SAN ANTONIO -

Some San Antonio animal advocates are complaining that the city’s use of an annex on Brooks City Base to house dogs is leading to the deaths of many animals.

The Animal Care Services facility is off Stealth Road deep in the heart of the base and its location is familiar to few people.

There are dozens of kennels here, but animal advocate Tracy Voss said ACS is not doing these dogs a favor.

"If you are an adoptable dog and you end up over there, your chances of getting adopted are not good," Voss said.

Voss is a rescuer and said the public is mostly unaware of the facility, there are not any signs on how to get to Brooks and that adoptable dogs are sometimes left off the city's website.

There is a Facebook page called Brooks Babies-ARF and an online petition asking Mayor Julian Castro for help.

The petition calls the site a secret location where hundreds of dogs die.

Eight thousand people have signed the online petition.

"I would love to see Brooks shut down one day," Voss said.

ACS Director Kathy Davis said some of the criticisms are founded.

"It is remote, it is not an ideal condition, an ideal place for us, but it does give us the ability to give our pets more time to get more pets adopted out," Davis said.

Davis said the city got Brooks for very little money and it has helped save lives.

"Last year our live release rate was 61%,” Davis said. “We're already at 77% and I'm really tickled to tell you that the first 13 days of January we're at 83% live release."

Davis said there is a good reason why there are no signs leading visitors to the ACS holding facility at Brooks.

She said the contract for the land specifically states it is not open to the general public.

ACS inherited the contract with the land and only volunteers, rescue groups and people trying to find lost pets are allowed there.

But a new $5 million ACS facility that will house adoptions and a spay/neuter clinic near the zoo will be completed in October so Brooks' days may be numbered, making everyone happy.

The city estimates the new facility could adopt out an extra 3,000 pets each year.
