Well Lenny, you've inspired me! (not to mention all the great advice here). I've tried a Delta trained trainer nearby and she is going to come and spend some time with our little troublemaker to see if she can 'fix' things!

Since our dog is only small we haven't really bothered beyond what we've done ourselves. I got DP to agree to it if it means we don't have to lock her away when we're worried about a situation. So fingers crossed to the both of our doggies, Lenny!
