We have Bruce (Maremma sheepdog), Jimmy (cocker spaniel, found as a stray in Jamestown, NY) and Charlie (cavalier king charles spaniel). For cats: Henry and Diana (brother and sister) and Winnie (was supposed to be a girl but isn't - so now it's short for Winston).
We also have sheep and goats with lots of other names (Elizabeth, Margaret, Little Leah, Dot, Ethel, Teddy, Dora, The Cow - which is a sheep).
