Are chihuahuas bigger than a snazzier?

It seems you're asking about the size of a Chihuahua compared to a "snazzier." There's no animal called a "snazzier." It's possible you're referring to a different breed, or the word is misspelled.

Could you clarify what you mean by "snazzier"?

Once I know what breed you're referring to, I can tell you if Chihuahuas are bigger or smaller.
