A local greyhound breeder is prepared to take council to court for declaring his dog dangerous after it attacked and killed a cat three months ago.

​But he believed his six-year-old greyhound was provoked.

Last week a dog escaped from its home and entered a Donges Road property and savagely killed four one-week-old lambs, to the devastation of the owner and their family.

Under the Dangerous Dog Act, a dog can be declared dangerous by an authorised council officer or a local court if it has, without provocation, attacked or killed a person or animal (not including vermin).

Once a dog is declared dangerous, owners must ensure their dog is microchipped and lifetime registered, desexed, is not left in the sole charge of a person under 18 years, contained in an enclosure that meets regulation requirements,  wears a prescribed collar at all times, wears a muzzle and is securely leashed at all times when outside the enclosure.

Owners must also display dangerous dog warning signs and notify council if they are entering/leaving an area.
