"I've just reserved a puppy and the breeder has said I can collect him in two weeks, when he'll be six weeks old. That feels quite young to me – is it too soon to take him away from his mum? What age should a puppy be before they leave their mother, and what should I look out for when I go to collect him?"
In short, puppies can leave their mother from eight weeks old.
What does the law say?
The short answer is no. In England and Wales, it’s illegal to sell or give away a puppy under eight weeks of age. This applies to breeders, rescue centres, and private sellers alike.
Under Lucy’s Law, introduced in April 2020, puppies can only be sold directly by the breeder – not through third-party dealers or pet shops. Licensed breeders need to show the puppy with their mother at the place of birth. If a breeder is unwilling to do this, you can consider this a major red flag.
Why does eight weeks matter?
The first eight weeks of a puppy’s life are critical for their development. This is when they learn how to interact with other dogs, manage their own behaviour, and begin to understand the world around them – all through their mother and siblings.
A puppy’s socialisation window begins at around four weeks old. So, taking them away from their mother before the end of this period isn’t a good idea. It cuts short their learning at a crucial stage.
Puppies who leave too soon are more likely to develop fear, anxiety, and behavioural problems later in life. These issues can be difficult to tackle and they’re one of the most common reasons dogs end up in rescue centres.
Is earlier than eight weeks ever acceptable?
In most cases, no. Some people believe that once a puppy is weaned off milk – which can happen from around six weeks – they’re ready to leave. But this is a common misconception.
Weaning and readiness to leave the litter are not the same thing. Those extra weeks spent with their mother and siblings are about much more than food.
If someone offers you a puppy younger than eight weeks old, they’re breaking the law. Even if the situation seems genuine or the puppy appears healthy, buying from that person funds poor breeding practices. It also puts the puppy’s long-term welfare at risk.
Could waiting even longer be better?
Eight weeks is the legal minimum, but many vets and welfare organisations suggest that waiting until ten to twelve weeks. This can benefit some puppies, especially those who are smaller, less confident, or from larger litters.
Around this age, puppies are often better settled, more resilient, and easier to transition into a new home.
Talk to your breeder about what they feel is right for the specific litter.
What to look for when you collect your puppy
Here’s a handy checklist to go through before bringing home your new canine companion:
- The puppy is at least eight weeks old and they’ve been microchipped.
- You’ve seen the puppy with their mother in the place where they were bred.
- The puppy is alert, curious, and moving freely – not lethargic or visibly unwell.
- The mother appears calm and in good health. Her behaviour gives you a strong indication of how the puppy may develop.
- The breeder can provide vaccination records and has used a Puppy Contract or similar documentation.
