Behavioural testing for aggression in the domestic dog.
Applied Animal Behaviour Science 52:243-263. Netto WJ, Planta DJU.
"Aggressive behaviour in dogs is an increasing problem in The Netherlands. In an attempt to find a solution to this problem the Dutch Ministry of Agriculture, Conservation and Fisheries has financially supported a study aimed at developing an aggression test for dogs. The primary goal is to use the test as an instrument for excluding very aggressive individuals of certain breeds from breeding."
