Your puppy will not develop in a straight line.
There will be calm weeks. Then chaos. Then progress. Then regression.
This isn’t failure — it’s development.
Most “bad behavior” in the first year is developmental — not defiance.
The first year is a series of neurological upgrades happening in real time. When you understand what stage you’re in, behavior feels predictable instead of personal.

Slow down.
Build confidence gradually.

Spoiler: surgery doesn’t replace training.
Some dogs begin settling.

Return to basics.
Increase supervision.
Stay calm.
This is one of the most searched questions in dog ownership.
Puppies don’t “calm down” all at once. They mature in layers — physically first, emotionally later.
General timeline:
Energy decreases gradually.
It does not switch off overnight.
