Values are number (%) or number. Aggression was directed to children, adults, or both. “Situation does not apply” refers to situations or provocations that do not occur for the particular dog. For example, resource guarding cannot be assessed if owners have not attempted to remove food or toys. In the aggression screen, positive responses refer to growling, baring teeth, lunging, snapping, or biting a person in response to the listed stimulus. In the anxiety screen, positive responses refer to trembling, panting, pacing, vocalization, destructiveness, urination, or defecation. Anxiety screen rows may not add up to 103 because of missing values.
