SPCA of Texas and ARK which is the rescue that I volunteer for.

Also if there's a special pet rescue that I see on the news that needs financial help, I always send them a check.

A while back there was a story about a woman who only took hard luck cases that needed surgeries, paid for them, and nursed the dogs back to health. She had several dogs waiting to have various ailments repaired, as well as several in various stages of healing. There was one that had had his front legs broken and they were never set. She was literally begging for money for him, before it was too late to do the surgery. My husband still doesn't know how much money I sent to her, and he never will.
