Temperament testing in dogs commonly includes exposure to dolls or dogs. This experiment attempted to validate the use of novel devices in testing. Three groups of dogs were recruited: dogs with known aggression toward children (CHILD-AG, n = 11) or other dogs (DOG-AG,
n = 12) and a control group (n = 11). Dogs were exposed to 4 novel stimuli: an unknown woman, a life-sized doll to mimic a child, a fake dog, and an ambiguous item (a garbage bag filled with crumpled paper and paper eyes glued to the front).

When presented with the doll, 6 CHILD-AG, 2 DOG-AG, and 1 control dog growled or snapped at the doll, although none showed sustained biting. With the ambiguous item, 4 CHILD-AG and 1 DOG-AG dog exhibited barking, the only behavior that was significantly different among groups. Fearful reactions were elicited by the ambiguous item in almost all CHILD-AG and DOG-AG dogs while only 4 control dogs showed fear. Three CHILD-AG, 2 DOG-AG, and 1 control dog showed aggressive reactions to the fake dog. The child-like doll and the fake dog elicited a range of reactions, but there was some correlation with aggressive behavior. The devices may be useful, but the authors cautioned against using only 1 test for behavior assessment.

Commentary
Temperament testing has become a common procedure performed by breeders, trainers, and shelters to help predict the emotional characteristics of a dog before adoption. Unfortunately, there is no recognized standard testing procedure. Testing gives a snapshot of behavior at a specific time, location, and situation and may not correlate with future behavior. Thus, I advise clients to watch the dog in a variety of situations. Meeting other relatives of the dog and littermates can help paint a bigger picture for the adoptive family. Regardless of how temperament testing is performed, results may vary and need to be accepted with that in mind.—Sandra Sawchuk, DVM, MS
