5. Flemish Giant
This bunny may tip the scales anywhere between 13 and 14 pounds. It has even been known to reach 22 pounds or more, which would probably make it a heavy weight fighter in the World Rabbit Boxing Association -- if there actually were such an association. The Flemish Giant is very laid back, more dog-like than rabbit. It comes in various colors, including black, blue, fawn, gray and white, and it is one of the oldest recognized rabbit breeds. It's like owning a humongous, long-eared piece of the past.
