THE 3-3-3 RULE
Give Your Little Time to Settle, Learn & Belong
Bringing home your new little is exciting, but remember, everything they know just changed. New people, new smells, new sounds, a new routine, and no littermates beside them.
The 3-3-3 Rule is a simple way to understand the adjustment period many dogs experience during their first 3 days, 3 weeks, and 3 months in a new home. It isn’t an exact timeline or a rule every puppy will follow. Some littles settle in almost immediately, while others need more time.
Think of it as a reminder to give your puppy grace while their real personality unfolds.
Mama Tara Tip: Don’t decide who your puppy “is” based on the first few days. That quiet little angel may just be gathering information before the Boston comes fully online.
THE FIRST 3 DAYS
Decompressing
During the first few days, your little is simply trying to figure out their new world. Everything looks, smells, and sounds different.
You may notice your puppy:
Sleeping more than expected
Being extra clingy or a little unsure
Eating less than usual
Whining, especially at bedtime
Having potty accidents
Being unusually quiet or surprisingly wild
Keep their world small, calm, and predictable. Stick with the food and routine they already know, limit overwhelming introductions, and give them plenty of opportunities to rest.
Don’t expect too much too soon. Right now, your biggest job is simply helping your little understand:
“I’m safe here.”
Mama Tara Tip: Three days is not a deadline. Some littles walk in like they own the mortgage. Others need a little more time. Follow your puppy’s lead.
THE FIRST 3 WEEKS
Learning the Routine
By the first few weeks, your little is beginning to understand how life works in their new home. They’re learning your schedule, where to potty, when meals happen, where they sleep and most importantly, that you are their people.
You may notice:
More confidence and curiosity
More of their true personality coming out
Testing a few boundaries
Improvement with potty and crate routines
Becoming more comfortable being themselves
A noticeable increase in Boston shenanigans
This is a great time to keep building consistent routines and positive training. Continue working on basic manners, leash and harness skills, handling, and appropriate socialization while keeping expectations realistic for a young puppy.
And don’t be surprised if your previously perfect little angel suddenly develops some opinions. Feeling safe enough to test boundaries is part of settling in.
Mama Tara Tip: Around this point, you may start wondering what happened to that quiet little puppy you brought home. Congratulations—the Boston has officially loaded.
THE FIRST 3 MONTHS
Feeling at Home
By around three months, your little has had time to settle into the rhythm of your home. They know their people, recognize the routine, and are beginning to understand what’s expected of them.
You may notice:
A stronger bond with your family
More confidence in their surroundings
Better understanding of household routines
Continued progress with potty training and manners
Their personality coming through loud and clear
Your home officially feeling like their home too
This doesn’t mean training is finished, far from it. Your puppy is still growing, learning, and heading toward plenty of new developmental stages. Continue providing structure, positive training, socialization, and consistency as they mature.
The biggest difference? Your little is no longer trying to figure out whether they belong.
They know they do.
Mama Tara Tip: By three months, you’ll probably have trouble remembering what the house was like without them. They’ll also have trained you quite nicely by then.
A LITTLE NOTE FROM MAMA TARA
The 3-3-3 Rule isn’t about watching the calendar. It’s about remembering that adjustment takes time, and every little will move at their own pace.
Give them patience, consistency, structure, and lots of love while they figure out their new world. One day you’ll look around and realize they aren’t the “new puppy” anymore.
They’re just yours.
