Large dog rescue options in Florida?

I've heard of a rescue in Palm Beach County that helps seniors, and it might be located near Jupiter, possibly near the Big Dog Ranch. They usually have space for bigger dogs since most people want smaller ones. The allergic cats issue can be tough - my cat gets sneezes just from the neighbor's dog passing by my door. If you call them early in the morning before their feeding rounds, you might have a better chance of getting someone on the phone.
