It's possible you're thinking of:
* Polka dots: A cow with polka dots is simply a visual representation of a cow with a specific pattern. This could be used in children's books, cartoons, or even as a brand logo.
* Branding: Some cows have dots on their hides that represent branding marks. These marks are used to identify the owner or farm of the cow.
* A specific symbol: Perhaps you've seen a cow with dots in a particular context that has a unique meaning, such as a religious icon or a brand logo.
