Hmm, it sounds like Separation Anxiety. Have you read up on this subject? If not, read read read!

For a brief summary, SA stems from dog's abnormal attachment to its family. Many puppy mill dogs develop SA in a normal household enviornment because they were separated from the litter prematurely and had not yet developed the proper social skills. Due to their rocky beginnings, the dogs often display symptoms of SA (destroying household items and furniture and urinating/defecating in areas where they normally do not).

It'd be wise to nip this behavior in the bud by making planned departures. Here's what you should do:
1) Provide your dog with a stuffed, frozen Kong, plentiful plush and puzzle toys, and a comfy dog bed.
2) Turn on the radio or TV to block outside noises. I personally close the blinds and shades on my windows since I find that helps control Giselle's SA.
3) If you want to use Rescue Remedy (www.bachflower.com/rescue_remedy.htm), this would be the perfect time to feed your dog a few droplets.
4) If you want to crate your dog, this would be a greyt time. I, on the other hand, like to close off my dogs to the living room and porch only.
5) Quietly, yet discreetly, leave the room and exit the house. Don't make a huge fuss. Just leave non-chalantly.

At first, you want to leave for just 10 minutes. Gradually, you can increase the inervals to 20 minutes, then 30 minutes, then 40. Soon, you'll be able to leave the house for hours at a time and not worry about the shape of the house. Good Luck!
