The Chihuahua ended up at Fuzz Ball Animal Rescue in Hermiston, Oregon, after getting hit by a car while in labor.
Xena also had to have an emergency C-section, because her baby was too large for a natural birth.
On Wednesday, the rescue shared the happy ending to this harrowing tale: the Chihuahua mom survived her operations and so did her healthy baby boy.
“It is so wonderful to see that both are doing amazing! This is one heck of a miracle.
This mama is a warrior and so is her baby,” the rescue posted on Facebook.
“To have survived being on the streets, run over, in labor with a puppy that was too big to come out and then a c-section and leg amputation while in shock!
They are little miracles!”
According to WSET, the duo was later given the heroic names Xena and Marvel.
