BOSTON -- State officials inspected a pet adoption facility Friday, weeks after the facility was put under quarantine.

NewsCenter 5's Sean Kelly reported state inspectors came to the facility to look at documents and to see the changes that have been made since the last parvo virus outbreak in March after as many as 10 puppies adopted from the facility died.

Officials with the state's Bureau of Animal Health focused on the pet isolation of the facility in Milford. The bureau is trying to figure out where two puppies became infected with the virus. Both dogs were held in quarantine for 48 hours.

"They are basically trying to figure out where the problem is to see if there is any correlation between the source, the transport, which organization brought them in, as well as looking at anything that may have been done to ensure that they did not have parvo," Massachusetts Bureau of Animal Health spokesman Brad Mitchell said.

Dr. Rodney Poling owns the facility.

"We are asked to quarantine and care for these animals and deem them healthy. But we have no idea what the source, the potential exposure and the potential disease is until it strikes," he said.

Some of the dogs that died last month came from Poling's facility in Holliston. He said that the problem was fixed and there is no connection to the site this time.

"They were seven and a half miles away from the Holliston facility," he said.

Poling agreed to stop taking in out-of-state dogs at the Milford and the Holliston sites.

In the meantime, the adoption organization called Paw Safe -- the group that brought the dogs in from Kentucky -- has been told to stop bringing dogs into the state.

"We are going to put a hold on that until we know what is going on and have assurance that there is no disease coming in or out of there," Mitchell said.

Poling said that he severed ties with Paw Safe.
