New Puppy Checklist for Pet Parents Who Want to Do Everything Right

Bringing home a new puppy is pure joy, but it also comes with serious health responsibilities. This guide walks you through vaccines, parasite prevention, microchipping, and more so you can protect your puppy with confidence from day one.

Welcoming a puppy into your home is one of the most heartwarming moments a pet guardian can experience. From the very first day, though, your role is not just to love and play with them, but also to put a solid health plan in place so they can grow into a strong, happy adult dog.

This guide breaks down what to do, when to do it, and why it matters, so you can stay organized and avoid feeling overwhelmed.

Essential Health Care Timeline For Your Puppy

Below is a general overview of the key health milestones many veterinarians in Japan recommend for puppies. Always confirm the exact schedule with your own veterinarian, as timing can vary based on your puppy’s health, breed, and local regulations.

Age / Timing	What To Do	Why It Matters
Birth to 2 months	Initial health check	Screens for congenital issues and parasites. Visit a vet as soon as your pup settles in.
6–8 weeks	First core combination vaccine	Starts protection as maternal antibodies decline and helps prevent serious infections.
9–11 weeks	Second vaccine	Acts as a booster to strengthen and stabilize immunity.
12–14 weeks	Third vaccine	Completes the puppy series; yearly boosters help maintain protection.
From 6 weeks	Flea, tick, and deworming care	Prevents and treats internal and external parasites; monthly preventives are standard.
Around 6 months	Spay or neuter surgery	Helps prevent unwanted litters, reduces certain behaviors, and lowers disease risk.
From 2 months	Microchip implantation	Required for dogs sold by breeders or pet shops in Japan; registration is also mandatory.
By 91 days of age	Rabies vaccination	The only legally mandated vaccine in Japan; must be reported to local authorities.
Once a year (adult)	Routine health check	Supports early detection of disease; twice yearly is ideal for senior dogs.

What Is Legally Required In Japan

In Japan, not every aspect of puppy health care is mandated by law. However, two elements are strictly required and should be treated as non‑negotiable by every pet parent.

Microchipping And Registration For Sold Dogs

Since June 2022, dogs sold by breeders and pet shops in Japan must be implanted with a microchip and registered in the national database. This tiny device, placed under the skin, permanently links your puppy to your contact information and greatly improves the chances of reunion if they are ever lost.

For dogs adopted from shelters, rescues, or private transfers, microchipping itself is not legally required. However, if a microchip is implanted, registration of that chip is mandatory, and experts strongly recommend microchipping all dogs as a basic safety measure.

Rabies Vaccination For All Dogs Over 91 Days

Japanese law requires every dog over 91 days of age to receive a rabies vaccination once a year. After your puppy receives the shot, you must report it to your local city, ward, or town office.

You will then receive a license tag and a vaccination certificate tag, which should be kept safely and, in many areas, attached to your dog’s collar or harness. This system helps protect public health and ensures that dogs can be quickly identified.

What Puppy Vaccines Can Help Prevent

Beyond rabies, puppies typically receive a combination (multivalent) vaccine. This is considered an essential part of preventive care, even though it is not legally mandated in Japan.

A common five‑way combination vaccine usually protects against:

Canine distemper virus
Canine parvovirus infection
Canine adenovirus type 1 and type 2
Canine parainfluenza virus

These diseases can cause severe illness, long‑term complications, or even be life‑threatening, especially in young puppies. Staying on schedule with the full puppy series is one of the most effective ways to protect your dog’s health.

Depending on your puppy’s lifestyle and environment, your veterinarian may recommend six‑, eight‑, or ten‑way vaccines that cover additional diseases. For example, puppies who often visit rivers, lakes, or rural areas may benefit from vaccines that include leptospirosis, a bacterial disease that can be transmitted through contaminated water.

How Often Should Your Puppy Have A Health Check

During puppyhood, vet visits are often tied to vaccinations and deworming. These appointments are also an opportunity to monitor growth, check for congenital issues, and discuss behavior and nutrition.

Once your dog reaches adulthood, most veterinarians recommend a comprehensive health check at least once a year. This may include a physical exam, blood tests, fecal tests, and other screenings based on age and breed.

As your dog enters their senior years—often around 7 years of age, depending on breed—twice‑yearly checkups are ideal. More frequent monitoring helps catch conditions such as kidney disease, heart problems, and tumors at an earlier, more treatable stage.

Dogs are experts at hiding discomfort, and they may appear “normal” even when something is wrong. Regular professional exams provide a safety net that observation at home alone cannot replace.

Spay And Neuter Surgery Benefits

Spaying or neutering is about more than preventing unplanned litters. Research and clinical experience suggest significant health and behavioral benefits when the timing is appropriate for the individual dog.

For male dogs, neutering can help:

Reduce the risk of benign prostatic enlargement
Lower the risk of certain testicular tumors
Decrease the likelihood of perineal hernias

For female dogs, spaying can:

Greatly reduce the risk of pyometra, a life‑threatening uterine infection
Lower the risk of mammary (breast) tumors, especially when performed before the first heat cycle

That said, the ideal age and approach to spay or neuter can vary by breed, size, and individual health status. Large and giant breeds, in particular, may benefit from a more tailored timeline. Discuss the pros, cons, and optimal timing with your veterinarian so you can make an informed decision for your puppy.

Do Not Overlook Parasite And Heartworm Prevention

Parasite control is a cornerstone of preventive care and directly affects both your puppy’s comfort and long‑term health.

One of the most serious parasitic diseases in dogs is heartworm disease (canine dirofilariasis). It is transmitted by mosquitoes, and if left untreated, worms can grow and live in the heart and lungs, leading to life‑threatening damage.

Veterinarians typically recommend starting heartworm prevention around 2 months of age, depending on the product and local risk. Preventives are usually given once a month and come in various forms, including oral medications, topical treatments, and long‑acting injections.

At the same time, year‑round flea and tick prevention is strongly advised in many regions. These parasites can cause skin irritation, allergies, anemia, and transmit serious diseases to both dogs and humans.

Modern products often combine protection against multiple parasites in a single dose. Ask your veterinarian about all‑in‑one preventives that may cover heartworm, intestinal worms, fleas, and ticks, making your monthly routine simpler and more consistent.

Caring For A Life, Not Just Meeting Legal Requirements

In Japan, rabies vaccination and microchip registration (for sold dogs) are backed by law, but responsible puppy care goes far beyond the minimum legal standard. Vaccines, parasite control, regular checkups, and thoughtful decisions about surgery all work together to protect a vulnerable young life.

Puppies are small, and even a mild illness can escalate quickly. That is why preventive medicine and routine monitoring are among the most powerful expressions of love a pet parent can offer.

Choosing to share your life with a dog means accepting a long‑term responsibility. When you turn health care into a consistent habit—appointments scheduled, preventives given on time, questions asked early—you are actively honoring that responsibility.

Your Journey Toward A Healthy, Happy Life Together

Every vaccine visit, every parasite dose, and every routine exam is a step toward a safer, more comfortable life for your puppy. By planning ahead and partnering closely with your veterinarian, you give your dog the best chance at a long, healthy, and joyful life by your side.

Start building those habits now, while your puppy is still small and adaptable. The routines you establish today will support your dog through every stage of life—and deepen the trust and bond you share for years to come.
