But most hauntingly, she was barely recognizable.
"Her whole entire side of her face was missing," Frazier says. "Her skin tissue was hanging. Most of her ear was gone."

Abigail had only spent a day at the shelter before Frazier and her husband brought the dog to Pets First Wellness Center in Estero, Florida.
The shelter's staff had given Abigail as much care as they could muster with limited resources. But it wasn't enough.
"They do what they can," Frazier says. "But the pain meds and antibiotics she was on for the injuries that she had were going to do nothing for her."
"Maybe another day or two and she probably would have passed from being septic," she says. "because her injuries were at least a week or two old."
