The inspection protocols of the Swedish police, based on the Act (2007:1150) on Supervision of Dogs and Cats, were used to examine the characteristics of 101 seized dogs, their owners, and the circumstances in which the attacks occurred. Most common reasons to seize a dog was that the dog owner was not following a previous order or ban, or that the dog had attacked and caused damage to humans or animals. The most common circumstances of the attacks involved dogs that escaped from gardens, unleashed dogs on walks and attacks by dogs on a leash. Bull breeds caused the highest number of injuries, the most serious injuries, and they were most often categorized as high risk, followed by Rottweilers and German Shepherds. Affenpinscher, Chihuahua, Cocker Spaniel, Japanese Spitz, Pug, Shih Tzu, Shetland Sheepdog and Golden Retriever were identified as victim breeds. The seized dogs had caused substantial harm to humans, animals, and their environment. The largest proportion of dogs returned to owners occurred in the Stockholm region.
