Rescue underway

A dog meat slaughterhouse in Indonesia has killed an estimated 50,000 dogs over the last 15 years. We have a rare opportunity to close it down. Donate today to support the rescue, medical care and rehabilitation of the surviving dogs. Give them the chance to heal and support our work to put an end to cruelty like this.
