LOS ANGELES—Ten beagles have been released after years as laboratory experiments but their 1,500-mile van trip to freedom in Los Angeles was extended because Mother Nature had one last test.

Beagle Freedom Project President Shannon Keith says the driver ran into a near-blizzard. The driver slept in the van and used a lot of newspaper for the dogs, who have never been on leashes or out of cages.

They all arrived Wednesday.

During the worst, electrical wiring blown off a home got wrapped around the van's rooftop air-conditioner. The defroster and heater failed and the driver bought a handheld heater to defrost the windows.

The mature dogs will be placed in foster homes until they learn to live outside a cage, then put up for adoption.
