How volunteers across the country are stepping in to help 4,000 beagles rescued from breeding facility

One by one, nervous beagles are carried out of a van and into the arms of volunteers at Homeward Trails in Fairfax Station, Virginia. All the volunteers want is to nurture them and let them be dogs. 

The dogs were previously owned by Envigo RMS, which bred beagles for medical research. The company also supplied mice, rats, and some other animals, as well as some related services, to researchers.  

But last month, the company was ordered by a federal judge to surrender all the facility's beagles after federal officials accused the company of a series of animal welfare violations. Now, they're in need of new homes.
