A new chapter begins for thousands of dogs born into abusive breeding in Cumberland, Virginia. As Reuters reports, the US Humane Society rescues about 4,000 beagles bred for animal testing, and many of the rescues have already found their forever homes.

The rescue process began after Envigo, a company that bred beagles and sold them to testing sites, closed after breaking animal welfare laws. Dogs that have spent their entire lives at the facility suffered from disease, malnutrition, overbreeding and crowded conditions.

Envigo closed its breeding business over the summer, which means the beagles born there now need stable, loving homes. The US Humane Society has begun placing dozens of dogs in shelters across the country, including the Animal Welfare League of Arlington in Virginia, Triangle Beagle Rescue in North Carolina and the Brandywine Valley SPCA in Pennsylvania.

All survivors need serious physical and emotional care. Along with receiving vaccinations and treatment for various medical issues, beagles will get their first taste of life as normal pets. Even mundane activities, such as sniffing grass or chewing on toys, will be new experiences for dogs that have been raised in cages, and they will need to be relaxed there.

The Humane Society has just begun its rescue efforts, and already many beagles have found permanent families. There is still a lot of work to do, however. The latest batch of animals to be rescued have lived the longest at the facility and will likely need the most rehabilitation. If you can’t help the rescued dogs by giving them a home, you can still support the cause by donating money or supplies to one of the shelters involved.
