How Old Should a Puppy Be Before Going Home?

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

A puppy's first weeks are a period of rapid learning, and much of that education happens with its mother and littermates. Taking a puppy home too early can undo that foundation, while leaving it too long without new experiences can also cause problems. Understanding the timing helps you make the best choice for your puppy.

The usual minimum: eight weeks

Most veterinary and welfare organizations recommend that puppies stay with their mother and littermates until at least eight weeks old, and many countries have laws setting this as the minimum age for sale. Some breeders prefer to keep puppies until ten or even twelve weeks, especially for toy breeds, as long as the puppies receive continued care and socialization.

What puppies learn from their mother and littermates

Bite inhibition

When puppies play, they bite each other. A yelp from a littermate teaches them to moderate the force. Puppies removed too early may miss this lesson and bite harder later.

Social skills

Littermates teach each other how to read body language, take turns and recover from conflict. The mother also teaches manners, including when to back off.

Confidence

Puppies that stay in a secure environment until they are ready tend to be more confident with new experiences.

Physical health

Puppies receive antibodies from their mother's milk, and weaning happens gradually. Puppies need to be fully eating solid food and have received their first vaccinations and worming treatments before leaving. Our guide to weaning puppies onto solid food explains how that process works.

Risks of going home too early

• Behavior problems, including fear, anxiety, excessive biting and difficulty with other dogs
• Health problems, such as digestive upsets, poor immunity and slow growth
• Difficulty with toilet training and routines, because the puppy has not had time to learn from its mother
• Separation distress, if the puppy has not had time to develop independence

Taking a puppy at six or seven weeks, even if the breeder says it is fine, is not in the puppy's interest. Be wary of sellers who rush you or offer discounts for early collection, which can be a sign of a mill or scam.

Risks of waiting too long

Puppies do best when they get experience of the wider world during the socialization window, which starts at around three weeks and runs through roughly fourteen weeks. A puppy that remains in a kennel with no exposure to household noises, new people and surfaces may become fearful. If a breeder keeps puppies longer, they should continue to expose them to everyday life. Our guide to the puppy socialization window explains why this matters.

Breed and size matter

• Toy and very small breeds may stay with the breeder longer, since they can be slower to develop and more prone to low blood sugar.
• Large and giant breeds are usually ready at eight to ten weeks, as long as they are socialized.
• Individual puppies vary, and a breeder should be willing to keep a puppy longer if it needs more time.

What a puppy should have before it leaves

• Be fully weaned and eating solid food
• Have had at least its first vaccination, as advised by the vet
• Have been dewormed
• Be microchipped, if required by law
• Have had gentle handling, exposure to household sounds and meeting new people
• Come with paperwork, including health records and a contract

Our guide to puppy contracts and health guarantees describes what to expect.

Rescue puppies

Orphaned or abandoned puppies are a different case, and rescues work with vets to provide the care and socialization that they need. Fosterers may use puppy-raising techniques that mimic what a mother would do. If you are adopting, ask about the puppy's age, health and background. See caring for orphan puppies.

Preparing for homecoming

Plan your puppy's arrival for a time when you can be home for at least a few days, ideally a week. Prepare your home with our puppy-proofing guide and have supplies ready from our puppy shopping list. The first night is often the hardest, so read our guide to the first night at home.

The takeaway

Give your puppy the time it needs with its mother and littermates, usually at least eight weeks, and make sure it has the health and social foundation to thrive. A little patience now pays off for years.
