New puppy or dog: the first-week essentials guide

The first week with a new puppy is exhausting, wonderful and overwhelming in equal measure. Here is what actually matters.

What you need before they arrive

Dog crate (sized for adult, not puppy) with bedding and a cover. Food and water bowls. Puppy food (ask the breeder/shelter what they have been eating — a sudden food change adds stress). A collar with ID tag (legally required in the UK for dogs in public). A lead. The vet's number. That is the essentials list. Everything else can be bought later.

The first week

Limit visitors. Keep noise and stimulation low. The puppy is leaving everything it knows — allow it to explore the house gradually. Begin crate training from day one — short positive sessions, not hours alone. Register with a vet in the first week. Start gentle name recognition and recall training immediately. Log sessions with our free dog training log.

The thing nobody tells you

Puppies are harder than most people expect. Sleep deprivation, chewing, toilet training accidents — the first 4–8 weeks are genuinely demanding. Most 'problem dogs' are dogs whose training was delayed or inconsistent in the first year. The effort invested in months 2–6 pays back for 10–15 years.

Frequently asked questions

How long before a puppy can go outside?
1 week after the second vaccination — typically around 13–14 weeks old. Before this, carry them outside to socialise safely (they need to see the world before the critical socialisation window closes at 16 weeks). Do not put them on the ground where unknown dogs have walked.
What is the biggest new puppy mistake?
Letting them do things as a puppy that you will not want them to do as an adult. If a 30kg dog jumping up at visitors is not acceptable, do not allow a puppy to jump up at visitors.
