Louis has this habit of hiding his treats around the house, it's not much of a big deal but one time my brother went up to him WHILE he was in the midst of "buring" a treat in the couch and he just turned into adifferent dog! he snarled and showed his teeth, and he seriously looked like a wear wolf! I was so shocked, then when he was done, he was back to happy little lou. he also has this little spot on the carpet where he's constantly scratching at (imagine like he's trying to dig a hole in the carpet) and if you go and touch the place - wear wolf! all over again! same with when he's "digging" into the blanket ...any time when he's "digging" or "burying" something ... does this happen to anyone else?
