There's been a trend(on deviantart) of making food dog species.I don't see anything wrong with that.However,the people who make them tend to act as if they're the only ones who could ever think of that and attack other people who make them,even people who haven't seen their food dogs before that point and wouldn't know about them.While they're not a very original concept(Food animals has been done tons of times),they're very cute.
