UGH I just posted a lengthy reply and of course hit the wrong button and deleted it.
WOW what a rare find for a rescue pup! Maybe he was from a litter of show dogs?
We left Rue out of her cage while we went to the store yesterday (only 40 minutes) and video taped her to see what she would do since she is so well behaved when we are home. Well I am disappointed (though not surprised) to say that she spent the whole time howling and shredding the contents of our garbage (we don't have a pantry so it's covered, but out in the open). We told her "bad dog" and put her in her cage, but she was totally oblivious that she had done anything wrong! She was just jumping up, smiling in our faces and hitting us with her ever-wagging tail– the usual. I don't know if she has ever been a family dog before, (it seems as though she has pretty good house manners apart from this) but she acts like she has never been scolded before. Or maybe its just that infamous, manipulative basenji charm. Hah!
Anyway, I think that we are going to do the DNA test, although now, every time I look at her I think that she has got to be mixed with a boxer. We will get one soon and post the results!
