This is a list of links to some equine and companion animal charities and welfare associations on the internet. We encourage you always to support legitimate organizations and groups who selflessly work for the care of discarded and forgotten horses, cats and dogs. Please take the time to visit some of these sites, and contribute much needed funds, and possibly a new loving home for human society's "throwaways."

Although we've made an effort to include some of the many organizations that are effective and legitimate, we can't guarantee it; before donating, please assure yourself regarding the status of any organization to which you intend to contribute funds. Some sites offer secure on-line donation options; many offer phone numbers and addresses of animal rescue groups and shelters near you -- all you need to do is drop a check in the mail.
