How would you let they dog know you appreciate the work they are doing?
Were you right? Push play to find out
This is to reward the dog for work well done. Use a low voice that sounds happy and appreciative
If you are on the move then use only the verbal reward. If you have stopped, perhaps at a curb, then add a manual caress too.
Why attagirl and not attaboy? When this language was developed the majority of guide dog trainers were male and the majority of guide dogs were female. This has now changed and there is more of a mix in both dogs and those that train them.
