You've decided to welcome a puppy into the family. That's the exciting part. The harder part is working out where to buy one, and how to be sure the puppy you fall for hasn't come from a puppy farm.
This guide covers what a puppy farm is, the warning signs to look for, where these puppies tend to turn up for sale, and how the new NSW breeding laws help you check a seller before you hand over any money.
What a puppy farm actually is
The RSPCA defines a puppy farm (also called a puppy mill) as "an intensive dog breeding facility that is operated under inadequate conditions that fail to meet the dogs' behavioural, social and/or physiological needs".
In plain terms, it's a breeding operation that puts producing puppies ahead of the dogs' wellbeing. Most are large commercial setups, but size isn't the test. A small breeder with a handful of dogs can still fall well short on care. What matters is how the dogs live.
Common conditions inside a puppy farm
These are the conditions animal welfare groups see most often:
| Condition | What it looks like |
|---|---|
| Extreme confinement | Breeding dogs kept in cages or small pens with little or no exercise or socialisation |
| Poor vet and general care | Health problems left untreated, no regular checks, vaccinations skipped |
| Unhygienic living areas | Dirty bedding, waste build-up, no reliable clean water |
| Overcrowding | Too many dogs in too little space |
| Ongoing health and behaviour problems | Breeding dogs and puppies with chronic illness, fearfulness or anxiety |
Breeding mothers often have litter after litter with little recovery time in between. Puppies raised this way also miss out on the early handling and socialisation that helps them grow into confident, settled dogs.
Why it matters when you're buying a puppy
Puppies from poor breeding environments are more likely to come home with health problems like parasites, infections or inherited conditions. Many also struggle with behaviour issues, such as fear of people, other dogs or new places. That can mean vet bills, heartache and a lot of extra work in your first year together.
There's a bigger picture too. Every puppy bought from a puppy farm keeps that operation running, and the breeding dogs left behind are the ones who pay for it.
Where puppy farm puppies are sold
Puppy farm puppies can be sold almost anywhere: online classifieds and social media, newspaper ads, markets, car boot sales, poorly run pet shops, or straight from the farm itself.
You can't tell from the breed, either. Puppy farms breed whatever is in demand, from popular crossbreeds like cavoodles to purebreds. A sought-after breed and a high price tag are no guarantee of good breeding. The only reliable way to know how a puppy was raised is to see it for yourself.
What NSW law now requires of dog breeders
On 1 December 2025, NSW brought in tougher rules aimed at shutting down puppy farms. The key changes for buyers:
- Every dog breeder in NSW must hold a Breeder Identification Number (BIN) issued through the NSW Pet Registry. Rescue and rehoming groups use a Rehoming Organisation Number instead.
- Ads for dogs born on or after 1 December 2025 must show the dog's microchip number and the seller's BIN or rehoming number.
- A breeding property can keep no more than 20 undesexed adult female dogs, unless an exemption is granted.
- Female dogs are limited to five litters in their lifetime, and no more than three by caesarean.
- Breeders need at least one staff member for every 20 dogs.
For buyers, the BIN and microchip number are the useful ones. You can check both against the NSW Pet Registry before you commit. If an ad leaves them out, or the seller goes vague when you ask, treat that as a red flag.
How to avoid buying from a puppy farm
The new laws help, but your own checks still matter most. Before you buy:
- Visit in person. Ask to see where the puppies are raised and meet the mother. A responsible breeder or seller will welcome you. One who insists on meeting in a car park or delivering the puppy to you is a warning sign.
- Check the paperwork. Look for the microchip number, BIN, vaccination and worming records, and a recent vet check.
- Check the puppy's age. Puppies shouldn't leave their mother before 8 weeks old.
- Ask plenty of questions. Ask about health testing, temperament, socialisation, and what happens if things don't work out.
- Don't let anyone rush you. Pressure to pay a deposit on the spot, or lots of different breeds on offer at once, are both reasons to step back.
If something feels off, walk away. It's hard with a puppy in front of you, but the right one is worth waiting for.
Getting ready before your puppy comes home
Knowing what a puppy farm looks like is the first step to avoiding one. Visit in person, check the BIN and microchip number, and take your time.
If you're a first-time owner, our My First Puppy Workshops are a great place to start. They're a relaxed way to get your questions answered before you bring a puppy home. You're also welcome to drop into Kellyville Pets in Beaumont Hills for a chat with our dog team.
