WEST OLIVE, Mich. (WZZM) - The Michigan Humane Society, based in Detroit, is now requiring appointments to surrender an animal.

While the policy is not going into effect everywhere, many shelters agree more needs to be done to help unwanted pets.

Whether theanimals arecute and friendly -- or come from a troubled home --Sue Ann Culp with the Harbor Humane Society says no appointments are needed.

"We'rean open access shelter," says Culp. "We accept anything."

The Michigan Humane Society, though,is now requiring prior calls before animals can be dropped off, which is meant to reduce the number of animals beingeuthanized.

"I think every shelter is concerned about how many animals are euthanized," says Culp.

Culp says the Harbor Humane Society has a 15-step process before an animal will be euthanized.

"Wehave a lot of animals that have been severely hurt or have been abused to the point they cannot be saved," says Culp.

Still, hundreds of animals are killed at the shelter every year.

A non-profit group called the Michigan Pet Fund Alliance is using the internet todemonstrate how different organizations compare, when it comes to the number of animals that are euthanized every year.

According to the Alliance, the Humane Society ofWest Michigan in Kent County had more than 1,400 animals euthanized in 2011, the Allegan County Animal Shelter had just over 1,000, and the Harbor Humane Society had about 1,300 animals euthanized.

"We are below the 50% mark and would like to get it even lower than that," says Culp.

Culp says with 400 on-call volunteers, the shelter will continue to take animals with no appointment.

The Humane Society of West Michigan also requires an appointment before animals can be dropped off. The Harbor Humane Society says it is working on public education so people will get their animals spayed and neutered, and treat them well.
