Since 18-year-old Elizabeth was paired with her dog Bella, she's had fewer emergencies and fewer hospital trips from her disability. "Bella holds Elizabeth's life in her service," said Pam Macdade, Elizabeth's mother.Elizabeth was born with cerebral palsy. She's nonverbal and bound to a wheelchair. "We have reached as far as we could go with medications and surgeries," Pam Macdade said. "We had to start thinking outside the box."This led them to Bella, a service dog. Elizabeth also suffers from a rare form of epilepsy called west syndrome."It's not anything we can pinpoint or predict," Pam Macdade said. "I needed Bella to be able to sense the seizure before it came on so I could give Elizabeth rescue meds."Watch the video above for the full story.

An 18-wheeler carrying sawdust overturned in Arkansas early Wednesday morning, downing a traffic light and hitting another vehicle before bursting into flames. The accident happened around 6 a.m. After the semi-truck overturned, the sawdust inside the trailer caught fire and caused an explosion, shown in a nearby surveillance video. It took crews hours to clean the sawdust from the roadway. Police said amazingly, only the truck driver－a 33-year old man－was transported to a medical center with minor injuries. The semi slid and struck a car waiting to turn at the intersection. The 59-year-old woman driving the car was uninjured. Watch the video above for the full story.
