Takes 5 minutes to boil vegetables with meat to fool the dogs too eat them, if you a greyhound training or something with 20 plus dogs the old it's quicker excuse you'll get away with but I'd say the average lurcher man probably ain't got more than 4 runners and if it took 10 minutes plus too sort their grub you'd be dragging it out, feeding bagged raw is abit lazy + wastes money. When it's all a wet slushy mince how do you know what someone trying to earn profit off you is putting in there?
