I LOVE pugs! I have a pug named Corky and one named Butters. Do you have dogs?
I have a Jack Russell, but not a pug. They usually have distinctive and short faces which mine does not.
I like Jack Russells too! They do share a similar size. But do they shed? Being short hair, everyone thinks pugs DON'T -- but my black clothes tell a different story!
They do. Mine sheds short white hair everywhere! Mine is white bodied and I could never wear black.
