No, It would be "The dog has eaten," or "The dog ate."Eat is the present tense. You want to match the tenses. If the dog is presently eating, you could say, "The dog eats." But if you are referring to the past eating behavior of the dog, it is as above, the dog has eaten, or the dog ate. I eat, you eat, they eat, is all present tense. Ate and eaten are both past tense, I have eaten, or I ate, etc.
