I got Lila (chihuahua) at 6wks, then, about two and a half months later, I got Lucy (yorkie) at 16wks. I have to tell you, it is more difficult with two... But not by much! My girls got along great from the start, no fights, ever. It was more difficult walking them for awhile, because Lila thought Lucy was just along as a play buddy and wouldn't actually walk! But they got over that eventually. And going to friends houses with my pups suddenly became a much bigger deal than it had been when I just had one. But that worked itself out too. Honestly, I found that the biggest issue came from trying to deal with two separate crates! In and out of the vet or to walk or to a friends house... It was all such a hassle trying to juggle both crates at once. But my two stinkers sorta solved that one for me on their own. I caught them cuddled up together in one crate so many times that I finally just let them stay there. I haven't used a separate crate since. Luckily, both of mine are only just over 4lbs, so they are not too heavy for this to work (they actually weigh exactly the same, to the ounce, crazily enough, which I always say is further testament to the fact that they were just meant to be together... When Lucy, a stray, found me, I think she was actually looking for Lila
).
But aside from that, my experience with two has been smooth sailing! I can honestly say I wouldn't change it for the world, and, although I can't ever imagine my life without them, it would be even more difficult to imagine
their lives without
each other.
So I guess my best advice to you is the same as it would be if you had just one... Put them on a schedule and stick to it! And be patient! Trust me... It's harder to do at first... But once you get it, it'll make your life soooo much easier!
Good luck, and I can't wait to 'meet' your beautiful babies!!!
