Ten breeds of dogs, including Alsatians and Staffordshire Bull Terriers, are being banned from council estates in Dublin.
Council tenants will be banned from owning Rottweilers
The city council said the moved follows 10 reported attacks on people since the start of the year. Children were the victims of three attacks.
The ban will be implemented through tenancy agreements.
The council said it has "a duty of care to all its tenants to ensure that they live in a safe environment".
In the first six months of 2007, 73 banned dogs were handed over by their owners and another 169 were picked up as strays, according to the council.
The ban has been in effect since 1 July.
Staffordshire Bull Terriers are included in the ban
The dogs involved in the attacks were Bull Mastiff, Pit Bull Terriers, Japanese Akita, Rothweilers and German Shepherds.
"The ban on these breeds will be implemented through the Tenancy Agreement thereby including all existing tenants as well as all future tenants," the council said.
