I'd say anything with noticably unnatural colors can be considered a sparkledog (including the legions of red and black wolves), but even more so with neon, scene hair, and two tons of accessories. That said, I also think not all sparkledogs are bad; I've seen some that are really pretty and/or cool. My only pet peeve is when people combine colors willy-nilly with absolutely no concept of which combinations might induce vomiting. I swear, magenta-and-chartreuse anything should be banned...
