Dogs
Animals with hooves usually have flat wider teeth for grinding in back of the mouth and roundish front teeth for pulling. Members of the deer family have only bottom front teeth.

Cow
If by round, you mean 'not sharp' that would be most of the vegetarian animals, such as: cows, deer and koalas. They have wider flatter teeth in order to chew plants, grass, leaves and vegetation, kind of like the molars humans have in the back of the mouth.
Carnivores have canine teeth
Animals with flat and strong teeth include herbivores such as cows, horses, and elephants. These animals rely on their flat teeth to grind tough plant material for digestion. Additionally, some omnivores like humans have flat molars that help in chewing a variety of foods.
