A canine, of any sort, that has been drawn with skinny limbs and emo hair. Dog anatomy can be exaggerated to fit the maker's "style". The dog is then coloured with the brightest most irritating colours the artist can find, and covered with teen accessories to the point where looking at it makes you want to rip your eyes out and stomp on them just for registering something so hideous into your mind.
In short, an anorexic faggot dog.
Person 1: I kind of feel bad for all the sparkle dogs, just being one is asking for abuse.
Person 2: Yeah, I had one once, but I shot it, because it was just so damn ugly... I mainly did it to put the poor thing out of its misery though, ya'know?
