Hi again,
Cherie's method of distraction would work with some dogs (and I'm thrilled that you managed the behavior this way before it got out of hand). The reason I didn't suggest this method for your bitch, jhack, is that she is already switched on to the chew, reward, chew, reward cycle. If you try the distraction method at this stage your bitch is going to see the distraction as a reward.
As in,"I used to chew and get petted, now I chew and get a toy!"
Don't get me wrong, if you stop this behaviour before it is established all the better but in this case it is well and truly ingrained.
As soon as you get to a minute without chewing let me know as there are some extras you can throw in at this time to help. What does your family think of my suggestions?
