Agonistic pucker
A vertical retraction of the lips, with or without
baring of the front teeth.
(Fox, 1971; Goodmann et al.,
2002; Koler-Matznick et al., 2005)
This Siberian Husky mix is
exhibiting an agonistic pucker: her lips are retracted
vertically (the commissures are pushed forward) and the
canines and incisors are visible.
The Airedale puppy is
walking in front of the female German Shepherd cross;
the adult female reacts by staring and exhibiting an
agonistic pucker. The puppy averts her gaze, turning her
head.

The mixed breed female trots toward the male Golden
Retriever (who is sitting) and stretches her muzzle
forward for olfactory exploration at a distance, then
stiffens, moves away and closes her eyes. The Golden
Retriever leaps forward with paws wide open; the female
swerves to the side, then re-orients in a frontal stance
with a back-off posture, exhibiting an agonistic
pucker. When the male exhibits a rear approach,
the female lowers her tail, then moves away. When the
male follows her, she stops, glances at him and flicks
her tongue; the male licks his nose and orients toward
her head, maintaining a lateral stance. The female
reacts with an offensive facial display and an agonistic
pucker, and the male averts his gaze.

The male Border Collie lies down following a cue from
his owner. Several Pyrenees Mountain Dog puppies
approach. The Border Collie reacts by exhibiting an agonistic
pucker and offensive facial display. One of the
puppies reacts by lying down and avoiding eye contact,
wagging his tail and then moving away. Another puppy
moves away, while the last puppy avoids eye contact,
circles around the Border Collie and then approaches
him. The Border Collie responds with an intense agonistic
pucker and flicks his tongue.
