Where you give a back cast or send from heel, whistle stop then give cast? Then yes some, didn't know if it was too much for him.
Mowed rows in tall grass can help clearly define to the pup what you want him to do. With my first dog, I found a conservation area that had mowed rows and that helped me keep the pup running in a straight line. Also had a place where there were rows of trees planted and they was mowing between the rows of trees and kept everything around the young trees unmowed, so could push the pup out on longer blind retrieves. Also happened to find a place where I could do T's the same way. After running drills where he had a defined line to run, moved it out into a open stubble field or short field, then incorporated it into marshes, tall grass, etc.
