Hornsby Council voted to approve a tender with the Carlton pound at a meeting last week after Willoughby Council took up its services in July.

The home was preferred over NSW Animal Rescue and Kempsey Park Partnership, which do not provide pound services.

Both councils will use temporary holding facilities at veterinary surgeries or council depots in their areas before transferring animals to Carlton.

Animals without identification and dangerous or feral animals will be destroyed.

The pound now services 15 councils in Sydney.

Sydney City Council signed an agreement for pound services with Sutherland Shire Council's Taren Point animal shelter in July.

Sydney Dogs and Cats Home general manager Christine Baramilis said their services were also under consideration by Warringah and Kur-in-gai councils.

Ms Baramilis said that over the past year they had prepared for expansion, updating the computer system and employing a veterinarian.

The service's re-housing rate is about 90 percent for dogs and 65 percent for cats.

"We are vaccinating animals upon admission for disease prevention and we aim to re-home as many as we can,'' Ms Baramilis said.

The pound has increased animal viewing hours until 4pm, Monday to Friday, and 1pm on weekends.
