I’ve just signed Izzy up so we can complete a C-Barq questionnaire for her.
I know what you are thinking: you don’t ‘see’ barks, you hear them. Well actually, C-Barq stands for ‘Canine Behavioral Assessment and Research Questionnaire’ and it’s another example of citizen – or participatory – science.
Created by Dr. James Serpell who is a behaviorist at the Center for the Interaction of Animals and Society (CIAS) in Pennsylvania, the questionnaire is designed to provide dog owners and professionals with standardized evaluations of temperament and behavior. The Center is based within the School of Veterinary Medicine at the University of Pennsylvania.

Tested extensively for reliability and validity on large samples of dogs of many breeds, the current version consists of 101 questions describing the different ways in which dogs typically respond to common events, situations, and stimuli in their environment. It should take about 15 minutes to complete (I haven’t done this yet).
Please pay attention, however, to the sign-in page where questions are asked about your dog’s breed, background, and behavior. This helps in coding the answers for analysis.
So far, over 80,000 dogs have been included in the study. Dr Serpell says, “There is no other breed or species of animal with such a wide variety of appearance and behavior.”
Between 10 percent and 15 percent of dogs can show very high levels of aggression, Serpell says, while 20 or 30 percent show no aggression.
Pit bulls and Akitas, popular breeds for fighting and guard dog duty, show serious aggression toward other dogs. But the title for most aggressive overall actually goes to tiny dachshunds, which display heightened aggression toward dogs, strangers and even their owners.
