I love it! I would like it for a girls name but it's my husband's nickname. (Don't ask me where it came from - I have no idea).
I have always loved it. Is your DH thinking of the book Good Dog Daisy? We have it, and it's really cute.

I am trying to think of what what go with it.. Claudia, Mia, Ann. Hmmm not sure about any of those. I'll keep thinking..
