10-Week-Old Puppy: Development, Behavior and Care

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

By ten weeks, your puppy has probably settled in, learned its name and begun to show its personality. It is a time of growing curiosity, bigger play and, for some puppies, sudden surprise at the world. Knowing what is typical helps you support your puppy.

Physical development

A ten-week-old puppy has better coordination, can run and play more energetically and is growing quickly. Baby teeth are all in, and adult teeth will start to push through in a couple of months. Puppies may have growth spurts, with big appetites followed by quieter days. Keep an eye on weight with your vet. See our puppy growth and weight chart by size.

Mental development

Ten-week-old puppies learn quickly, but their attention spans are short. They respond well to rewards and gentle guidance, and can begin to understand simple cues. They are also forming strong habits, good and bad.

Fear periods

Many puppies have a fear period at about eight to ten weeks, when something that previously seemed fine suddenly becomes frightening. If your puppy startles, hides or barks at a new thing:

• Stay calm and cheerful.
• Do not force your puppy to face the fear.
• Create distance and offer treats while it watches from a comfortable range.
• Avoid risky experiences until the phase passes, usually a few days to weeks.

See our guide to puppy fear periods.

Feeding

Continue three to four meals a day, adjusting portions as your puppy grows according to your vet's advice. Keep to the same food unless you plan a gradual change. Our guide to puppy feeding schedules explains how.

Toilet training

Your puppy may be starting to give signals, such as sniffing, circling or heading to the door. Keep the frequent schedule, and reward successes. Accidents will still happen. See our potty training schedule by age.

Training

Short sessions of two to five minutes work best.

• Sit and down: Reward and repeat.
• Come: Play recall games indoors.
• Name recognition: Keep rewarding.
• Crate and alone time: Build slowly.
• Handling: Continue gentle touching of paws, ears and mouth.
• Leash: Practice short, positive walks around the house or yard.

See our guide to first commands.

Socialization

Continue exposing your puppy to new experiences in a safe, controlled way. Introduce calm, friendly people and dogs that are healthy and vaccinated. Keep sessions short. Puppy classes can be valuable. Our socialization checklist offers ideas.

Health

Your vet will plan the next round of vaccinations, typically around this age, and continue worming. Keep vaccinations on time, since they protect your puppy from serious diseases. See our puppy vaccination schedule.

Biting and chewing

Mouthing and chewing continue. Provide toys, redirect gently and keep the environment proofed. Our guide to why puppies bite so much explains the causes.

Play and exercise

Short bursts of play and gentle walks are enough. Avoid forced exercise, such as long runs or jumping from heights, which can harm growing joints.

A typical ten-week-old day, and what to watch

Most ten-week-olds can manage a little more structure than at eight weeks. A realistic day includes four to five toilet-and-play cycles, each followed by a nap of one to two hours. Between naps, aim for a mix of a short training game, free play with safe toys and a calm chew. Watch for the classic overtired signs: frantic biting, zoomies that feel frantic rather than joyful, and sudden collapse into sleep. When you see them, put your puppy to bed rather than adding more stimulation.

Also pay attention to appetite and stools. A healthy puppy usually eats eagerly and produces firm, formed stools. Soft stools after a diet change or stressful event are common, but diarrhea that lasts more than a day, blood in the stool or a puppy that stops eating deserves a call to your vet, because young puppies dehydrate quickly.

The takeaway

Ten weeks is a stage of growth, learning and occasional uncertainty. Be patient, keep the routine steady and make every experience positive. Next, see our guide to 12-week-old puppies.
