I use lots of nicknames for mine.

For Daisy, I use Doozle, mostly, but also Dizzy, Deecy, and Doodlebug. Yes, it's babytalk.

For Lily, I use Lizard, Millie, and Mary LuLu

For OJ, I use O-Jota (en Espanol), Jay, and Junebug

And for Buddy, I use Boudreaux, Budskers, and Brotha Bud

My husband says this is why our pets probably suffer from multiple personality disorder. I say it's just love talk. I call him Dinglebyrd.
