Liz, when we adopted Snoopy, we didn't take any of the dogs with us. Knowing the other dogs temperaments works pretty well. We took Dazzi when we got Jack - if Dazzi accepted him, the others would too. Maybe we have just been lucky, but all the dogs get along well. There have been a few scuffles but it is usually over food and ends quickly with no one hurt. I just see it as the same as kids - they get into little fights too. I think if you see the new dog reacting to other dogs that it will turn out fine. As to meeting on neutral ground, it may be ideal but we haven't had too much problem when that wasn't a possibilty. (we got home with Jack about 10 or 11 at night from Kentucky - we did let each dog meet him separately though in the front yard before bringing him into the house).

Good luck, I'm sure you will find a great friend for Smokey!
