Nobody tells you that the hardest part of the first three months with a puppy is not the puppy. It is figuring out, between two tired adults, who is doing what, when. This is a week-by-week playbook for couples and families who want to come out of the puppy-rearing phase with their relationship and their rug intact.

We will move through the first 90 days in five chunks. Each one has a small set of habits to build, a small set of things to track, and a small number of conversations to have with the other adults in the household. If you skim, skim the section that matches the week you are in.

Week 1: survival mode is fine

The first week with a new puppy is short on sleep and long on small accidents. Do not try to set up a spreadsheet on day one. The single most important thing you can do this week is agree, out loud, on two things: who handles the 6am potty break, and who handles the 11pm one. Everything else can wait.

What to actually track week one:

Potty timing. Not duration, not type, just times. You are looking for a pattern. Most puppies need to go out within 15 minutes of eating, drinking, waking up, or playing. Even a rough log of times reveals this within four or five days.
Meal times and amounts. Two people in the house means two chances of double-feeding. Even a sticky note on the fridge is better than nothing. Write down what you put in the bowl, initial it, done.
Anything the breeder or shelter said. Worming dates, the food brand the puppy was weaned on, microchip number, any quirks. These are easy to lose in week three, painful to recover.

Week one is not the week to invent a 14-tab tracking system. Pick one place, a shared note, a whiteboard, an app like PawLog, and put just those three things there. We will add more next week.

Weeks 2 to 3: the routine emerges

Around day 8 you start to notice a pattern. The puppy reliably needs to go out 20 minutes after breakfast. Naps cluster in the late morning. There is a 7pm zoomie session that no force on earth can prevent. This is the week to formalise the routine so you and your partner are no longer reinventing the day every morning.

The conversation to have this week, before the routine sets in by accident:

Who is responsible for which meals on which days?
Who takes the morning walk on workdays? On weekends?
What happens if both of you are out at 2pm? (Hint: not "the puppy will be fine.")
Who handles the next vet visit?

The reason to have this conversation now, in writing, is that the puppy is mostly cute right now. By week six you will be tired and one of you will say "I always do the morning walk" and the other will disagree and the puppy will be the only one having a nice time. A shared log of who actually did what short-circuits that whole conversation: you both look at the same timeline.

What we have seen work for couples

The households that have an easy time of it tend to do one of two things. Either they fully split duties by time-of-day, one person owns mornings, the other owns evenings, no negotiation, or they swap days so each person has a fully on-duty day. What does not work is "we will figure it out as we go." The ambiguity is the cost.

Weeks 4 to 6: vet visits and vaccinations

Your puppy will see the vet at least twice in this stretch, usually for the second and third sets of core vaccinations (DHPP). Three things to have ready before the appointment:

A feeding log. The vet will ask how much the puppy is eating and how often. "I think he eats three times a day" is fine. "Three meals a day at 7am / 12pm / 6pm, half a cup each, plus morning training treats" is much better.
A potty log. Number of accidents per day, whether the stool is firm. The vet uses this to flag early GI issues. If you have been tracking, this is a 20-second screenshot. If not, you are guessing.
A weight history. Most clinics weigh on every visit. Write the numbers down somewhere durable. The growth curve is the single best early indicator of whether the puppy is thriving.

It is also the right time to set up a calendar of upcoming vaccinations and boosters. The DHPP and rabies schedules are not flexible. Missing the booster window means restarting the series. A puppy tracker app worth its salt should have a vaccination tab that does this automatically. If yours does not, a recurring calendar reminder works fine.

Weeks 7 to 10: the socialization window

There is a real, time-bound period when puppies form most of their lifelong reactions to the world. Roughly week 3 to week 16, peaking in weeks 7 to 12. Dogs who do not meet a lot of new people, sounds, surfaces, and other dogs in this window tend to be more fearful as adults. This is the most important training period of your dog's life.

What to track in this stretch, beyond the basics:

Socialization variety. Aim for at least one new experience per day, a new floor type, a new sound, a person of a different age or appearance, another dog. A short note ("met toddler in park, fine") is enough to know you are covering the bases.
Training reps. If you are working on sit / down / recall / leave-it / place, logging the number of reps per session makes it obvious which commands are getting practice and which are not. Five short sessions of three reps each beats one long session of fifteen.
What scared the puppy. Vacuum cleaner? Skateboards? Men in hats? Knowing the triggers early lets you build positive exposure systematically, which is much more effective than trying to undo a fear after the fact.

If you have a partner or family member doing some of the walks, weeks 7 to 10 are when their logging pays the biggest dividend. The puppy needs to meet the world from multiple angles, not just yours. Splitting socialization across caregivers is a feature, not a compromise, as long as everyone is writing down what happened.

Weeks 11 to 13: scaling up, settling in

By the end of month three, most puppies are sleeping mostly through the night, holding their bladder for 4 to 5 hours, and developing real personality. The household routine is starting to feel less emergency-room and more "we have a dog." The temptation here is to stop tracking because the immediate pressure is off.

The thing to track in this stretch is the stuff you will want to look back on. Photos on activities are worth a lot more in six months than they feel like now. Weight checks every two weeks let you spot a growth-curve hiccup before the vet does. A weekly summary of activity and behaviour gives you a baseline for "what is normal for our dog," which is wildly useful if anything changes later.

It is also the right time to expand the household sharing. If grandma is going to watch the puppy on Tuesdays, add her now. If the kids are old enough to take a walk, give them a way to log it. The app stops being your project and starts being the family's record, which is the whole point.

The unfair advantage: a single source of truth

Most of the household tension in the first 90 days does not come from the puppy. It comes from not knowing what the other person did. "Has he eaten?" "Did you walk him at lunch?" "What time was his last potty break?" These questions, asked across a kitchen at 7pm, are the actual source of stress. The puppy is fine.

A shared log, whatever form it takes, eliminates the question. You both look at the same timeline. The double-feeding does not happen because one of you sees the other already logged breakfast. The "who is walking him tonight" debate ends because the schedule is on the same screen as the activity log. The household calms down.

The reason we built PawLog the way we did, family sharing free forever, one subscription per household, the timeline updating in real time across phones, is that this is the actual problem worth solving. Tracking the dog is easy. Tracking the dog as a family, without paying per seat or shouting across the apartment, is what makes the first 90 days survivable.

If you want to try this approach, the 90-day Plus trial lines up with the playbook above almost exactly. You get the full app for the full period covered in this guide, no card, no countdown timer. After that, the free tier keeps the essentials going.

A short checklist to take with you

Pick one place to log. Stick to it.
Agree, in writing, on who owns the morning and evening routines.
Track potty times for the first 14 days. The pattern reveals itself.
Log meals to prevent double-feeding. This is the single highest-ROI habit.
Set vaccination reminders during the first vet visit, not after the third.
Use weeks 7 to 10 to expose the puppy to as much variety as possible. Track what worked.
Add other caregivers as soon as you have a system that works.
Take photos. You will not remember this clearly in six months.

The puppy is small for a much shorter time than it feels right now. The household routines you build this quarter are the ones you will live with for years. Pick the small habits, log the small things, and the rest tends to take care of itself.
