Let's see... Dakota blows bubbles, with his nose, in the water bowl, but ONLY the water bowl in my bedroom. He totally ignores the other ones and their "fun value".
He thinks game boys are the root of all evil. As soon as he sees one come out, he gets a funny look on his face and backs away.
He doesn't think that anyone should be able to swim without him being right there, monitoring their every move. Certainly, diving underwater should never be allowed. He tries to stop this by jumping in the water and climbing on people's backs. (Usually pushing them underwater) When they go under, he freaks out and starts looking for them again.
When he is bored, he will gather up every tennis ball in the house and place them all in a straight line. Then he'll lay down nearby and stare at the balls, to make sure they don't move. If one of us pesky humans knocks one of the balls out of line, he grumbles, gets up and puts it right back where it was originally, and continues staring at them. (with the occasional glare at whoever moved the ball)
He is OBSESSED with this laser pointer I got for him. He will go to the spot where I keep it, and just stare at it until I get it for him or until he falls asleep. When i do shine the light on the ground, he pounces on it and when I turn it off, he shoves his nose into my lap and waits for it to turn on again.
there are many, many more weird quirks of his... And I haven't even started on Ripley's! LOL! (Will share Rip's later)
