting list is fine but binding deposits are not, because litter size and sexes are unknown. Watching for signs your dog is close to whelping helps you time announcements.
Before You Have the Numbers Your State Requires
Ads for actual puppies need identification numbers in most states. Missing numbers can breach state law, and they also look like a classic warning sign to buyers who know how buyers spot puppy scams.
What Your Puppy Ad Must Include by State
Most Australian states require a breeder or seller identification number in every puppy ad, and some also require each puppy’s microchip number.
| State | What the ad must show |
|---|---|
| NSW | Breeder identification number plus microchip number for puppies born from 1 December 2025 |
| VIC | Seller’s source number plus each puppy’s microchip number |
| QLD | Breeder supply number |
| SA | Dogs and Cats Online breeder registration number |
| WA, TAS, ACT, NT | Check current state or territory rules before advertising |
In NSW, the Office of Local Government confirms that ads for puppies born on or after 1 December 2025 must show a breeder identification number and the microchip number. Breeder association membership numbers are no longer accepted in their place.
Queensland requires a supply number on every dog ad, and buyers can check it on the Queensland Dog Breeder Register. In South Australia, councils advise that a breeder registration number must appear in all sale ads.
Rules change, so confirm the details for your state using these state-by-state breeding and advertising rules before you publish.
Using a Waiting List Instead of Early Ads
A waiting list lets you build demand before puppies are born without the risks of advertising puppies that do not exist yet.
Ask applicants about their home, routine, experience and why they want the breed. Screening early means you can match puppies to homes calmly once the litter arrives, rather than rushing at 7 weeks.
Good applicants will have questions of their own. Preparing answers to the questions buyers ask before paying a deposit makes conversations smoother and builds trust.
Take deposits only once puppies are born and healthy, and put the amount, balance due date and refund terms in writing. If the litter is smaller than expected, tell waiting list families promptly and refund in line with your written terms.
A waiting list also reduces how much open advertising you need. Many experienced breeders place most puppies with waiting list families and only list the remaining puppies publicly.
What to Post at Each Age
Post parent photos before birth, simple newborn updates, then individual photos and video from around 4 to 5 weeks when puppies’ looks and personalities start to show.
- Before birth: clear photos of both parents, health testing results and the expected whelping date.
- Birth to 3 weeks: litter photos and weight updates for your waiting list.
- 4 to 5 weeks: individual photos in natural light and short videos of play.
- 6 to 7 weeks: temperament notes, early training progress and vet check details.
Keep every photo honest and current. Buyers notice when listing photos show a younger puppy than the one they meet.
Where to Advertise Puppies in Australia
The best places to advertise puppies are dedicated puppy listing sites, breed clubs and your own network, rather than general social media marketplaces.
Dedicated listing sites put your puppies in front of buyers who are already searching. You can advertise your puppies on Pups4Sale with photos, inclusions and your state numbers, and choose from breeder listing plans that suit your litter size.
Breed clubs, your stud owner, your vet and previous buyers are also strong sources of good homes.
Social platforms have their own rules. The Oversight Board notes that Meta’s Commerce Policies prohibit animal sales on Marketplace, so check current platform policies before posting puppies anywhere on social media.
Wherever you advertise, never publish your home address. Share the suburb only, and give the full address once you have screened a buyer and booked a visit.
What If Puppies Are Not Reserved by 8 Weeks?
If puppies are not reserved by 8 weeks, refresh the listing, review the price fairly and keep socialising them until the right home is found.
New photos and video, honest temperament notes and a clear list of inclusions often bring fresh enquiries. Keep up vaccinations and gentle training, since a well-raised older puppy is still an excellent choice for many families.
Conclusion
Start early with litter announcements and a waiting list, then advertise individual puppies once they are born, chipped and your ad meets state rules.
Aim to confirm homes before 8 weeks, and keep caring for any puppy still available.
When your litter is ready, list your puppies with Pups4Sale and reach buyers across Australia.
Frequently Asked Questions
1. Can you advertise puppies before they are born?
You can announce an expected litter and open a waiting list before puppies are born, but you should not offer individual puppies or take binding deposits. Some states, such as Victoria, require ads to be updated with microchip numbers once puppies become available.
2. What age do you advertise puppies for sale?
Most breeders advertise individual puppies for sale from around 4 to 5 weeks, once puppies are microchipped and their looks and personalities are clearer. Before that, breeders usually share litter updates with their waiting list rather than placing public ads.
3. Do I need a breeder number to advertise puppies in Australia?
In most states, yes. NSW requires a breeder identification number, Victoria a source number, Queensland a supply number and South Australia a breeder registration number in puppy ads. Check your state or territory rules before you publish any listing.
4. Can I take a deposit before the puppies are born?
It is best not to take a deposit before puppies are born, because litter size and sexes are unknown. Keep a waiting list instead, then take a modest, receipted deposit once puppies are born and healthy, with refund terms in writing.
5. Can you advertise puppies on Facebook Marketplace?
Generally, no. Meta’s Commerce Policies prohibit animal sales on Marketplace, and listings that break the rules can be removed. Dedicated puppy listing sites, breed clubs and your own waiting list are more reliable ways to reach serious buyers.
6. How old must puppies be before they go to new homes?
Puppies should be at least 8 weeks old before they go to new homes, and this is a legal minimum in states such as NSW. Advertising earlier is fine, but pick-up dates should always fall at or after 8 weeks.
7. Does a puppy ad need to show the microchip number?
In some states, yes. Victoria requires each puppy’s microchip number in sale ads, and NSW requires it for puppies born from 1 December 2025. Other states focus on breeder numbers, so check your local rules before listing.
