Part 5 Division 1 Section 33
33   Meaning of “dangerous”
(1)  For the purposes of this Act, a dog is dangerous if it—
(a)  has, without provocation, attacked or killed a person or animal (other than vermin), or
(b)  has, without provocation, repeatedly threatened to attack or repeatedly chased a person or animal (other than vermin), or
(c)    (Repealed)
(d)  is kept or used for the purposes of hunting.
(2)  A dog is not, for the purposes of subsection (1) (d), to be regarded as being kept or used for the purposes of hunting if it is used only to locate, flush, point or retrieve birds or vermin. Vermin for the purposes of this subsection includes small pest animals only (such as rodents).
Note.
 If a hunting dog is declared to be a dangerous dog, the declaration does not necessarily mean that the dog cannot be used for the purposes of lawful hunting—see section 51 (3).
