Why should you wait until 8 weeks to bring your puppy home?
Bringing your puppy home at 8 weeks, rather than earlier, gives them vital time with their mother and littermates to develop behaviourally and physically. During this window, puppies learn bite inhibition, build confidence and complete an important stage of gut microbiome development, all of which shape how well-adjusted they’ll be in their new home. This article explains what the research shows and what to look for in an ethical, reputable breeder.
Bringing a puppy home is an exciting time. You have done your research, selected a breed and a reputable breeder and bought the necessary supplies such as beds, toys and food. Now, you just need to wait until the puppy reaches the appropriate age to join your family. While the wait can sometimes feel lengthy, many are tempted to bring their new puppy home earlier. However, those additional weeks spent at the breeder’s home with their mother and littermates can be highly beneficial for the puppy’s behavioural and health development. We will explore why 8 weeks is the recommended age for welcoming your new puppy into your home.
A puppy’s socialisation period generally spans from approximately 3 weeks to 14-16 weeks of age.
What do puppies learn from their mother and littermates?
Being with the mother and littermates as they mature offers numerous behavioural benefits.
Puppies learn bite inhibition through play with their littermates. During play, puppies bite each other and if someone bites too hard, they receive feedback indicating that the bite was too strong. This helps teach them to play with a gentler bite. Such feedback is essential to ensure your puppy does not develop a hard bite when playing.
Additionally, they learn to interpret other dogs’ body language and develop social skills for interacting with their peers. They also learn to disengage from overly vigorous play and build frustration tolerance. All of these skills develop naturally within a typical social group of littermates and a mother overseeing interactions.
Removing puppies from the litter at an early age can hinder their ability to develop these important social behaviours. Confidence is also built at this early stage. Pups can interact with novelty but have the safety net of their siblings and mother to retreat to if they get startled. This develops resilience to stress, as they can recover quickly and then continue to explore.
Research has shown other behaviour issues can develop from early separation from mother and littermates.
Pierantoni, Albertini & Pirrone (2011) compared dogs that left the litter around 4–6 weeks with those that stayed until closer to 8 weeks. Owners of the earlier, separated dogs reported a noticeably higher rate of problem behaviours, including destructiveness, excessive barking, possessiveness over items and fear-related behaviours such as nervousness on walks and sensitivity to noise. It is possible that less stress and frustration tolerance shows itself as ‘problematic’ behaviours in pups.
From a medical perspective, the stress of leaving the litter early, before they are developmentally ready, may contribute to health problems. Early life is an important stage of gut microbiome development. Stress associated with early rehoming, or a rushed weaning process, can be linked with digestive disturbances, particularly during the high-risk weaning period.
The potential medical and behavioural risks can create a real financial burden for the new puppy owner. Puppies that leave their litter early are more likely to need extra support. Frequent vet visits to address medical issues such as diarrhoea, inadequate weight gain, or stress-related illnesses.
Or consultations with an animal behaviourist may be necessary to navigate mouthing and poor impulse control, for instance. This experience can also take a significant emotional toll on the owner.
In some situations, early removal from the litter may be appropriate.
There is substantial research indicating that puppies in poor breeding conditions, such as those from unscrupulous facilities, lacking socialization, or in barren or unhygienic environments, may need to be removed sooner rather than later.
Risks may include the potential for disease or, in some cases, harm from adult dogs in the household.
If a puppy is in an environment that could negatively impact its development, it should be relocated as soon as it is safe to do so. When a setting is harmful, transferring the puppy to a safer environment at an earlier stage may be in its best interest. If this does happen, that pup will need additional behaviour and medical support to help them become a well-adjusted pup.
While removing the puppy promptly may seem like the right course of action, purchasing a puppy from such breeders can inadvertently sustain their practices by providing them with financial incentive. Instead, it is advisable to report these cases to the SPCA or relevant authorities to help ensure that appropriate action is taken to prevent such situations in the future.
Unfortunately, there are breeders out there that actively encourage pet parents to take the pup home as early as possible.
How do you know if a breeder is reputable?
People are often unsuspecting and collect the pup as they trust the breeder that the puppy is ready for their new home. If the breeder is pressuring you to collect the pup before 8 weeks, you should definitely take a closer look at where you are buying the pup from and question whether they are an ethical breeder.
Take a step back and take a closer look at their rearing practices.
Find out their plans for socialisation while the pup is with them and check the living conditions to ensure you are collecting the pup from somewhere reputable. The environment should be clean, safe and enriched. The mother should also be healthy and pups and mum should be living in a home environment ready for the transition into your home.
Bringing a puppy home is hopefully the start of a long and wonderful relationship. It is natural to want to get the puppy home as soon as possible, but waiting until they are at least 8 weeks old increases the chances of the adoption being successful. A reputable breeder won’t rush the process. They will want their pups to have the best chances of success in their new home. They will prioritise the pup’s health and wellness above all else.
The Role of Nutrition and the Developing Gut During Weaning
by Retha van der Walt, Specialist Raw Nutritionist
During the first weeks of life, a puppy’s gut microbiome is undergoing rapid and highly sensitive development. Much of this early microbial community is acquired directly from the mother, through close physical contact after birth and through her milk, which provides a diverse range of beneficial bacteria that help shape immunity and digestive stability. As puppies grow from a few days old to approximately six weeks, the variety of microbial species in the gut increases significantly, with key shifts occurring as their bodies prepare for and adapt to solid food. Interrupting this process too soon, by removing the puppy before eight weeks, can destabilise microbiome development and make them more prone to digestive issues and lowered immune resilience. Nutrition during weaning also has a powerful influence: diets high in heavily processed grains or low-quality animal by-products tend to promote bacterial populations linked with inflammation and poor metabolic health. Allowing the puppy to complete weaning naturally, with appropriate, digestible, high-quality food introduced gradually, creates the foundation for a balanced gut ecosystem and healthier long-term development.

FAQ Section
Q: When should I bring my puppy home?
A: Most vets and behaviourists recommend bringing your puppy home at 8 weeks old, not before. This gives them extra time with their mother and littermates to develop bite inhibition, social skills and confidence, which supports healthier long-term behaviour.
Q: Why do puppies need to stay with their mother until 8 weeks?
A: Puppies learn essential skills from their mother and littermates during this time, including gentle play, reading canine body language and coping with frustration. Removing a puppy too early can interfere with this development and increase the risk of behavioural issues later on.
Q: What happens if a puppy is separated from its litter too early?
A: Research has linked early separation (around 4-6 weeks) with higher rates of destructiveness, excessive barking, possessiveness and fear-related behaviours such as noise sensitivity. Early removal may also affect gut health during the sensitive weaning period.
Q: Is it ever okay to remove a puppy from its litter before 8 weeks?
A: Yes, in specific situations. If a puppy is in an unsafe, unhygienic or neglectful breeding environment, early relocation may be in its best interest. However, buying from such breeders can fund poor practices, so it’s better to report concerns to the SPCA.
Q: How can I tell if a breeder is reputable?
A: A reputable breeder won’t rush you to collect your puppy before 8 weeks. Look for a clean, safe and enriched environment, a healthy mother, an active socialisation plan and a breeder who prioritises the puppy’s wellbeing over a quick sale.
