Bringing home a new puppy is one of the most exciting — and overwhelming — experiences a dog owner can have. The decisions you make in the first few weeks have a profound effect on your puppy's behavior, health, and emotional wellbeing for the rest of their life. This comprehensive puppy care guide walks you through everything you need to know, from puppy-proofing your home before they arrive to starting basic training in week one.
Before Your Puppy Comes Home
Preparation makes the first days dramatically smoother. Here's what to have ready:
- Crate: Dog-sized (not too big), with a soft blanket and a worn T-shirt that smells like you.
- Food and water bowls: Stainless steel or ceramic are easiest to clean and most hygienic.
- Puppy food: Ask the breeder or rescue what the puppy has been eating and continue with that food initially to avoid digestive upset. Transition slowly if needed.
- Collar and ID tag: Even indoors, a collar with your phone number is important from day one.
- Leash and harness: For early leash introduction and outdoor potty trips.
- Safe toys: A few chew toys, a rope toy, and a soft toy. Avoid toys with parts that could be swallowed. See our Dog Toy Safety Guide.
- Enzyme cleaner: You will need this for accidents. Buy it before the puppy arrives.
- Baby gate: To limit your puppy to a manageable area of your home.
- Vet appointment: Book a first vet visit for within 48–72 hours of bringing your puppy home.
The First 3 Days: What to Expect
The "3-3-3 rule" for rescue dogs applies loosely to all puppies: Day 1–3 is shock and overwhelm, Days 4–14 is gradual settling, and months 1–3 is when your puppy truly relaxes and shows their real personality.
Day 1
Keep things calm and quiet. Limit visitors. Let your puppy explore the areas you've designated at their own pace. Introduce the crate as a fun, safe space with treats. Don't force them inside — let them choose to enter. Start the potty training schedule from hour one. See our Puppy Potty Training Guide for a full schedule.
Days 2–3
Your puppy may cry at night, refuse to eat, or sleep excessively. This is completely normal — they are processing an enormous life change. Maintain the routine calmly. Don't give in to nighttime crying by taking the puppy to your bed unless you intend to continue this long-term.
Feeding Your New Puppy
Puppies have very different nutritional needs from adult dogs. They need more calories per pound of body weight, more protein, and specific calcium-to-phosphorus ratios for healthy bone development.
🍖 Puppy Feeding Basics
- Feed a food labeled "for puppies" or "for all life stages" — never adult-only food
- Large and giant breed puppies need food specifically formulated for large breeds
- 8–12 weeks: Feed 3–4 times per day
- 12 weeks–6 months: Feed 3 times per day
- 6–12 months: Transition to 2 times per day
- Always have fresh water available (except 1–2 hrs before bedtime)
- Do not free-feed — scheduled meals make potty training much easier
See our complete Puppy Feeding Guide for portion sizes by weight and breed, or use our Puppy Food Calculator to get exact daily amounts.
Sleep and Rest Needs
New puppy owners are often surprised by how much their puppy sleeps. This is completely normal — puppies need 16–20 hours of sleep per day for healthy brain and body development.
Never wake a sleeping puppy unnecessarily. Sleep is when the brain processes new learning and when the body grows. Overtired puppies are bitey, anxious, and difficult to train.
Enforced rest periods (putting your puppy in their crate for a nap every 2 hours) are one of the best things you can do. A rested puppy is a trainable puppy. See our Puppy Sleep Calculator for daily sleep recommendations by age.
First Vet Visit Checklist
Your first vet visit should happen within 48–72 hours of bringing your puppy home. Here's what will happen:
- Physical examination: Head-to-tail health check including heart, lungs, eyes, ears, teeth, joints, and abdomen.
- Weight and growth assessment: A baseline weight that future visits will compare to.
- Vaccination schedule: Most puppies start vaccines at 6–8 weeks and need boosters every 2–4 weeks until 16 weeks. See our Puppy Vaccine Schedule Calculator.
- Deworming: Most puppies are born with intestinal parasites. Your vet will prescribe an appropriate dewormer. See our Deworming Schedule Calculator.
- Flea/tick prevention: Start prevention early, especially in spring and summer.
- Microchipping: Recommended at the first visit for permanent ID.
- Questions to ask: Spay/neuter timing, appropriate diet, dental care, next appointment.
Early Socialization (The Critical Window)
The socialization window — 3 to 14 weeks — is the most important developmental period in your puppy's life. Positive experiences during this window shape how your dog reacts to the world for life. Missing this window is one of the leading causes of fearful, reactive adult dogs.
See our dedicated Puppy Socialization Guide for a full socialization checklist and timeline.
Starting Basic Training
Begin training from day one — not week four. Puppies as young as 7–8 weeks can learn sit, watch me, and name recognition. Short 3–5 minute sessions, 3–4 times per day, are ideal. Use high-value treats and end on a success. See our Puppy Training Schedule for a full daily plan.
Puppy-Proofing Your Home
- Secure all electrical cords (puppies chew them)
- Put cleaning products and medications in locked or high cabinets
- Remove toxic plants (lilies, azaleas, sago palm, grapes, raisins)
- Block access to stairs until coordination improves (usually 12+ weeks)
- Secure trash cans with locking lids
- Use baby gates to limit free-roaming access
- Check for small objects your puppy could swallow — coins, rubber bands, hair ties
Frequently Asked Questions
Puppies can go into your private backyard immediately if it is clean and not frequented by unknown dogs. Public areas (dog parks, sidewalks, pet stores) should wait until 1–2 weeks after the final puppy vaccine (usually around 16–18 weeks). You can still socialize before then by carrying your puppy or having controlled visits with vaccinated dogs.
Place the crate next to your bed so your puppy can hear and smell you. A warm water bottle under the blanket mimics littermates. A ticking clock can replicate the mother's heartbeat. Most puppies stop crying at night within 2–5 days if you are consistent and do not reinforce the crying by taking them out of the crate (unless they genuinely need to potty).
Core vaccines for puppies include DHPP (distemper, hepatitis, parvovirus, parainfluenza) given every 3–4 weeks from 6–8 weeks until 16 weeks, then a booster at 1 year. Rabies is given at 12–16 weeks. Non-core vaccines like bordetella, leptospirosis, and Lyme may be recommended based on your lifestyle. Use our Vaccine Schedule Calculator for your specific puppy.
Your First Vet Visit
Schedule your first vet appointment within the first 48–72 hours of bringing your puppy home, even if they appear healthy. The initial exam establishes a health baseline, checks for any issues the breeder or rescue may have missed, begins the vaccine series if due, and starts the deworming protocol. Your vet will also become your most important resource for questions over the coming months — establishing this relationship early matters.
Bring any health records provided by the breeder or rescue, including previous vaccines, deworming dates, and any known health history. If you have a specific food question, bring the bag you are currently feeding. Write down your questions beforehand — first appointments move quickly and it is easy to forget things you wanted to ask.

Sleep — More Than You Expect
Puppies sleep 16–20 hours per day, and this is not optional — it is essential for healthy brain development, immune function, and growth hormone release. Trying to keep a puppy awake to maximize socialization or playtime is counterproductive: overtired puppies lose impulse control, bite harder, and have dramatically worse behavior than well-rested ones.
Enforce nap times proactively. After 1–2 hours of activity — play, training, a walk, any stimulation — put your puppy in their crate for a nap whether they seem tired or not. They will fall asleep within minutes in most cases. A puppy who has rested adequately is a focused, trainable, gentle companion. A puppy who has been awake for 4 hours is a biting, frantic, inconsolable problem.

Complete Puppy-Proofing Checklist
Before your puppy arrives, walk through your home at puppy level. Literally get on your hands and knees and look at what a puppy sees — electrical cords at nose height, interesting objects within reach, gaps behind furniture where a puppy can get stuck.
- Electrical cords: Tuck or cover all accessible cords. Cord protectors are inexpensive and prevent both injury and expensive repairs.
- Toxic plants: Sago palm, azalea, oleander, and numerous common household plants are toxic to dogs. Check the ASPCA toxic plant list and remove or relocate anything dangerous.
- Medications and supplements: Store all medications, vitamins, and supplements in closed cabinets. Many human medications are acutely toxic to dogs in small doses.
- Trash access: Use bins with secure lids or store bins in closed cabinets. Trash raiding is both a safety risk and a behavior problem.
- Small objects: Coins, batteries, children's toys, rubber bands, hair ties — all potential swallowing hazards. Clear the floor and low surfaces.
- Toilet lids: Keep closed. Small puppies can fall in and drown.
- Stairs: Use baby gates until your puppy is large enough to navigate stairs safely and has been supervised learning to use them.
- Gaps and escape routes: Check fence gaps, spaces under gates, and any openings a small puppy could squeeze through.
