Is eight weeks too young to start training a puppy?

No. Eight weeks is a perfectly good age to begin gentle groundwork — name recognition, handling, toilet routine and settling into a bed or crate. Formal lead walks in public usually wait for full vaccination, but training itself can start straight away.

Should I wait until my puppy has had all their vaccinations?

For walks in public places and contact with unknown dogs, yes — follow your vet's advice on timing. For training at home, in the garden, or with dogs and people you know to be healthy, there is no need to wait.

How long should puppy training sessions be?

Keep sessions short, typically a few minutes at a time, several times a day. A young puppy's attention span is limited, and short, frequent sessions with a clear end on a success tend to work far better than one long session that ends in frustration for both of you.

What is the first thing I should teach my puppy?

Their name and a reliable recall over a short distance are usually the most useful starting points, alongside a calm routine for toileting and mealtimes. These form the foundation that later commands like sit and stay build on.

When to start training a puppy

You can start training a puppy from the day they come home, usually around eight weeks old, and there is no reason to wait for a particular age or for a full course of vaccinations to begin. What changes with age is not whether training can start, but what you train — short, gentle groundwork in the first few weeks, building up to proper obedience and lead work once your puppy is a little older and more physically capable.

Why eight weeks is not too early

The idea that puppies should not be trained until they are four or six months old is one of the more persistent myths in dog ownership, and it usually comes from confusing formal obedience classes with training itself. A puppy is learning constantly from the moment they arrive, whether or not you are deliberately teaching them anything, so the only real question is whether that learning is guided or accidental.

Early weeks are actually a strong window for the basics, because a young puppy has fewer established habits to unpick and is highly motivated by food and attention. Waiting until problems appear — jumping up, mouthing, ignoring their name — means training against a habit rather than building one from scratch, which is always the harder job.

What to work on in the first few weeks

Start with the things that make everyday life easier rather than formal commands: responding to their name, coming back to you over a short distance, sitting for their food bowl instead of scrambling for it, and getting comfortable being handled around the paws, ears and mouth. All of this can be done in five-minute bursts around the house and garden, which suits a puppy's short attention span far better than one long session.

Toilet training and settling into a crate or bed, if you are using one, are also best started immediately rather than treated as separate from 'proper' training. A consistent routine in the first fortnight — the same spot for the toilet, the same cue words, praise timed to the moment it happens — does more than any later correction.

When to add lead work and wider socialisation

Lead walking in public and structured socialisation with other dogs usually wait until your puppy has completed their vaccination course, which your vet will confirm, and that is a sensible precaution rather than a training rule. In the meantime, a lot of useful groundwork can still happen at home and in the garden: getting used to a collar or harness, walking a few steps on a loose lead indoors, and being handled calmly by different people.

Puppy classes are worth looking into once your vet has cleared your puppy for wider socialisation, because they combine training with safe, supervised contact with other dogs and people at an age when that exposure matters most.

What tends to go wrong

The most common mistake is not starting too early, it is being inconsistent — different family members using different words for the same thing, or letting a puppy get away with something one day and correcting it the next. Puppies learn from repetition and clarity, so agreeing the basic house rules before your puppy arrives saves a lot of confused, slow progress later.

The other common one is expecting too much focus for too long. A puppy's attention span at eight to twelve weeks is genuinely short, and pushing past it teaches frustration rather than the behaviour you wanted. Several short sessions a day beat one long one every time.
