LORELAI: If you want Jess, that’s fine – go get him, there he is. If you think that’s the great love of your life, then great . . . grab a liver treat and a squeaky toy and run to him.

She seems to suggest that Rory is acting like a “bitch in heat” over Jess, or is acting like a “dog” towards Dean.
