Aggression in 108 dog breeds and six crosses was ranked by 185 members of the Companion Animal Society of the New Zealand Veterinary Association. The Rottweiler and German Shepherd were categorised as extremely aggressive and the Akita, Basengi, Chihuahua (long-coated and short-coated), Chow Chow, Cocker Spaniel, Shar pei and Welsh Corgi (Cardigan and Pembroke) were classified as very aggressive. A chi-squared test of data from the twenty most popular breeds showed that significant differences were perceived between the breeds. Cocker Spaniels, Pembroke Welsh Corgis, German Shepherds and Rottweilers were more aggressive than Staffordshire Bull Terriers, Border Collies and Doberman Pinchers, which were more aggressive than Cavalier King Charles Spaniels, Bichon Frise, English Springer Spaniels, German Shorthaired Pointers, Weimaraners, Labrador Retrievers, Golden Retrievers, Newfoundlands, Dalmatians, Boxers, Bulldogs, Bull Mastiffs and Rough Collies.
