Last week we spent a few days teaching Thief right "over" and left "back". Once he was proficient with that we taught left "over" and right "back".
This is his second session putting all of them together.
Please note that we are using attrition at this point for any mistakes on casting, no collar pressure. If he makes a mistake we are recalling and recasting. After a few days when we're sure he knows the casts we will start to use the ecollar.
After a week or so I will start to send him from my side instead of walking him to the pitchers mound.
