As an update on Ike, I wanted to let Chris and everybody else who was concerned and helpful know that he has really "come around". I believe the construction we were undergoing (and our neighbours as well) really had him unnerved. He has been MUCH more himself lately, back to his regular sweet nature. When were were putting the second storey on our house, he wasn't allowed "up there" (too dangerous) until recently. Now that he can come upstairs while we work, insulate, drywall etc., he happily hangs out with us. Maybe it wasn't even the construction, perhaps he just missed us being downstairs with him all the time.

Oddly enough, there is one neighbourhood child whom he still barks at, and I won't let him near her off leash. It's very odd, he plays beautifully with all the other children, but this one 8 year old girl brings out the worst in him (and she's sweet, not a brat, I know she's never taunted him in any fashion, I can't figure it out).

But, he's doing beautifully. Thank you for all your advice and concern!
