16–20 weeks · Puppy development

Your 4-month-old Rottweiler just discovered selective hearing.

They’re bigger, stronger and much more interested in the world. This month is about keeping training fun while turning puppy manners into habits that still work when your Rottie becomes a serious-sized dog.

At a glance

What changes at 4 months?

Your puppy may suddenly look much more grown-up, but mentally they are still very young. Expect progress and boundary testing to happen at the same time.

Body
More muscle

Height and strength can increase surprisingly quickly.

Teeth
Adult teeth

Teething is becoming a serious hobby.

Behavior
More independent

The world is becoming more interesting than your living room.

Training
Better focus

But also more testing of rules and boundaries.

Energy
Increasing

Use training, sniffing and play to channel it.

Confidence
Growing fast

Keep socialization calm and positive.

Selective hearing

“Come!” … “Sorry, I’m busy smelling this leaf.”

Your puppy hasn’t forgotten everything. They are simply learning that the outside world contains dogs, smells, leaves, people and approximately 14,000 things more exciting than your voice.

Fix: lower the difficulty. Practice known cues in slightly more distracting places instead of jumping straight from the kitchen to the busiest park.
Progression

Make distractions part of the lesson.

1. Quiet room2. Garden3. Quiet street4. Mild distractions5. New location6. Bigger distractions

Only increase difficulty when your puppy can still succeed. A long line is extremely useful for recall practice during this stage.

Training priorities

Train the dog you’re going to have — not just the puppy you have today.

A cute 16-week-old puppy pulling toward visitors is manageable. A powerful adult Rottweiler doing the same thing is a completely different experience.

Calm greetings

Place training

Teach your puppy that doing absolutely nothing can also earn rewards.

Socialization

Neutral is a superpower.

Your Rottweiler does not need to greet every person or dog. A valuable adult skill is being able to notice something unfamiliar and calmly move on.

Equipment check

Your puppy may have outgrown more than you think.

Rottweilers grow incredibly quickly. Check fit weekly rather than waiting until something looks obviously too small.

RottieBuddy tip

Adjustable beats expensive.

Your four-month-old puppy may outgrow equipment very quickly. Prioritize correct fit, security and durability over buying premium gear that may only fit for a few weeks.

Weekly habit: slide two fingers under the collar and inspect straps, buckles and crate clearance.
Skill check

What should a 4-month-old Rottweiler know?

Not perfectly. Not everywhere. The goal is that your puppy is beginning to understand these skills and can practice them with increasing consistency.

Don’t confuse adolescence with disobedience yet

Your puppy is becoming more independent, but the bigger adolescent phase is still ahead. Consistency now gives you a much better foundation when hormones, confidence and strength increase further.

Common questions

4-month-old Rottweiler FAQ

Why has my 4-month-old Rottweiler stopped listening?

Usually they have not forgotten the cue. The environment has become more rewarding and distracting. Lower the difficulty and rebuild reliability gradually.

How much training should a 4-month-old puppy do?

Use several short sessions throughout the day. Everyday moments such as doors, meals, walks and greetings are also valuable training opportunities.

Should my puppy greet every dog for socialization?

No. Calmly observing other dogs without interacting is extremely useful. Socialization should build confidence and neutrality, not an expectation that every dog is a playmate.

Is four months too early for leash training?

No. This is a useful stage for building loose-leash habits while your puppy is still relatively manageable in size.
