I just got my 10 month old YLF back from 8 weeks of formal training and had a question for all of you. I did contact her trainer and am waiting for a call back. She has been great with all commands but I'm wondering how to go about her play time in the yard, etc. Should I follow all commands (fetch, heel, hold, sit, mark......) when playing with a ball, etc? Including strict e-collar correction or should some of these play times be more relaxed. Any feedback would be appreciated.
