If by "greedy" you mean he eats all his food really fast, I would say that's very normal. I've had four Bulldogs thru the years and mine have all eaten like that. They also have run over to my other dogs' bowls to gobble up their food the second they are through eating. I have never been able to stop any of my bullies from doing that, so I always feed them in a separate place from the other dogs. I'm still feeding Winnie in her crate. So, greedy is normal at my house!
