I have nothing against Vegans. Sure they're the butt of everyone's jokes, but that's not really because of their lifestyle, just their superior, holier-than-thou attitude about how everyone else in the world is evil for eating fish and chicken. If you want to be Vegan, more power to you! I'm sure you can lead a healthy lifestyle and there are plenty of people who have proven they can, due to human biology.
Dog biology, however, is very different. And it pisses me off to think that some Vegans force their lifestyle on pets who are carnivorous by nature.
Like this person who posted a sad looking picture of her dog on Tumblr, boasting about how happy they are to eat the vegan meal they prepared.
