When your female dog will jump up in bed or on the couch with you, but will only snuggle if you pet her constantly. Otherwise, she'll jump down and go lie by herself.
"Awwwww...heyyyy Star (my dog), how's my schnuggiepoo? I gotta sleep for a little longer, so I can't pet you all day long" (puts arm around Star to snuggle and enjoy bonding). Star, not getting any petting, immediately jumps out of the bed and goes into the other room. Star is a pettinslut.
