I have an older dog that has gotton a little sloppy on the memory birds. He takes a good line about three quarters of the way and then gets a little fuzzy and est. a hunt sometimes in the area of the fall and sometimes not. I know he is capable of doing these types of marks with not much problem I think that part of the problem is he has been running a lot of setups geared towards younger dogs as I have been running a lot of younger dogs lately Is there something I can do to sharpen up his memory birds? Should I shorten them up? run as singles first ? or run the memory bird as a single first?
