DOGS NSW welcomed a new rule requiring dog owners to muzzle "menacing dogs" in public.
"It horrifies us that anyone should get hurt by any dog," Dogs NSW director Pauline Hartwell, of Castle Hill, said.
"I think with dogs that are found to be dangerous, I have no problems with them being muzzled," Mrs Hartwell said.
"Where I do have concerns is around breeds being picked [for muzzling] without research."
The rule is part of a package of measures announced by Local Government Minister Don Page and Minister for Primary Industries Katrina Hodgkinson to respond to concerns about dangerous and threatening dogs in NSW.
The government intends to introduce the legislation into the spring session of parliament, giving councils' community safety and compliance officers new powers to require owners to muzzle "menacing dogs" in public, have them on a leash, under the control of a person aged over 18, and ensure they're de-sexed.
"We don't want to see any more people attacked or injured by dogs in The Hills," mayor Michelle Byrne said in reference to an unleashed German shepherd that attacked a woman and her border collie at Castle Hill Showground on August 5.
