I think there should be more options for canine ears maybe. I mean, I know there are several, but for dog rps there are surpsingly few choices. For instance, the "floppy ears" look more like...well, like floppy bunny ears instead of dog ears. Maybe there should be options like "Triandular Ears" (as in Dalmations, Dachsunds, and most "floppy ears" dogs), Fluffy Ears (as in Cocker Spaniels) and "Mutt Ears" (You know, the one up, one down routine).
And maybe also a "Bob Tail"option for canines, similar to the "Lynx Tail" option for felines.
