Meet Rex - the shepherd mix that was once feral and killed cats. Last year, he was adopted by Ed Gernon from Whittier, CA. Then only a month after he was adopted, Rex spotted a nearly dying hummingbird with no feathers and covered in ants.
Ed Gernon nourished the hummingbird back the health - and the bird has not left their house since! They now call the bird Hummer.
Amazing how the rescued dog became the rescuer! Rex even shared his water bowl with Hummer.
