Pard

    When I was small, neighbors up the street had a dog named Pard. He was black and white and tiny. I think I was told back then that he was a bulldog, but Internet image searches indicate that he was more likely a Boston terrier. I was terrified of all dogs back then, but Pard was so small that he was not very threatening. He would growl at you, but even that was more endearing than scary.
    I mention him mainly because Amelia the cat has assorted growls and harrumphs that remind me of Pard's. Of course, she is also black and white and tiny. Perhaps she's part Boston terrier.
