Thanks so much for the advice you guys! We were really hoping that it was teething and not a sign of permanent bad behavior. When we had her fixed my vet pulled out the last of her baby teeth, so I figured she was done teething - I know this makes absolutely no sense as her adult teeth would still be coming in - She is my first dog ever so I'm still very much learning my way.

We've tried OUCH and it just seems to excite her more, so we stopped using it. I always feel very guilty putting her in her crate for time-outs, so we try to use that punishment only as the very last resort when she seems to be overstimulated or over excited.

I have to say though, she is only chewing us and her 30 or so doggie toys so we are probably extremely lucky! I've been reading some posts where dogs have eaten/chewed all manner of things. My goodness, they are very creative critters!
