Actually, my wife (who briefly played Jihun Sujui, as some of you who were in Ghost Festival might remember) had a lovely suggestion for an alternate miniature slaver (perhaps a variant?), the "sleeve terror."
This is a miniature slaver that is indeed bred from the runts of the litter, but not from the stupidest or the most placid. It displays all the primary characteristics of a slaver dog, including agility, aggression, and fierce loyalty, but is roughly the size of a large Chihuahua. Its leaping capability is slightly greater-than-proportional to its size; it cannot leap as high or far as a full-sized slaver, but can easily pounce straight across a mid-sized room at, not coincidentally, neck height.
These are popular as pets, and a concealed form of personal defense, among certain Amarrian nobles, especially women, who commonly carry pairs of them in their long, loose sleeves.
For those of you who have played "Dark Souls," imagine the Doom Chihuahuas from Blight Town, only with better jumping and without the fire breath. Oh, and, of course, much more cute and fuzzy.
(I love being married to this woman.)
Edit:
Oh, and they've been bred to salivate less, or only at appropriate times, so as to limit the need for extra-absorbent sleeves.
