Bringing Home a New Puppy: A Complete First-Week Checklist

The first week with a new puppy sets the foundation for everything that follows. It’s exciting, exhausting, and critically important. With the right preparation and mindset, you’ll give your puppy the best possible start. Here’s your complete first-week checklist.

Before They Arrive: Puppy-Proof Your Home

Get down on puppy level and look for hazards: electrical cords, toxic plants, small objects that can be swallowed, open staircases, and gaps they could squeeze through. Secure cleaning products, medications, and foods like grapes, chocolate, and onions well out of reach. Set up a designated puppy zone — a playpen or gated area — where they can be safely confined when unsupervised.

Essential Supplies to Have Ready

You’ll need a crate sized for a puppy (with room to stand and turn, but not so large they use a corner as a bathroom), food and water bowls, age-appropriate puppy food, a collar and ID tag, a 6-foot leash, puppy pads if needed, safe chew toys, and enzymatic cleaner for inevitable accidents.

Day One: Keep It Calm

Resist the urge to invite everyone over immediately. Your puppy has just experienced the most disorienting day of their short life. Let them explore their new space quietly, offer food and water, and start introducing the crate as a cozy, positive place — never as punishment. Expect some crying on the first night. It’s completely normal.

Starting Toilet Training Immediately

Take your puppy outside every 1–2 hours during the day, immediately after waking up, after eating, and after play. Use a consistent spot and a cue word. When they go outside, celebrate enthusiastically. Puppies don’t have full bladder control until around 4 months, so accidents indoors are inevitable — clean them up without scolding.

Vet Visit in the First Week

Book a vet appointment within the first week. Your vet will do a full health check, confirm or begin the vaccination schedule, check for parasites, and discuss deworming, flea prevention, and microchipping. Bring any health records from the breeder or rescue. This visit is also your chance to ask every question you have.

Beginning Socialization

The socialization window — 3 to 14 weeks — is critical. Within the limits of their vaccination status, gently expose your puppy to different people, sounds, surfaces, and experiences. Carry them to places if needed. Well-socialized puppies grow into confident, adaptable adult dogs.

When to See a Vet Immediately

Seek urgent veterinary care if your puppy isn’t eating or drinking after 24 hours, has severe or bloody diarrhea, is vomiting repeatedly, seems extremely lethargic, or has difficulty breathing. New puppies can go downhill quickly — when in doubt, call your vet.

The first week is a whirlwind, but take a breath and enjoy it. These early days, as tiring as they are, go by incredibly fast. You’re building the foundation of a relationship that will bring you joy for years to come.
