[Trouble1]

Thanks alot for the feedback, as I mentioned we have been going to this class for 7 weeks now, this was the first "grumbling" or incident with my dog of any kind. Her comportment and behaviour have been nothing but perfect until this point. At the time, my dog was clearly not being aggressive, she had rolled onto her back (her favorite playing position) during her down and was told by me to return to her side and although she immediately complied, she complained about it by grumbling. She wasn't the least bit interested in the dogs next to her nor were any of the other handlers upset. It was only the instructor that went over the top.

After reading your replies, I starting thinking about the fact that the instructor made us go directly from the long sit stay to the long down stay with the dog remaining in the same place. It was like that may have been a trigger for the grumbling/complaining. I am thinking that I should practice the exact same thing at home until I can do this with her being reliably and consistently quiet.

My dog responds reliably to the "quiet" command which stops her when she barks and it works for barking but she doesn't respond to it as well when she grumbles.

As for finding another competitive obedience club, unfortunately, this club is the only competitive obedience club in the area. The rest are clubs that train family type dogs so my options are limited.
