- "...My collar? I can’t take it off. I won’t. I’ll do anything else you ask me, but please don’t ask me that. It shows I’m bound to a longpaw, that I’m owned and loved and that I have a longpaw to look after. It’s so important. To all of us"

Daisy is a young, excitable westie/jack russell terrier. 
Excitable, loving and trusting. Daisy has a strong bond with Lucky. She is also eager to please, because in The Empty City a chapter begins with Daisy showing off to Lucky what she had caught, which turns out to be a vole.
Daisy is very good at hunting. She is also very good at pleasing people.
