I recently discovered this resource, the Face Foundation and have added it to my resource page, but wanted to share it here too.

Face Foundation:  Many sick and injured pets are abandoned or euthanized because their owners are unable to cover the cost of their emergency or critical care needs.

The FACE Foundation provides financial assistance to animal owners who are unable to cover the full cost of their pets’ critical or emergency veterinary care.

If Face Foundation is unable to help you they have also provided a download-able pdf of other financial resources.

Update:  And another financial resource someone shared with me after I posted about Face Foundation (love my community!!)  Fairy Dog Parents
