Toby (a lurcher) has human name Toby K. (after Toby Kieth...we rescued him as a puppy where he had been named Johny C. (after Johny Cash) we wanted to keep with the country singer idea and chose Toby)

Scout (Aussie) was named when I got him and I'd say that's not a human name.

Cinnamon (Poodle) does not have a human name (Full Name is Am. UKC CH. Precious Cinnamon V) so I guess you could say Cinnamon could be considered a middle name?? lol

Willow (Aussie) also does not have a human name.

Beau (Cockatiel) doesn't have a human name

Nor do Buddy, Boo or Ivy. (the cats)

So I guess only one of them has a human name.
