Our 10 month old daschund (which we had potty trained and was doing very well) has started peeing inside again, as well as ripping up the puppy pads we are trying to put down now. She is also digging in the backyard and we can't seem to get her to stop. Any ideas on what we should be doing?

How often do you excersise her? There are so many things like this that can be solved with a good workout for your dog. It sounds like your dog may be bored, and is starting to rebel.
