I'm so glad you got to go see Kricket and that he is still available!
I agree that DH's feelings will probably change. At least he said you could get him.
Mine did NOT want a dog. It took quite a bit of asking on my part, and he finally agreed, but he agreement was more like, "Get it if you want." He seemed angry and annoyed at first. Any little problem was cause for huffing and puffing and a complaint.
Little by little, though, he has been changing. I could hear him downstairs sometimes, after she learned a new trick, he'd be trying it with her. Once he was playing fetch with her. I said, "You can't tell me she's not cute." His response, "I didn't want a dog." This was repeated over and over, until he finally admitted that she was cute. Not too long ago, he went to take a "catnap" on the couch, and brought her up to lie with him. He's been doing that more often.
He keeps asking me, "What kind of dog is she again?" So I know he's talking about her away from home.
And the biggie - yesterday when he got home from work and I told him she had chewed up the figure from his Polar Express train set (but that I was ordering him a new set of figures), he just said, "Lexi, you've gotta stop chewing things."
As far as names, I think letting DH name the dog is a great idea. I call Lexi so many things, that I don't think Kricket would have a hard time at all. In fact, you could still call him Kricket at times, as one of his many names. My son thinks it's funny to call Lexi "Gertrude". "Come here, Gertrude!" Because it is so much the tone of voice, that she will come to him - if she feels like it!
Good luck, and keep us posted!
