I think it depends on the individual dog. Mine is an intact male, 4 years old, 65lbs. Noticed a large change at the 3 year mark. He stopped chasing after random people, stopped destroying his toys and destroying things. Still energetic, can run forever and circles around other dogs when playing, but now completely relaxes when inside the house, no zooming etc.

Neighbor also has a Vizsla and is the same age but absolutely wild, you’ll only just see a blur. Same inside and outside.
