Puppy Development From 4 to 6 Weeks
Share
Between 4 and 6 weeks of age, puppies change from unsteady babies into active, curious little dogs. Their movement becomes more coordinated, their baby teeth continue to appear and they begin eating, drinking, playing and exploring with greater independence.
This is also an important stage for social development. Puppies learn from their mother, littermates, breeder and surroundings every day. Play becomes more purposeful, communication improves and early lessons about bite pressure, frustration and social boundaries begin.
Although development happens quickly, puppies are still immature and need plenty of sleep, gentle handling and a safe environment. Experiences should be introduced gradually, with each puppy allowed to approach and investigate at its own pace.
Puppy Development From 4 to 6 Weeks at a Glance
- Around 4 weeks - Walking becomes steadier, baby teeth are emerging, weaning begins and interest in water increases
- Around 5 weeks - Play becomes more interactive, puppies explore further and individual personalities become clearer
- Around 6 weeks - Coordination improves, puppies eat more independently and social learning becomes increasingly important
These ages are a guide rather than a strict timetable. Breed, litter size, health, nutrition and individual development can all influence when a puppy reaches a particular milestone.
Physical Development and Coordination
At 4 weeks, many puppies can walk, sit, turn and move around the whelping area, although they may still lose their balance when excited or tired. Over the following two weeks, their muscles strengthen and their movements become smoother and more controlled.
By 6 weeks, most puppies can run, pounce, climb over low objects and change direction during play. They begin using their bodies more deliberately rather than simply wobbling towards warmth, milk or their littermates.
This increased mobility means the puppy area may need to be expanded. Puppies need enough room to sleep, play, eat and move away from their bedding to toilet. The area should remain secure, with non-slip flooring that provides grip for developing legs.
Smooth, slippery surfaces can make movement harder and may contribute to legs sliding out from under a puppy. Bedding should remain dry, flat and easy to walk across rather than forming deep folds that trap small feet.

Developing Senses and Awareness
By this stage, the eyes and ears are open and puppies are actively using sight, hearing and smell to investigate their environment. Their senses are functioning, but they are still developing and should not be treated as though they have the awareness or confidence of an older puppy.
Puppies become more responsive to voices, movement and everyday household sounds. They may turn towards a noise, follow a person with their eyes or approach the edge of the puppy area when someone enters.
Normal, low-level household activity can help puppies learn that common sights and sounds are part of everyday life. Experiences should be gentle and controlled. Sudden loud noises, forced handling or overwhelming exposure can frighten a puppy rather than build confidence.
A puppy should always have somewhere quiet to rest and the freedom to move away from an experience.
Weaning and the Move Towards Solid Food
Weaning generally begins at around 3 to 4 weeks of age and continues gradually. It is not a single event or an abrupt separation from the mother.
At first, puppies may only lick a small amount of soft food before returning to nurse. As they become more capable of eating from a dish, the consistency can be gradually thickened and the number of solid meals increased.
A complete and balanced food formulated for puppy growth should form the basis of the weaning diet. Options such as Royal Canin Starter Mousse can be served alone or used as part of the transition to a suitable puppy food.
A shallow stainless steel multi-puppy feeding pan allows several puppies to eat at once. It also makes it easier for the breeder to observe whether every puppy is reaching the food. Smaller or quieter puppies may need a separate opportunity to eat if more confident littermates continually push them away.
Food should be introduced gradually to avoid unnecessary digestive upset. Sudden changes, overfeeding and leaving wet food sitting in a warm puppy area can contribute to loose stools or contamination. For a more detailed feeding transition, see our blog post - When to Start Weaning Puppies.

Learning to Drink Water
Fresh drinking water should be introduced in a shallow, stable bowl when weaning begins, usually from around 3 to 4 weeks.
Puppies often investigate water before they understand how to drink it properly. They may put their paws in the bowl, splash, lick droplets from each other or tip the dish over. This is a normal part of learning.
By 4 to 6 weeks, puppies should have regular access to clean water as they eat more solid food and become less dependent on milk. Puppies eating wet or soaked food may initially drink less because their meals already contain plenty of moisture. Learn more in Introducing Water to Puppies During Weaning.
The bowl should be easy to reach, difficult to overturn and shallow enough for the puppies’ size. Water may need to be replaced several times each day because young puppies regularly walk through it or drop food and bedding into it.

Baby Teeth and Early Chewing
Puppies are born without visible teeth. Their deciduous teeth, commonly called baby teeth or milk teeth, begin emerging at approximately 3 to 5 weeks, although the timing varies between puppies.
As more teeth appear, puppies become better able to grip and chew soft food. They also begin experimenting with their mouths during play and exploration.
Chewing does not always mean a puppy is uncomfortable. The mouth is one of the main ways a young puppy investigates texture, movement and other puppies. Bedding, toys, hands, bowls and littermates may all be mouthed.
Any toys offered at this age should be appropriately sized, durable and free from small pieces that could be pulled off and swallowed. Puppies should be supervised with new items, particularly when several littermates are sharing the same space.

Play and Social Development
At around 4 weeks, play may consist of clumsy pawing, mouthing and short wrestling sessions. By 5 to 6 weeks, puppies begin chasing, pouncing, tugging and taking turns during more organised interactions.
Play is not simply entertainment. It helps puppies practise body control, communication and social responses. During play, they learn that biting too hard may cause another puppy to squeal, stop playing or move away.
These reactions contribute to the early development of bite inhibition, which is the ability to control the pressure of the mouth. This learning continues after puppies leave the litter, but early feedback from their mother and littermates provides an important foundation.
The mother may also interrupt overly rough behaviour, move away when puppies become demanding or limit access to nursing. These responses are part of normal maternal communication and should not automatically be interpreted as rejection.
Early Socialisation Begins in the Litter
The primary socialisation period is commonly recognised as beginning at approximately 3 weeks and continuing through the early months of life. Experiences during this stage can influence how puppies respond to people, animals, handling and unfamiliar environments.
For puppies aged 4 to 6 weeks, socialisation should remain simple, positive and appropriate for their age. Suitable experiences may include:
- Gentle handling by calm adults
- Brief contact with different safe surfaces
- Normal household sounds at a comfortable volume
- Seeing people wearing different clothing
- Short individual sessions away from the litter
- Safe objects with different shapes and textures
- Positive exposure to grooming tools without forcing restraint
Socialisation is not about exposing puppies to as many things as possible in one day. Quality matters more than quantity. A useful experience allows the puppy to notice something new without becoming overwhelmed.
Watch the puppy’s response. Approaching, sniffing and relaxed exploration suggest curiosity. Freezing, hiding, repeated attempts to escape or remaining distressed indicate that the experience needs to be reduced or stopped.

Human Handling and Early Care Routines
Gentle daily handling helps puppies become familiar with normal human contact. Breeders can briefly touch the paws, ears, mouth, body and tail while keeping each session calm and positive.
This is also a useful time to introduce simple care routines, including:
- Being lifted and held securely
- Standing briefly on digital puppy scales
- Having the feet and nails examined
- Gentle brushing
- Looking inside the ears
- Wearing correctly fitted puppy identification collars
- Short periods of calm individual attention
Puppy ID collars should be checked regularly because puppies grow quickly. They must remain comfortably fitted and appropriate for the puppy’s age, size and environment.
Handling should never become a struggle. Several short, pleasant experiences are more useful than one long session that leaves the puppy tired or distressed.

Sleep and Quiet Time Remain Important
Puppies from 4 to 6 weeks may appear energetic, but they still need a great deal of sleep. Their active periods are usually short and often followed by deep rest.
A puppy that becomes increasingly rough, noisy or unable to settle may simply be overtired. Constant handling, visitors and unrestricted play can be too much, particularly for a young litter.
Provide a warm, comfortable sleeping area away from the busier feeding and toileting zones. Puppies should be able to rest without being repeatedly disturbed.
Children should always be supervised around the litter and taught to leave sleeping puppies alone.
Toilet Habits and Keeping the Puppy Area Clean
By this age, puppies can urinate and pass faeces without stimulation from their mother. Many naturally begin moving away from their sleeping area to toilet.
Breeders can support this instinct by creating separate areas for sleeping, playing, feeding and toileting. A low-edged toilet area placed away from the bedding can help puppies begin developing clean habits.
The area should be cleaned regularly, but cleanliness does not mean removing every familiar scent or keeping puppies in a sterile environment. The goal is to control urine, faeces, spoiled food and excess moisture while maintaining a safe, comfortable living space.
Wash feeding pans and water bowls after contamination and allow them to dry properly. Bedding should be changed whenever it becomes wet or dirty.

Monitoring Growth During Weaning
Puppies should continue gaining weight as they move from milk towards solid food. Because puppies within the same litter may develop at different rates, each one should be monitored individually.
Regular weighing can help identify a puppy that is falling behind before the difference becomes visually obvious. Oz Fur Kids Free Downloadable puppy weight charts and digital tray scales can be used to record progress consistently.
Weight should be considered alongside:
- Appetite
- Energy when awake
- Stool consistency
- Hydration
- Movement and coordination
- Ability to compete for food
- General body condition
A single measurement is less useful than the pattern over several days. Breed and expected adult size also influence what healthy growth looks like, so littermates should not be expected to weigh the same.
If a puppy is falling behind, How to Tell if a Puppy Is Getting Enough Milk explains the feeding, behaviour and weight changes to monitor. You can also learn more about recognising fluid loss in Signs of Dehydration in Puppies.

Developmental Differences and Warning Signs
Some variation between littermates is normal. One puppy may be more adventurous while another watches before approaching. Teeth may appear at slightly different times, and confidence with food or water can also vary.
Concerns are more significant when a puppy:
- Stops gaining weight or loses weight
- Regularly misses meals
- Remains weak or unusually quiet
- Develops persistent vomiting or diarrhoea
- Has difficulty standing or walking
- Shows a sudden change in behaviour
- Cannot compete for food or access the mother
- Appears dehydrated or unwell
If your puppy is still weak, not feeding well, or you’re unsure at any stage, it’s a good idea to check in with your veterinarian to make sure the right support is being provided.
Supporting Healthy Development From 4 to 6 Weeks
The breeder’s role during this stage is to provide good nutrition, a safe environment and opportunities for gradual learning. Puppies do not need complicated training programs or constant stimulation.
A suitable routine should include:
- Regular access to their mother
- Gradual introduction to complete puppy food
- Fresh drinking water
- Clean, non-slip living areas
- Safe opportunities to move and play
- Calm human handling
- Age-appropriate objects and surfaces
- Plenty of uninterrupted sleep
- Individual weight and health monitoring
The aim is not to make every puppy react identically. It is to give each one a secure foundation from which confidence and normal behaviour can develop.

Final Thoughts
Between 4 and 6 weeks, puppies make rapid progress in movement, feeding, communication and social behaviour. They begin eating and drinking more independently, play with greater purpose and become increasingly interested in the world outside the sleeping area.
This is a valuable time for gentle socialisation, positive handling and carefully managed exploration. Puppies still need their mother, littermates and plenty of rest, so development should be supported without rushing them into experiences they are not ready to manage.
