It depends a lot on the dog— what I've seen with dogs is similar to what you describe with your cats. There are 4 dogs in my house, one belonging to me and three belonging to my roommate. Mine won't really overeat unless she's offered a lot of something extremely appealing (like human food). At least 2 of my roommate's dogs will eat until they make themselves sick, though. The last one, I'm not sure.
