Describe the setting
Note the place, time, nearby sounds and distance from people. A familiar skill can need an easier starting point when the environment changes.
Write what you observed
“Moved to the mat on two of three cues” is more useful than “was stubborn”. Include the cue, reward and breaks so another session can be compared fairly.
Choose one next step
Change just one part of the next practice. A training record describes learning; it does not replace a government assistance-dog identification mark or establish public-access eligibility.
