the original 5,223 dogs. However, the 1997 amendments expanded eligibility, effectively continuing the Index. As of 2015, there were 3,001 Pit bull terriers on the Index, 6 Dogo Argentinos, 0 Fila Brasilieros, and 3 Japanese Tosas. As of 2018, there were 3,514 Pit bull terriers, 3 Japanese Tosas, 13 Dogo Argentinos, and 0 Fila Brazilieros. Reception and responses The Royal Society for the Prevention of Cruelty to Animals and the British Veterinary Association are both against the breed-specific legislation provisions of the Act (Section 1), mainly on the basis that there is no scientific evidence that all individuals of a breed are dangerous. However, data from the Metropolitan Police shows that in incidents involving 'dangerously out of control dogs' banned breeds account for about 20% of offences. Defra says "a large number of serious cases from a very small population of dogs in circulation, and that is striking evidence that there is an issue with this particular type of dog", while a Member of Parliament said "Despite the fact that dogs on the exempt list must be muzzled in public, that breed still accounts for almost 20% of all reported attacks. We know also that pit bulls have been involved in seven of the 31 fatal attacks that have occurred since 2005. That is highly disproportionate for one type of dog that is banned, and it underlines the need to be cautious about change in this area." The act only covers dog attacks causing physical injury to a human, not physical injury or death to other animals, and does not cover mental injury to a human witnessing such an attack (PTSD, for example). Efforts have been made to get the law changed. In some cases, injuries to humans have been ignored or not taken seriously by authorities because they were caused during a dog-on-dog attack. A 2018 proposal by PETA to have the Staffordshire Bull Terrier and American Bulldog added to the list of banned dogs spawned a petition in support of the Staffordshires which garnered 160,000 signatures. The proposal was debated by Parliament and rejected. George Eustice declared, "The Government have no plans at all to add Staffordshire bull terriers, or any other type of dog, to the list of prohibited dogs." The act has been described as a piece of rushed legislation which was an overreaction to a transient public mood. The Act is sometimes cited as an
