Today at work, I was talking to a lady who owned a pug and was telling her about Honey, the puggle. The similarities are amazing...but the differences are striking. Pugs have a very smashed face and Honey has more of a snout. As such, she doesn't wheeze. She is just as stubborn as a pug though, but she howls more than barks (much like Lucy which is one of many reasons why we think she was crossed with a hound dog).
All of these thoughts...gotta post some pictures!
