Pshaw! Obviously it's not a Rockwilder or Rottweiler. It isn't anywhere near 280 lbs! My uncle's imported German Rockwilder was so big his head hit the ceiling fan and he ate whole goats for breakfast. Without chewing.
ETA: Here's a pic of him.

I was at the dog park a few years ago and some guy was bragging up his huge "rottweiler" who was too massive to "fit" in the car. He was more than 200lbs of solid muscle.
It's amusing how people talk about how beefed up and massive their dogs are. It's a whole different end of the spectrum from what I deal with when it comes to small breeds (oh- your chihuahua weighs 3lbs? Well my cousin's weighs 1.5lbs!).
