Honestly, I don't think you can go wrong here either way. I think dogs do like having another dog around, for the most part. I didn't find a huge difference in having 1 vs 2 - sure it adds costs, care etc - but not much more than that. You can still travel well/easily with 2. I found that at 3 and now, 4, it's much much harder -- you can't easily travel w/ 4 at all.
When we first got Marcel, our Wylie was about 1.5 years old, so had us to himself all that time. So Wylie did become more needy, insecure, confused at first when we got Marcel - so we just gave Wylie whatever he needed from us during that time of transition...and all was well!
