Your New Puppy's First Year: What to Schedule and When

The first few weeks are the easy part
You just brought your puppy home. Everything is exciting. You're taking photos, buying toys, posting on Instagram. But after the novelty wears off, the real work starts: figuring out what your puppy actually needs and when.
Puppies need a surprising amount of vet visits, vaccinations, and training in their first year. Miss a vaccination window and you're starting over. Skip socialization during the critical period and you'll deal with the consequences for years.
Here's what a typical first year looks like, broken down by age.
8 to 10 weeks: the basics
This is when most puppies come home. Your first vet visit should happen within a few days of bringing them home, even if the breeder or shelter says they're up to date.
At this visit, expect:
- A full physical exam
- First round of DHPP vaccine (distemper, hepatitis, parainfluenza, parvovirus)
- Fecal test for parasites
- Discussion about flea, tick, and heartworm prevention
You'll also want to start housetraining and crate training right away. Puppies this age need to go outside every 1 to 2 hours.
12 weeks: second round of shots
Your puppy is due for their second DHPP booster. Some vets also start the Bordetella (kennel cough) vaccine at this age, especially if your puppy will be around other dogs.
This is also the tail end of the critical socialization window. Between 8 and 14 weeks, your puppy is most open to new experiences. Expose them to different people, sounds, surfaces, and environments. Once this window closes, it gets much harder.
16 weeks: the big one
Third DHPP booster plus the rabies vaccine. In most places, rabies vaccination is legally required. Your vet will give you a certificate you'll need to keep.
By now your puppy should be comfortable with:
- Being handled (ears, paws, mouth)
- Meeting new people without fear
- Basic commands like sit and come
- Walking on a leash
If they're not, it's worth investing in a puppy training class. Group classes double as socialization, so they're well worth the time.
4 to 6 months: spay/neuter and teething
Most vets recommend spaying or neutering between 4 and 6 months, though the timing depends on breed and size. Large breeds sometimes benefit from waiting longer. Talk to your vet about what makes sense for your dog.
Your puppy is also teething around this time. They'll chew on everything. Stock up on appropriate chew toys and puppy-proof anything you don't want destroyed.
Other things happening in this window:
- Permanent teeth coming in (check for retained baby teeth)
- Increased independence and boundary-testing
- Time to start more structured training
6 to 12 months: adolescence
Welcome to the teenager phase. Your puppy might "forget" commands they knew perfectly well last month. They'll test boundaries, get distracted more easily, and generally be a handful.
Stay consistent with training. This is not the time to slack off.
Health-wise, keep up with:
- Monthly heartworm prevention
- Flea and tick treatment on schedule
- Any remaining booster vaccines your vet recommends
Around 12 months (or when your vet advises), you'll switch from puppy food to adult food. Don't do this abruptly. Mix increasing amounts of adult food over about a week.
The schedule at a glance
| Age | What's due |
|---|---|
| 8-10 weeks | First vet visit, DHPP #1, parasite check |
| 12 weeks | DHPP #2, Bordetella, socialization push |
| 16 weeks | DHPP #3, rabies vaccine |
| 4-6 months | Spay/neuter discussion, teething management |
| 6 months | Heartworm test if not done earlier |
| 12 months | Switch to adult food, annual exam, booster vaccines |
How to actually keep track of all this
Trying to remember all these dates in your head is a losing battle. Between vaccine boosters, flea treatments, grooming, and training milestones, something will slip.
That's exactly why we built Pet Care Reminder. You add your puppy's breed and age, and the app suggests a care schedule. You can tweak it however you like, set reminders for each task, and mark things off as you go. If someone else in your household is helping with the puppy, they can see the same schedule and log tasks too.
It's one less thing to keep in your head during an already hectic first year.
