You can easily tell the difference in appearance between a Boston terrier and a pug. For example, Boston terriers have ears that point upwards, while pugs have floppy and long ears that hang near their eyes. Boston terriers also have distinct stripes or markings on their faces, in between their eyes, while pugs do not have the same markings. https://opensea.io/assets/matic/0x2953399124f0cbb46d2cbacd8a89cf0599974963/96203920715680885258366468665050395044696175479545047973777732752737793212428/
