If you've received a Notice of Intention

Before a dog can be declared menacing or dangerous, the council must issue a Notice of Intention, as required by the Companion Animals Act 1998 (CAA) s 35(1).

The Notice must outline the compliance requirements that will apply if a declaration is made, and your right to object within 7 days (CAA s 35(2)).

Once you receive the Notice, immediate obligations commence, and the 7-day objection period begins.

It is important to:

  • Understand the obligations you must comply with immediately
  • Decide whether you wish to lodge an objection within 7 days
  • Seek appropriate advice promptly if you need support

If you do not respond within the objection period, the council may proceed to declare your dog without further input from you (CAA s 37(3)).
