I have no idea what just happened, or why. My *always* sweet, gentle JoJo turned into a different, EVIL dog a little while ago.

I was trying to get him to lay down so we can go to bed, and normally he snuggles up beside me and falls asleep. Tonight however, he suddenly got a huge surge of energy right at that moment and jumped off the bed and began to chew the metal bed frame. He's never done that before.

Another thing he's never done is bark and growl at me...yet that's what he did when I said "No", and he showed his teeth! But the worst part was when I went to take a sock out of his mouth that he'd gotten out of the basket. Normally he'll try to hang on to it, eventually relinquishing the item. This time he growled at me really loud and then he bit me HARD! He even drew blood on two of my fingers! He has NEVER bitten me before and it freaked me out.

Then he ran out into the hallway and started running around the house like he was on speed...just randomly running all over like a maniac. I didn't know what to do (at this point I wished I had his crate that I'd forgotten at my dad's house, at least just to calm him down and for me to stop freaking out). I finally caught him and brought him back to bed with me and as quickly as it began, he calmed down and returned to his normal, sweet self. Literally like a switch was turned off.

As I'm typing this (laptop on my bed) he's snuggled up in my lap and has been licking me. Actually, now that I look down at him he's sound asleep.

What happened to my dog during that half hour?? He's been with me and only me for the past week, and absolutely nothing has changed with his diet, routine, etc. Again, he is 15 months old and he's NEVER EVER done this before. He is the normally sweetest dog I've ever had! Although the episode is over, I'm still very concerned and still freaking out. Can anyone please shed some light on this "temporary" crazy behavior?
