Connor is such a GOOD boy and would never dream of mouthing off at Mama or Daddy, much less cuss. But Neo never hesitates to let either one of us go without a "dog cussin'" if he feels it necessary!:
If you get on to him real bad, he will cuss you under his breath, just like a kid would. God forbid if you REALLY give him "what for " --he will show teeth along with the bad language!
