Many animals need pet medication after being attacked by dangerous dogs, and the cost of putting these aggressive animals down amounts to around £70 million per year.
As such, the RSPCA is calling for the government to look into improving legislation surrounding the Dangerous Dogs Act to place responsibility on the owner rather than the breed.
Claire Robinson, government relations manager at the charity, said: "Our appeal for improved legislation is nothing new. The coalition government itself even stated after the general election that it would 'promote responsible pet ownership ... and will ensure that enforcement agencies target irresponsible owners of dangerous dogs'.
"The government pledged to do something about this - we need them to prove that statement was not a false promise."
The Dangerous Dogs Act was passed in 1991 in response to various incidents of serious injury or death following attacks by dogs.
Four breeds that were identified by the act were the Pit Bull Terrier, Japanese Tosa, Dogo Argentino and Fila Brasileiro.
