The kids are crazy about him. I can already tell he's going to be the most patient dog ever. Vivi loves to carry him around, wrap him up in blankets, and even pull his tail, though I think we've finally broken her of that habit. It was fun seeing Vivi at first be wary of him and then wholeheartedly embrace him (literally).
Sam wants to be wherever Hux is. They chase each other around the yard and play tug-of-war all day long. The other day the kids were putting Hux in a box and covering him with a blanket, then he would peek his face out from under the blanket and Sam would squeal, "Mom! Look at his little peek face!" They are both so enamored with him and it squeezes my heart every time I see them cuddling up together or see Sam laughing uncontrollable as Hux chases at his heels.
And I don't want to jinx anything, but so far he seems like a really good dog. He knows where he's supposed to go to the bathroom (outside, of course, but also in a certain corner of the yard), and what he's allowed to chew (not that he doesn't occasionally try something else, but he's pretty good about just sticking to his own chewy things), and where he's allowed to sit. He's not perfect, of course, but I've been really happy to discover that he seems to be amenable to doing things our way, he's eager to please and happy when we're happy. He's smart and loving and very gentle with kids. We've already introduced him to most of the neighborhood kids; my apologies to all those parents who are probably being begged for a puppy right this very moment.
PS When my little brother was small he had an imaginary friend named John T-Ball Huxton. That's where we came up with Hux's name:)
PPS Thanks to Olya and her camera wizardry; turns out all-black dogs are pretty tricky to photograph, and hers came out much better than mine. That's her sweet Ivy in the yellow sweater.
