Rocky had us thinking this for a little while. Our main concern is his antler. He has this deer antler (naturally shed, they sell them at pet stores) that he chews on. It seems a bit like he's sharpening it (in the way an inmate might sharpen one end of a toothbrush to turn it into a weapon). He frequently does this, and leaves it standing on end (sharp end pointed up). I didn't even think a dog could position a chew toy the way he does.
Now, Ruby has shown little twinges of evil behaviour, the creepiest was when she grabbed Nick by the neck, dug in her little nails and then just smiled at him. A loving smile, or a death threat? We can't be sure.

These two blonde haired children are out to get us. Just putting it out there, if something bad happens, we were on to them.
