I only have one dog now and have a lot of choices for my likings of breeds for later down the road, besides a Silky or another Yorkie.
I think my number two choice would be Papillon for sure. Westie's are definitely a third choice. I love any small sturdy energetic terrier, like Cairns, Border Terriers, Norwich, etc.
As for bigger-ish dogs (I will own a bigger dog
someday just not for a while until I'm in my own house), a Border Collie, Australian Shepherd or Golden Retriever. I like energetic dogs

lol. I would love a German Shepherd trained correctly (we had one growing up but never put the effort into what she was capable of) but I don't know if I have the personality for a GSD.
There's a few breeds I love but will probably never own, I don't exactly know why. I love Boston Terriers, Boxers, Rottweiler's, etc, but I probably wouldn't own them.
